Catalytic membrane reactor for in-situ water removal in the synthesis of valuable chemicals

A method for forming liquefied petroleum gas from carbon dioxide and hydrogen, the method comprising:

• introducing carbon dioxide and hydrogen into a multi-channel ceramic catalytic membrane reactor at liquefied petroleum gas synthesis conditions to form liquefied petroleum gas, the catalytic membrane reactor comprising a hollow fiber with an outer surface with a water permeable membrane coating, the catalytic membrane reactor further containing a bi-functional catalyst material including a methanol synthesis catalyst component to catalyze reaction of carbon dioxide and hydrogen to form methanol and water and a dehydration catalyst component to catalyze dehydration of methanol to form liquefied petroleum gas and water,
• wherein upon formation the water permeates through the water permeable membrane coating and exits the reactor.
