TECHNOLOGIES FOR OBTAINING CATALYSTS FOR GLYOXAL PRODUCTION VIA VAPOR-PHASE OXIDATION OF ETHYLENE GLYCOL

The Tomsk Regional Center for Collective Usage takes an active part in projects executed by Tomsk State University to develop catalysts for the most important industrial processes of deep oil refining and gas processing. Technology for obtaining glyoxal synthesis catalysts [1] is one of successful developments.

Due to high activity and unique properties, glyoxal has widespread application in manufacturing of brisant substances and propellants, drugs (imidazole, tinidazole, metronidazole, quinoxaline, piridazone, etc.), disinfectants and pesticides, solutions for soil fixing, hydrolic fracture, well repair, preparations for gas cleaning from sulfur-containing compounds, polymers, low-toxic carbamide resins, glues, films, rubber fillers, additives to plastics, resins, basis of multiple vanish compositions, structural concrete, solutions for high-quality leather tanning, moisture-resistant glues and plasters, electronic boards, etc. Partners to the project are “Industrial Company Novokhim” LLC, “Glyoxal-T” LLC. The developed catalyst exceeds all foreign analogues in activity and service life, its action is based on functioning of finely dispersed particles of silver and copper applied upon the oxide matrix. Thermal stability is the catalyst’s important peculiarity: it can be applied at temperatures up to 700оС without catalyst ageing.

Figure 1. Catalyst of ethylene glycol vapor-phase oxidation

Using this catalyst enabled to launch the first Russian glyoxal production in Tomsk, its production capacity making 1,000 tons per year. Besides research study and catalyst tests carried out within the framework of the project, the Tomsk Regional Center for Collective Usage developed and metrologically certified “Method for glyoxal mass fraction measuring in aqueous solution of glyoxal via the gas chromatography method” (STO TGU 060 – 2009, # 168 dated 16.04.2009, Certificate of Attestation MVI # 224.09.11.038/2009 dated 28.04.2009) and the standard specimen of composition “Glyoxal, 40-% solution”.

Pilot trials of catalysts for synthesis of valuable chemical semi-products: glyoxalic acid and pyruvaldehyde (Fig. 1) are currently accomplished on the equipment of the Center for Collective Usage.

TECHNOLOGY FOR OBTAINING SUBMICROCRYSTALLINE AND NANOSTRUCTURES IN LARGE-DIMENSION CAST BILLET OF CONSTRUCTION MATERIALS AND TITANIUM ALLOYS VIA SEVERE PLASTIC DEFORMATION METHODS

Severe plastic deformation technology [2] includes multiple uniaxial pressing within the selected temperature conditions and changing the axis of strain, and subsequent rolling. The technology allows to get a titanium bar VT1-0 in nanostructured or submicrocrystalline conditions while preserving sufficient plasticity with mechanical properties comparable to properties of medical-purpose titanium alloys (VT, VT16). In contrast to titanium alloys, the VT1-0 bar does not contain alloying elements (aluminium, vanadium, molybdenum), which are harmful to a living organism. This determines its advantages as a material for medical-purpose items. Research and development work in the scope of the project resulted in creation of titanium dental implants. Implant development was carried out purposefully, upon the initiative by Professor V.K. Polenichkin, head of subdepartment of maxillofacial surgery and general dentistry at the State Educational Institution for Continuing Vocational Education at Novokuznetsk State Medical Refresher Institute (GOU DPO NGIUV) of the Federal Agency for Healthcare and Social Development (Roszdrav) (Novokuznetsk).

The outcome of the above research was development of a set of dental implants made of titanium and instruments and accessories (TU 942422.001-10), required for surgical and orthopaedic procedures. The implant construction ensures sparing traumatizing of the patient’s jaw (bone tissue self-threading takes place while implantation operation is performed), initial stability in the course of introduction into bone tissue of the jaw, bone tissue tight contact with the implant surface, capillary blood filling of the structure elements, which enables to reduce the period for osteointegration and patient’s rehabilitation. Clinical trials have proved that the designed implants meet qualifying standards, possess good operational and functional properties, are recommended for dental practice in the Russian Federation and for registration in the Federal Supervisory Agency for Health Care and Social Development (Fig. 2). After the dental implant set registration at the Federal Supervisory Agency for Health Care and Social Development takes place, it is planned to organize implant production in Tomsk and to arrange refresher courses for dentists in Novokuznetsk under the auspices of the State Medical Refresher Institute.

The developed technology for getting volumetric nanostructured billets in the form of bars and plates with a high level of mechanical and physical and operational characteristics  can also be applied as a material for producing structure components for contemporary equipment (for example, waveguides for magnetostrictive ultrasonic transducers) and is efficient for solving applied problems of mechanical engineering and aerospace industry. Further development of this direction is also promising for medical-purpose items (including manufacturing of prosthetic cardiac valve components).

TECHNOLOGY FOR MAKING LAMINATED AND GRADIENT THERMALLY STABLE COATINGS VIA MAGNETRON-ION SYNTHESIS  METHODS WITHIN A SINGLE PROCESS CYCLE

Works in the area of material science is performed on equipment of the Tomsk Regional Center for Collective Usage. Magnetron reactive sputtering of metals and high energy ion beam bombardment enable to synthesize coatings with depth-changing structural phase and chemical compositions, the so called gradient coatings [3]. The bottom layer of such coatings should ensure good conjugation with the substrate and high bearing capacity, the upper one – required functional characteristics of coatings (hardness, wear resistance, heat-resistance, etc.), the middle layer – should serve as a transitional binding agent and possess high relaxation ability and sufficient strength and viscosity.

Figure 3. Plasma magnetron-arc complex «SPRUT (Octopus

Solving the problem required investigation of structural-phase states, determination of components’ concentration profiles and their distribution along the thickness of nano-composite coating, as well as their influence on tribotechnical and mechanical properties of coatings. On the other hand, nanocrystalline state of coatings is nonequilibrium, which may lead to changing properties as a result of elastic relaxation, grain growth, phase transformations. A unique complex “SPRUT” was designed to apply gradient nano-structural coatings, and integrated study of coatings were carried out on the Center equipment while fine-tuning operating conditions (Fig. 3).

In the framework of work implementation, experimental models were obtained and laboratory wear resistance tests were executed for carbide inserts of drills made of fast-cutting steel and straight turning tools with hard-alloy plates with applied laminated coatings. The operational life after applying these coatings increased by 3–5 times for carbide blades, by 3.5 times for various types of drills, by 2 times for straight-turning tools, i.e., the designed laminated coatings should be efficient as protective coatings for instrument purposes. Experimental models were also made for frames and noses with laminated nanocomposite coatings applied upon their working surfaces for work of combined valves of compressors for high-pressure polyethylene production. The performed operational tests have proved that operational life of the equipment using processed components increases by more than 2 times.

The following large-scale projects are also implemented with the help of equipment of the Center for Collective Usage:

  • Establishment of diversified production of porous nanostructural nonmetallic inorganic coatings (the project is implemented jointly with the State Corporation “Rosnanotech” and Close Joint-Stock Company “EleCi”, Close Joint-Stock Company “MANEL” was founded) [4];
  • Development of original technologies for semiconductor materials and nanoscale structures with pre-assigned functional properties and establishment, industrial engineering and market launch of quantum-sensitive sensors, converters, components, devices and systems versatile functional nanoscale electronics (the project is implemented with participation of a number of industrial enterprises, including Open Joint-Stock Company “Research Institute of Semiconductor Devices”);
  • Development and implementation of series production of inorganic and organic nanoscale- and submicronic powders and materials based on them via pneumocirculating methods using self-propagating high-temperature synthesis (the project is implemented jointly with Limited Liability Company “Scientific Production Association “MIPOR”) [5];
  • Development of methodology for studying nanoscale materials biosafety.

Educational activity at the Tomsk Regional Center for Collective Usage is arranged with utilization of contemporary research complexes (analytical and manufacturing equipment), which meet the world standards in technical and operational characteristics of instrumentation pool, and make part of integral multilevel educational system for a new generation staff training and retraining for nanoscale industry [6].

Upon the order of the State Corporation “Rosnanotech”, the job retraining program entitled “Methods and technologies for forming interphase boundaries and nanostructural nonmetallic polyfunctional coatings” (520 hours) was developed and implemented using the Tomsk Regional Center for Collective Usage equipment. The program was executed in the framework of the project “Development and approbation of the program for advanced job retraining and learning complex, dedicated to investment projects of the State Corporation “Rosnanotech” in the field of diversified production of porous nanostructural nonmetallic inorganic coatings”.

Based on the Tomsk Regional Center for Collective Usage, the annual Workshop school “Research and metrology of nanoscale materials” takes place for a chain of centers for collective usage of scientific equipment.
