METHOD FOR PRODUCING LIQUEFIED PETROLEUM GAS

摘要

A liquefied petroleum gas mainly containing propane or butane is produced by passing a material gas containing at least one of methanol and dimethyl ether and hydrogen through a catalyst layer. The catalyst layer comprises, in an earlier location of the material gas flow, a catalyst sublayer which contains a catalyst for olefin-containing gas synthesis that is used when an olefin-containing gas is produced from at least one of methanol and dimethyl ether. The catalyst layer further comprises, in a latter location of the material gas flow, another catalyst sublayer which contains a catalyst for olefin-containing gas hydrogenation that is used when paraffin is produced through hydrogenation of olefin.
