NOVELTY - Reducing content of tar in a tar containing syngas, comprises: contacting the tar containing syngas with a molecular oxygen containing gas (120) in a first reaction zone (200) to produce a gas mixture; and passing the gas mixture through a heat treatment zone (300) maintained at 900-2000 degrees C for a contact time of 0.5-5 seconds, where at least a portion of the tar undergoes at least partial oxidation and/or cracking to produce a hot syngas, and the gas mixture from the first reaction zone changes direction of flow by impingement on a surface.    USE - The method is useful: for reducing content of tar in a tar containing syngas; for conditioning of producer gas or synthesis gas or syngas; and for gasification of carbonaceous materials (carbonaceous liquid product, carbonaceous industrial 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 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, 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 and/or spent microorganisms) to produce producer gas or synthesis gas or syngas.    ADVANTAGE - The method reduces the tar content of the syngas by at least 10% and provides the hot syngas having less than 10 ppm tar equivalents, where the tar equivalents are equivalent to a hydrocarbon comprising benzene and/or alcohol.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) producing hot syngas comprising treating a carbonaceous material (110) with a molecular oxygen containing gas and optionally with at least one steam and carbon dioxide in a gasification zone (100) to produce a tar containing syngas, passing the tar containing syngas and a molecular oxygen containing gas through a first reaction zone to produce a gas mixture and passing the gas mixture through a heat treatment zone maintained at 900-2000 degrees C for a contact time of 0.5-5 seconds, where at least a portion of the tar undergoes at least one partial oxidation and cracking to produce a hot syngas, where the gas mixture from first reaction zone changes direction of flow by impingement on a surface;    (2) a tar removal apparatus for reducing content of tar in a tar containing syngas to produce a hot syngas, comprising a first reaction zone, where molecular oxygen is introduced and mixed with the tar containing syngas to produce a gas mixture and a heat treatment zone for thermal treatment of tar contained in the gas mixture, where the gas mixture from first reaction zone changes direction of flow by impingement on a surface and the heat treatment zone provides a contact time of 0.5-5 seconds; and    (3) a syngas production apparatus comprising a gasification zone where a carbonaceous material is contacted with molecular oxygen and optionally contacted with at least one of steam and carbon dioxide to produce a tar containing syngas, a first reaction zone where molecular oxygen is introduced and mixed with the tar containing syngas to produce a gas mixture and a heat treatment zone for thermal treatment of tar contained in the tar containing syngas oxygen mixture, where the tar containing syngas oxygen mixture from first reaction zone changes direction of flow by impingement on a surface and the heat treatment zone provides a contact time in 0.5-5 seconds.
