Process for gasification of coal and organic solid wastes

A process for coal and organic solid waste gasification comprising the steps of:

• converting water in an aqueous feed stock to steam;
• gasifying coal and organic solid waste feedstocks in the presence of said steam using a granular fluidized clay to produce a gaseous product composed primarily of carbon monoxide and hydrogen;
• removing hydrogen chloride from said gaseous product by injecting barium carbonate to react with hydrogen chloride to form barium chloride, and removing said barium chloride;
• removing hydrogen sulfide from said gaseous product by contacting said gaseous product with lime to react with hydrogen sulfide to from calcium sulfide, and removing said calcium sulfide for external oxidation to calcium sulfate and recovering said calcium sulfate;
• thereafter removing residual micronic particulates and vaporized metallic chlorides from said gaseous product using high temperature precipitating agents to finally clean the product gases consisting essentially of carbon monoxide and hydrogen;
• regenerating barium carbonate by reacting said recovered barium chloride with a water solution of sodium carbonate to from barium carbonate and sodium chloride;
• circulating carbon containing granular fluidized clay, used to gasify the coal and organic solid waste feedstocks in the presence of steam, to an air burner to burn said carbon to yield a producer gas containing carbon monoxide and carbon dioxide, and returning the decarbonized granular fluidized clay to gasify additional coal and organic solid waste feedstocks in the presence of steam;
• and
• reducing a metal oxide with said carbon monoxide in said producer gas to produce a reduced metal, and reoxidizing said reduced metal to metal oxide with steam to generate hydrogen gas.
