▎ 摘　　要

NOVELTY - Preparation of functionalized graphene oxide composite film for separation of olefins and alkanes, involves carrying out cleaning and surface treatment of porous ceramic carrier, dispersing graphene oxide in water to obtain graphene oxide dispersion, reacting porphyrin with silver salt in water to coordinate silver with porphyrin obtaining silver porphyrin solution, adding graphene oxide dispersion and porphyrin silver solution to water, diluting and mixing uniformly to obtain mixture (A), subjecting mixture (A) to pressure filtration deposition method on porous ceramic support to prepare functionalized graphene oxide composite film. USE - Preparation of functionalized graphene oxide composite film for separation of olefins and alkanes (all claimed). ADVANTAGE - The preparation functionalized graphene oxide composite film is simple, economical, has low energy consumption, easy to operate, simple process, and has high efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of functionalized graphene oxide composite film for separation of olefins and alkanes.
