FRACKING WITH C02 FOR SHALE GAS REFORMING TO METHANOL

摘要

A method of producing methanol from shale gas and CO₂ by the exclusive dry CO₂ fracking of shale rock by injection of gaseous CO₂ at a pressure between 10 and 100 atm to extract shale gas and recover it together with used CO₂; combining and admixing produced shale gas containing CO₂ and steam to produce a mixture of methane : carbon dioxide : water having a molar ratio of 3:1:2 for conducting the bi-reforming reaction to form a mixture of hydrogen and carbon monoxide having a molar ratio of 2:1 to 2.1:1; and converting the hydrogen and carbon monoxide under conditions sufficient to exclusively form methanol.
