Abstract
A method of separating acetylene from a gas mixture comprising acetylene is provided. The method involves the use of a hybrid porous material with an affinity for acetylene adsorption. The hybrid porous material comprises a three-dimensional structure of metal species (M) and first and second linker groups (L1 and L2), wherein the metal species (M) are linked together in a first and second direction by first linker groups (L1) and are linked together in a third direction by second linker groups (L2) to form the three-dimensional structure. The hybrid porous materials may have a high selectivity for acetylene and/or a high capacity for acetylene adsorption. The method may be particularly useful for the purification of ethylene gas contaminated with acetylene during an ethylene production/purification process. The method may be particularly useful for the large scale separation of acetylene from other gases such as ethylene and carbon dioxide, during an acetylene production/purification process.
