United States Patent: 3972958
Yesterday, we submitted a representative sample of seven Coal-to-Liquid conversion technologies invented, developed and patented by the old Mobil Oil Corporation, now a component of ExxonMobil.
We do understand that those US Patents' titles, and some of those patents' abstracts and descriptions, don't, in all cases, specify Coal or Coal Conversion, even though that is, we assure you, what those detailed, well-developed hydrocarbon processing technologies are all about.
Lest anyone doubt that, we submit herein, for now, just one other US Patent issued to Mobil Oil Corporation.
It's intent and purpose should be perfectly clear from our excerpts of:
"United States Patent 3,972,958 - Conversion of Coal to High-Octane Gasoline
August 3, 1976
Inventor: William Garwood, et. al.; Assignee: Mobil Oil Corporation
Abstract: An integrated process for converting coal to high octane gasoline by gasifying the coal in such manner as to form a gas comprising carbon oxides, hydrogen and methane; contacting this gas in one or a series of steps with one or a series of catalysts, respectively comprising a special high silica to alumina ratio zeolite; converting the carbon oxides and hydrogen by such contact to a product comprising water, high octane aromatic gasoline and light hydrocarbon gases; alkylating the C3 and C4 olefins with the isobutane in the light gases to produce alkylate gasoline; admixing the aromatic and alkylate gasoline; and subjecting the C2 portion of the product to steam reforming whereby additional synthesis gas to be admixed with the gas produced by coal gasification is formed."
