Abstract
A process for treating gas streams containing hydrogen and hydrocarbons. The process includes a membrane conditioning step to remove C.sub.5 -C.sub.8 hydrocarbons, followed by a selective adsorption or membrane separation step to separate hydrogen from methane. The membrane conditioning step uses a membrane selective for C.sub.5 -C.sub.8 hydrocarbons over hydrogen.
