Practice of Preparation of a Cobalt Catalyst for Hydrocarbon Synthesis from CO and H2

Abstract

The experience of the industrial technology of a cobalt catalyst supported on granulated silica is generalized. The catalyst is intended for selective synthesis of C5+ hydrocarbons, including high-molecular C35+ HC, from CO and H2. The technology is implemented by CJSC Samara Catalyst Plant. The process parameters were adapted for the available facilities during preparation of a pilot catalyst batch. Optimal technological conditions of the support pretreatment (vacuuming to prevent granule cleavage), impregnation (80 °C for 0,5 h) and the catalyst thermal treatment (programmed mode with the maximal temperature of 400 °C for 9 h in total) were determined. Physicochemical and catalytic properties of the prepared pilot batch (1 m3) meet the required specifications.
