Patent Abstracts

Method of converting low molecular weight hydrocarbon gases into hydrocarbons of higher molecular weight, which comprises mixing the hydrocarbon gases with CO₂, recycled gas from the synthesis gas, and steam in such proportions as to provide an atomic proportion of H, C, and O of about 4 : 1 : 1, contacting the mixture with a reforming catalyst at a sufficiently high temperature and for a sufficient time to convert the mixture chiefly into H₂ and CO whereby a make gas is produced having a H₂ : CO ratio of about 2 : 1, suspending a synthesis catalyst in the make gas, maintaining the temperature of the catalyst suspension at a level in the approximate range 225º-425º F. and substantially constant and uniform by directly admixing relatively cool materials with the mixture in a synthesis zone, continuing the contact of make gas with suspended catalyst in the synthesis zone for a period of time sufficient to effect synthesis, then separating suspended catalyst from the gases and reaction products, separating unreacted gases and low molecular weight hydrocarbon gases from high-molecular-weight reaction products, and recycling the unreacted gases and low-molecular-weight hydrocarbon gases to the mixing step.
