Effect of the Composition of Synthesis Gas on a Combined Process of the Synthesis and Hydrofining of Hydrocarbons from CO and H2
The results of studying the effect of the composition of synthesis gas (CO + H 2 ) on the combined process of hydrocarbon synthesis and hydrofining on the Co-SiO 2 /ZSM-5/Al 2 O 3 composite catalyst at a pressure of 2.0 MPa and a temperature of 240°C are presented. The raw material was concentrated...
