NOVELTY - A slurry of solid effluent obtained directly from gasification process in water is fed to vibrating screen device (30) to produce solid product (P1) and water slurry of solid product (P2). The slurry of product of (P2) is fed to separation device (50) to produce water slurry streams (S1,S2). The stream (S2) is fed to a gasification zone (20). The carbonaceous fuel is partially oxidized in zone (20) at elevated temperature and pressure operated in slagging mode to produce gaseous product stream comprising carbon monoxide and solid slag effluent comprising ash and unconverted carbon.    USE - For recovery of carbon value from solid effluent obtained from gasification process for production of carbon monoxide and hydrogen.    ADVANTAGE - The carbon values contained in the solid slag effluent are recovered and recycled to the gasification reactor. The efficiency of gasification process is increased and consumption of feed stock is reduced. Use of expensive solid handling equipment such as front end loaders or slag drag conveyers, is eliminated without causing operation swings that are detrimental to production of syngas (feedstock for producing useful organic compounds).    DETAILED DESCRIPTION - A slurry of solid effluent obtained directly from gasification process in water is fed to a vibrating screen device designed and operated to produce solid product (P1) having average particle size of greater than 850 microns and water slurry of solid product (P2) having average particle size of less than 850 microns. The water slurry of product of (P2) is fed to a separation device to produce water slurry stream (S1) of solids comprising particles having average particle size of less than 150 microns and water slurry stream (S2) of solids comprising particles having average particle size of 150-850 microns. The stream (S2) is fed to a gasification zone (20). The carbonaceous fuel is partially oxidized in the zone (20) at elevated temperature and pressure operated in slagging mode, to produce gaseous product stream comprising carbon monoxide and solid slag effluent comprising ash and unconverted carbon.
