Production of hydrocarbon synthesis gas

We've lately been reporting on the use of "Oxygen donor" substances, the oxide compounds of specific metals, in Coal gasification processes, as, for one especially intriguing example, in our report of:

Oklahoma Oxygen Donor Coal Gasification | Research & Development; concerning: "United States Patent 4,496,370 - Zinc Oxide-Char Gasification Process; 1985; Phillips Petroleum Company; Abstract: In the gasification of char with zinc oxide, the improvement which comprises reacting the off-gas stream of gaseous zinc and carbon monoxide with steam at elevated temperatures in a second reactor means thereby oxidizing the zinc to zinc oxide and yielding a second gaseous stream containing carbon monoxide and hydrogen';

United States Patent: 4450066

As seen in one of our earlier reports, as accessible via:

USDOE Hires Exxon to Improve Low-Rank Coal Liquefaction | Research & Development; concerning: "United States Patent 4,304,655 - Liquefaction Process; 1981; Assignee: Exxon Research and Engineering Company; Abstract: Scale formation during the liquefaction of lower ranking coals and similar carbonaceous materials is significantly reduced and/or prevented by pretreatment with a combination of pretreating agents comprising SO2 and an oxidizing agent.Government Interests: The Government of the United States of America has rights in this invention pursuant to Contract No. EF-77-A-01-2893 awarded by the U.S. Department of Energy; This invention relates to an improved process for ... liquefying coal and similar carbonaceous materials";

Gasification of carbonaceous solid fuels

 

We've lately been documenting the fact that Coal can be gasified, i.e., converted into a synthesis gas mixture of Hydrogen and Carbon Monoxide well-suited for catalytic chemical condensation into liquid hydrocarbons, with very little co-production of Carbon Dioxide, by supporting the necessary partial oxidation reactions with an Oxygen donor substance, rather than with Air or purified Oxygen.

Production of industrial gas mixture of hydrogen and carbon monoxide

We've lately been documenting the use of "Oxygen donors" in various Carbon conversion processes; such Oxygen donors being, typically, oxide compounds of various specific metals that are able to supply Oxygen, in a controlled and restricted way, to effect the partial oxidation of Coal, and other Carbon-containing substances.

The purpose of their use, again, is to restrict the supply of Oxygen so that, even though the oxidation reaction is able to proceed, it is incomplete and results in the production of relatively more of the desired Carbon Monoxide, as opposed to the less-desired Carbon Dioxide.

PROCESS FOR THE PRODUCTION OF A CARBON MONOXIDE CONTAINING GAS

As we again recently documented, in our report of:

Bayer Improves Coal + CO2 = Carbon Monoxide | Research & Development; concerning, primarily: "United States Patent 7,473,286 - Carbon Monoxide Generator; 2009; Bayer Material Science, AG, Germany; Abstract and Claims: A generator (which produces Carbon Monoxide) having a purity of greater than 96%, preferably from 97 to 98% (via a) continuous process in which carbon-containing raw materials are reacted with oxygen and carbon dioxide";

it is perfectly practical and feasible to recycle Carbon Dioxide, reclaimed from whatever source, by reacting it in a controlled fashion with "carbon-containing raw materials" such as Coal.
