Title:
METHOD FOR PRODUCING LIQUEFIED PETROLEUM GAS
Document Type and Number:
WIPO Patent Application WO/2006/016583
Kind Code:
A1
Abstract:
A synthesis gas is produced from a raw material gas containing a carbon-containing raw material such as natural gas and a carbon dioxide-containing gas which is separated from a reaction product gas obtained by dimethyl ether synthesis reaction and recycled. A reaction product gas containing dimethyl ether and carbon dioxide is produced from the thus-obtained synthesis gas, and a dimethyl ether-containing gas is obtained by separating a carbon dioxide-containing gas from this reaction product gas. A liquefied petroleum gas is then produced from the thus-obtained dimethyl ether-containing gas and hydrogen.
