Name of the project: Alkylation of isobutene by light olefins based on solid catalysts using reaction-rectification technologies

Strategy for Scientific and Technological Development Priority Level: б


Goals and objectives

Research directions: Catalytic processes for oil refinery

Project objective: Alkylation of isobutene by light olefins based on solid catalysts


The practical value of the study

  • We have described theoretical basics of processes that are crucial for synthesis of active and selective alkylation catalysts. We have found connection between modification stages, structural strength and acid-base qualities of produced catalysts.
  • Our researchers have found that an important role in moulding of catalysts is played by zeta potential of particles. It determines extent of their electrostatic interaction. We have determined impact of time and conditions of the reaction stage on change of texture qualities, residual concentration of Bronsted and Lewis acid sites and number of compounds adsorbed on the surface of deactivated catalysts.
  • A methodology for creating two types of efficient alkylation catalysts: synthetically modified Y zeolite based on combination of methods of decationation,   dealumination and ion exchange, and a massive catalyst based on zirconium hydroxide sulfate and pseudoboehmite.
  • A new reaction-rectification alkylation process that uses special side-mounted reaction sections where nickel-containing zeolite catalyst is distributed across segments. The reaction sections ensure efficient procedure of regeneration by hydrogen, removal of evaporating reagents, alkylate recirculation, distributed supply of olefin raw materials and recirculating isobutene.
  • We have conducted experimental probation of modern reaction-rectification alkylation process with side-mounted reaction sections using prototype test rig. We have obtained data for scaling and designing a modern industrial alkylation device.
  • A complex for researching catalysts that includes methods of nitrogen optometry., infrared spectroscopy of adsorbed pyridine, X-ray fluorescence element analysis, derivatographic analysis, ultraviolet spectroscopy, temperature-programmed reduction, oxidation and desorption of probe molecules, X-ray phase analysis, granulometric analysis by laser diffraction and chromatography–mass spectrometry.

Implemented results of research:

  • We have developed an energy efficient technology to produce alkyl petroleum by using modern reaction and mass exchange processes.
  • The Laboratory has obtained 5 patents for inventions and 2 for useful models: «A method of synthesis of a catalyst and a catalyst for alkylation of isobutan by isobutene», «A device for alkylation of isobutan by olefins based on a solid catalyst», «A method for synthesizing a spherical catalyst and a catalyst for alkylation of isobutan by isobutene», «A catalyst for oxidation condensation of methane and a method of its synthesis», «A device for isomerisation of light petroleum fractions», «A method to synthesize a catalyst for alkylation of paraffin by olefins».
  • Technological regulation and a road map for the technological process of preparing the НY-AS-ZS-500 catalyst. An experimental lot of the catalyst have been produced.
  • 9 completed contracts and signed partnership agreements to support development of new catalytic materials and technologies with leading engineering companies of Saint Petersburg in oil and gas refinery.
