Synthesis of high molecular weight hydrocarbons from CO and H2 on a cobalt catalyst
Abstract
A synthesis of hydrocarbons from CO and H2 was carried out over a cobalt catalyst. The selectivity and productivity of the reaction were studied in dependence on temperature, pressure, space velocity, and composition of the synthesis gas. It was found that a temperature increase of 17 °C at volumetric feed rates of 60 h–1 and 100 h–1 reduces the process selectivity toward macromolecular hydrocarbons C35+ by 24 % and 69 %, respectively. The change of pressure from 0,1 to 2,0 MPa increases the selectivity, whereas a change in the gas space velocity from 60 to 300 h–1 leads to its decrease. It was shown that the production of high molecular weight hydrocarbons C35+ (ceresin) requires the use of concentrated mixtures of synthesis gas. The actual composition of resulting hydrocarbons differs from the Anderson – Schulz – Flory (ASF) distribution, which indicates that the theoretical simulation of actual distribution should use more complex dependencies. The results of this applied research are intended to design a pilot plant for production of ceresin 100.
