Abstract:

The whole process flow industrial sidestream experiment is conducted for the natural gas synthesized with coke oven gas. The scale of experiment is 150m3/h of coke oven gas. The experiment of methanation unit lasts for 1 000h. The experiment result shows that M-849 catalyst has good methanation activity and selectivity and possesses good stability after many times start and stop and good performance of short term over temperature. The operation of the process with two-stage thermal insulation methanation of steam spatchcocking and no reacting gas circulating is smooth and simple. The composition of gas at the outlet meets the requirement of design indexes.
