Abstract
This invention relates to a process for synthesizing hydrocarbons; more particularly, the invention relates to a process for synthesizing long-chain hydrocarbons known as polymethylene from carbon monoxide and hydrogen or from carbon monoxide and water or mixtures thereof in the presence of a catalyst comprising iron and platinum or palladium or mixtures thereof which may be supported on a solid material, preferably an inorganic refractory oxide. This process may be used to convert a cabon monoxide containing gas to a product which could substitute for high density polyethylene.
Claims6
A method for synthesizing polymethylene comprising contacting a mixture of hydrogen and carbon monoxide or water and carbon monoxide or mixtures thereof in a solvent with a slurry of a catalyst composed of palladium or platinum or mixtures thereof supported on a solid phase with iron deposited thereon wherein iron comprises at least 40 weight percent and platinum or palladium or mixtures thereof comprise at least 1 weight percent based on the total catalyst weight, under conditions sufficient to convert the gaseous mixture to polymethylene.
