NOVELTY - The process comprises introducing a solid carbonaceous feedstock and a gas stream into a chamber and then mixing to produce a warm solid-gas mixture comprising a dry solid carbonaceous feedstock, where: the gas stream comprises syngas produced by a gasification reactor (10) comprising a reactor upper section (40) and a reactor lower section (30); and the warm solid-gas mixture is maintained at a temperature of 500-800 degrees F that minimizes the formation of tar when inside the chamber, and separating the warm solid-gas mixture in a separating device (50).    USE - The process is useful for converting a feedstock such as carbonaceous materials into desirable gaseous products such as synthesis gas that is useful for generating electricity and for producing chemicals such as hydrogen, methanol, ammonia, synthetic natural gas or synthetic transportation oil, where feedstock includes coal, petroleum coke and petroleum residue and the carbonaceous materials include lignite, bituminous coal, sub-bituminous coal and carbonaceous solids derived from oil shale, tar sands, pitch, biomass, concentrated sewer sludge, bits of garbage and/or rubber.    ADVANTAGE - The process ensures conversion of the feedstock into the desirable gaseous products with high energy efficiency and less feedstock consumption and without carbon dioxide emissions.    DETAILED DESCRIPTION - The process comprises introducing a solid carbonaceous feedstock and a gas stream into a chamber and then mixing to produce a warm solid-gas mixture comprising a dry solid carbonaceous feedstock, where: the gas stream comprises syngas produced by a gasification reactor (10) comprising a reactor upper section (40) and a reactor lower section (30); and the warm solid-gas mixture is maintained at a temperature of 500-800 degrees F that minimizes the formation of tar when inside the chamber, separating the warm solid-gas mixture in a separating device (50) to produce a separated dry carbonaceous feedstock and a separated gaseous product, passing the separated dry carbonaceous feedstock into the reactor upper section and reacting with a first mixture product from the reactor lower section to form a second mixture product, where a temperature of the second mixture product leaving the reactor upper section is 1500-2000 degrees F, passing the separated gaseous product to a particulate filtering device to separate out a portion of the residual solid fines and particulates, and passing the residual solid fines and particulates separated by the particulate filtering device to the reactor upper section.
