▎ 摘　　要

NOVELTY - A domestic oil gas and part of volatile organic gas purifying method involves introducing oil gas and specific volatile organic gas into the reactor by gas influx devices. The gas is purified by fully contacting with the graphene sponge cylinder, recycled the graphene sponge tube by cleaning the inner wall of the graphene sponge tube and applied electric heating, where the graphene sponge cylinder in the reactor is a cylinder made of graphene foam and/or a graphene sponge loaded with an efficient catalyst and an industrial wool felt. USE - Method for purifying domestic oil gas and part of volatile organic gas. ADVANTAGE - The method enables purifying the domestic oil gas and part of volatile organic gas with high absorption efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an oil-gas separating device.
