Process for the production of unsaturated hydro-carbons

摘要

In a process for the production of unsaturated hydrocarbons comprising catalytic conversion of a feed gas comprising carbon oxides and hydrogen, the improvement which comprises carrying out said conversion at a temperature of 250 DEG to 350 DEG C. and under a pressure of 10 to 30 bars, said catalyst comprising at least one difficultly reducible oxide of the transition metals of Groups V and/or VII of the Periodic Table combined with at least one metal of Group 8 of the Periodic Table.
