A spherically granular, amorphous, mesoporous catalyst was obtained by supporting V2O5 on synthesized by direct sol-gel method of ZrO2-SiO2 hydrogel and was identified by SEM, XRD and N2 adsorption / desorption. It is shown that its hydrothermal and alcohol treatment increases the specific surface, volume and width of pores and leads to an increase in the yield of propylene in the reaction of propane dehydrogenation and decreases the temperature of reaching its high values.

The article deals with the problems of ethylene and propylene production in the world. The optimal parameters of the pyrolysis process are described. The alternative types of raw materials are analyzed. Hydrocracking vacuum gasoil, straight-run gasoil vacuum obtained from the West-Ukrainian oil, as well as dewaxing filtrate are proposed as raw materials.  Наведено дані щодо виробництва етилену і пропілену у світі. Описано оптимальні параметри проведення процесу піролізу.
