摘要： In a coal gasification operation or similar conversion process carried out in the presence of an alkali metal-containing catalyst wherein solid particles containing alkali metal residues are produced, alkali metal constituents are recovered for the particles by contacting or washing them with an aqueous solution containing calcium or magnesium ions in an alkali metal recovery zone at a low temperature, preferably below about 249.degree. F. During the washing or leaching process, the calcium or magnesium ions displace alkali metal ions held by ion exchange sites in the particles thereby liberating the ions and producing an aqueous effluent containing alkali metal constituents. The aqueous effluent from the alkali metal recovery zone is then recycled to the conversion process where the alkali metal constituents serve as at least a portion of the alkali metal constituents which comprise the alkali metal-containing catalyst.

摘要： Carbonaceous solids such as coal and oil shale are fed to a high temperature processing vessel without bridging and plugging problems interrupting the flow of the solids into the processing vessel by passing the solids at a controlled rate from a feed vessel into a first conduit communicating with the feed vessel. The solids are then passed through the first conduit into a second conduit which communicates with the first conduit and the processing vessel, and which contains a scraper for scraping the inside walls of the conduit. The pressure in the feed vessel is maintained at a level higher than that in the processing vessel by passing a sufficient amount of a gas into the feed vessel such that the solids are passed through the second conduit into the processing vessel in dense phase pneumatic flow as the scraper scrapes the inside walls of the second conduit thereby preventing any bridging or plugging from occurring. Normally, the scraper will consist of a wire helix which is rotated inside the second conduit.

摘要： In a coal gasification operation or similar conversion process carried out in the presence of an alkali metal-containing catalyst wherein solid particles containing alkali metal residues are produced in the gasifier or similar reaction zone, alkali metal constitutents are recovered from the particles by withdrawing and passing the particles from the reaction zone to an alkali metal recovery zone in the substantial absence of molecular oxygen and treating the particles in the recovery zone with water or an aqueous solution in the substantial absence of molecular oxygen. The solution formed by treating the particles in the recovery zone will contain water-soluble alkali metal constituents and is recycled to the conversion process where the alkali metal constituents serve as at least a portion of the alkali metal constituents which comprise the alkali metal-containing catalyst. Preventing contact of the particles with oxygen as they are withdrawn from the reaction zone and during treatment in the recovery zone avoids the formation of undesirable alkali metal constituents in the aqueous solution produced in the recovery zone and insures maximum recovery of water-soluble alkali metal constituents from the alkali metal residues.
