Abstract:

PURPOSE: To obtain C₅₊ hydrocarbons with high selectivity while enhancing a CO conversion ratio and reducing the formation of CH₄ by bringing H₂ containing no light hydrocarbon and CO into contact with each ether in the presence of added water at high temp. in a fixed bed using a catalyst composed of Co and reduced in the net consumption of water.

CONSTITUTION: H₂ containing no light hydrocarbon and CO are brought into contact with a catalyst composed of Co in the presence of added water at 180-240°C under 5-30 atmospheric pressure to obtain C₅₊ hydrocarbons. The addition of water is performed by adding water to supply matter to introduce the same into a reaction zone or by directly adding water to the reaction zone and the addition amt. thereof is set to 1-70 vol.% (pref., 5-30 vol.%) with respect to the total amt. of H₂O, CO and H₂. Both of CO converting activity and a C₅₊ hydrocarbons selectivity are increased by adding water to the reaction zone and, at the same time, the formation of methane can be reduced.
