PREPARATION OF LIQUID HYDROCARBON FROM SYNTHESIS GAS

摘要

PURPOSE:To obtain a liquid hydrocarbon, especially gasoline fraction, in high yield from a synthesis gas under mild conditions, by using a novel catalyst consisting of a catalytic component capable of converting a synthesis into a noncycl ic hydrocarbon and a specific crystalline silicate component. CONSTITUTION:A synthesis gas is reacted using a catalyst consisting of (A) a catalytic component (e.g., Co-based catalyst such as Co-ThO2-MgO-diatomaceous earth, etc.) capable of converting a synthesis gas into a noncyclic hydrocarbon and/or an oxygen-containing noncyclic hydrocarbon and (B) a crystalline silicate component containing (i) Si and/or Ge, (ii) H, an alkali metal and/or alkaline earth metal, (iii) Al and/or Ga and (iv) a metal (with the proviso that Al, Ga, Si, Ge, are omitted) (e.g., B, etc.) belonging to III A, IV A, V A, III B, IV B, V B, VI B, and VIII groups of periodic table. The reaction is preferably carried out at 250-450 deg.C at 10-150kg/cm<2> at a gas space velocity of 1,000-10,000hr<-1>.
