The carbonaceous material comprises carbonaceous material, carbonaceous liquid product, industrial carbonaceous liquid recycle, carbonaceous municipal solid waste, carbonaceous urban waste, carbonaceous agricultural material, carbonaceous forestry material, carbonaceous wood waste, carbonaceous construction material, carbonaceous vegetative material, carbonaceous petrochemical coproducts, carbonaceous coal, plastic, waste plastic, coke oven tar, fiber soft, tires, lignin, black liquor, polymers, waste polymers, polyethylene terephthalate, 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, carbonaceous industrial waste, alcohol production wastes, ethanol coproducts, spent grains and/ or spent microorganisms. In the method of producing syngas: the amount of total oxygen added into the first reaction zone of the gasifier in pounds per pound of total carbon added to the gasifier comprises 1.25-3.5; and the total amount of oxygen added in pounds to the gasifier per pound of total amount of carbon added to the gasifier comprises 1-3. The first reaction zone temperature comprises 650-1450 degrees F and the second reaction zone temperature comprises 1750-3500 degrees F. The carbon to hydrogen mass ratio in at least one of the carbonaceous material comprises 1-20. The carbon to oxygen mass ratio in at least one of the carbonaceous material comprises 1-200. Preferred Method: The method of producing product gas, further comprises treating the product gas at 1750-3500 degrees F in the presence of molecular oxygen to produce a raw syngas comprising carbon monoxide, hydrogen and syngas-carbon. The raw-syngas comprises syngas-carbon (less than 0.5 pound per 1000 standard cubic foot raw-syngas produced). The method of producing syngas comprises adding carbon dioxide gas into the first reaction zone of the gasifier. The method of producing syngas further comprises: subjecting the raw syngas to cooling and cleaning up to produce a clean syngas; contacting the clean syngas with a biocatalyst in a fermentation container to produce an alcohol product mixture. EXAMPLE - Carbonaceous material (coal) containing carbon (64.8 wt%), oxygen (9.2 wt%), hydrogen (4.5 wt%), ash (16.1 wt%) and other (21.5 wt%) was fed to the lower chamber in which air, oxygen-enriched air or pure oxygen was injected at a controlled rate below a grate. Oxygen (12.1 pound-moles) was added to the first zone of the gasifier and oxygen (18 pound moles) was added to the second zone of the gasifier. The lower chamber temperature and oxygen input was controlled such that only incomplete oxidation of carbonaceous material occurs, not complete combustion. The temperature of 750-1450 degrees F was maintained in the lower chamber and temperature of 1400 degrees F maintained in the first stage. The gaseous product from the lower chamber moved to the second stage or upper chamber. Ash was removed from the lower chamber. Pure oxygen was introduced into the upper chamber to raise the temperature to 2250 degrees F. A raw producer gas (also called raw synthesis gas or raw syngas) containing carbon monoxide (67.5), hydrogen (42.7) and other constituents was produced and removed from upper chamber. The steam was injected in the upper chamber. The raw syngas gas was subjected to cooling and cleanup to produce a product syngas. The product syngas was introduced in a bioreactor or fermentor or fermenter to produces alcohols, methanol, ethanol, propanol and/or butanol.
