A process for gasification of a carbonaceous material for example wherein said carbonaceous material is selected from the group consisting of carbonaceous material, carbonaceous liquid product, carbonaceous industrial liquid recycle, carbonaceous municipal solid waste (MSW or msw), carbonaceous urban waste, carbonaceous agricultural material, carbonaceous forestry material, carbonaceous wood waste, carbonaceous construction material, carbonaceous vegetative material, carbonaceous industrial waste, carbonaceous fermentation waste, carbonaceous petrochemical co-products, carbonaceous alcohol production co-products, carbonaceous coal, tires, plastics, waste plastic, coke oven tar, fibersoft, lignin, black liquor, polymers, waste polymers, polyethylene terephthalate (PETA), polystyrene, sewage sludge, animal waste, crop residues, energy crops, forest processing residues, wood processing residues, livestock wastes, poultry wastes, food processing residues, fermentative process wastes, ethanol co-products, spent grain, spent microorganisms, and mixtures thereof, to produce a hot syngas, said process comprising: (a) contacting said carbonaceous material with a first molecular oxygen-containing gas and optionally with one or more of steam and CO 2 in a moving bed gasification zone to gasify a portion of said carbonaceous material and to produce a first gaseous product; (b) contacting a remaining portion of said carbonaceous material with a second molecular oxygen-containing gas and optionally with one or more of steam and CO 2 in a burn-up zone to gasify additional portion of said carbonaceous material and to produce a second gaseous product and a solid ash comprising carbon; (c) combining said first gaseous product and said second gaseous product to produce a raw syngas comprising carbon monoxide, carbon dioxide (CO 2) and tar; and (d) contacting said raw syngas with a third molecular oxygen containing gas in a tar destruction zone to produce said hot syngas, said tar reduction zone being connected to the gasification zone and/or burn-up zone through one or more connecting zones or throats, and said third molecular oxygen containing gas being introduced into the tar reduction zone through one or more gas inlets attached to said one or more connecting zones, wherein a CO/CO 2 molar ratio in said hot syngas is greater than about 0.75 and the ratio of carbon content of solid ash to carbon content of carbonaceous material feed is less than about 0.1, such as less than 0.05, for example less than 0.01, said carbon content being measured according to ASTM D6316. (a) contacting said carbonaceous material with a first molecular oxygen-containing gas and optionally with one or more of steam and CO 2 in a moving bed gasification zone to gasify a portion of said carbonaceous material and to produce a first gaseous product; (b) contacting a remaining portion of said carbonaceous material with a second molecular oxygen-containing gas and optionally with one or more of steam and CO 2 in a burn-up zone to gasify additional portion of said carbonaceous material and to produce a second gaseous product and a solid ash comprising carbon; (c) combining said first gaseous product and said second gaseous product to produce a raw syngas comprising carbon monoxide, carbon dioxide (CO 2) and tar; and (d) contacting said raw syngas with a third molecular oxygen containing gas in a tar destruction zone to produce said hot syngas, said tar reduction zone being connected to the gasification zone and/or burn-up zone through one or more connecting zones or throats, and said third molecular oxygen containing gas being introduced into the tar reduction zone through one or more gas inlets attached to said one or more connecting zones,
