Experience in introducing a cobalt catalyst technology for the synthesis of hydrocarbons from CO and H2

Resumo

The experience in introducing the technology of for the production of a silica-supported cobalt catalyst under industrial conditions is summarized. The catalyst is designed for the selective synthesis of С₅₊ hydrocarbons from СО and Н₂, including macromolecular hydrocarbons С₃₅₊. The technology has been implemented at ZAO Samara Catalyst Factory. Parameters of the technological process are adjusted to allow for the features of existing equipment in preparing an experimental industrial lot of catalysts. The optimum technological mode of support preparation (evacuation to avoid granule cracking), its impregnation (at 80°С over 30 min), and the thermal treatment of the catalyst (in programmed mode at a maximum temperature of 400°С over a total of 9 h) are determined. The catalysts of an experimental industrial lot of 1 m³ conform to the new technical conditions in their physicochemical and catalytic properties.
