A method for producing an organic substance includes a step of passing a synthesis gas G1 discharged from a gasifier 11 through a gas cooling tower 21 to cool the synthesis gas G1 with water sprayed in the gas cooling tower 21, a step of passing the synthesis gas G1 cooled in the gas cooling tower 21 through a filtration-type dust collector 22 and a step of bringing a synthesis gas G2 that has passed through at least the gas cooling tower 21 and the filtration-type dust collector 22 into contact with a microbial catalyst to generate an organic substance.

Improvements to the gasifier furnace design and process method to facilitate continuous production of mainly H.sub.2, CO and granulated solid from molten liquid or the liquid slag in the presence of carbonaceous material. It is a method of quenching molten liquid and cooling post quenched hot granulated solid which is done within a long horizontal reaction chamber space of the furnace in the presence of C and H.sub.2O. A moving layer of continuously gas cooled granulated solid protects the moving floor underneath by substantially reducing the possibility of heat transfer from the horizontal reaction chamber to such moving floor and its parts and preventing direct contact between the post quenched hot solid granulates and such moving floor. Such moving floor having plurality of gas passages and is disposed above a plenum that receives gas from outside source and uniformly distributes the gas to pass through all the gas passages.

A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; recovering at least part of the raw synthesis gas from the gasification zone and supplying at least part of the recovered raw synthesis gas to a partial oxidation zone; equilibrating the H.sub.2:CO ratio of the raw synthesis gas in the partial oxidation zone to obtain equilibrated synthesis gas; recovering at least part of the equilibrated synthesis gas from the partial oxidation zone and treating the gas to remove impurities and generate a fine synthesis gas; and converting the optionally adjusted fine synthesis gas into the useful product in a further chemical reaction requiring a usage ratio.

Reactor for recovery or recycling of hydrocarbon products from hydrocarbon-containing material by decomposing and gasifying the material in a reactor housing, comprising a gas/particle separator device arranged to separate solid particles accompanying the gas and to return these particles directly to the reactor housing in the opposite direction to axially flowing gasified hydrocarbon products, and/or comprising a rotor shaft with axially running channels which are in flow communication with a coolant, and/or comprising a radial play formed between the periphery of a rotor and the inside of the reactor housing and amounting to at least 3 cm and at most 6 cm.

A method of producing liquid fuel and/or chemicals from a carbonaceous material entails combusting a conditioned syngas in pulse combustion heat exchangers of a steam reformer to help convert carbonaceous material into first reactor product gas which includes carbon monoxide, hydrogen, carbon dioxide and other gases. A portion of the first reactor product gas is transferred to a hydrogen reformer into which additional conditioned syngas is added and a reaction carried out to produce an improved syngas. The improved syngas is then subject to one or more gas clean-up steps to form a new conditioned syngas. A portion of the new conditioned syngas is recycled to be used as the conditioned syngas in the pulse combustion heat exchangers and in the hydrocarbon reformer. A system for carrying out the method include, a steam reformer, a hydrocarbon reformer, first and second gas-cleanup systems, a synthesis system and an upgrading system.

The invention relates to an apparatus for producing syngas, typically from municipal waste. In particular, a gasifier is used in combination with a plasma furnace. The system is configured so that non-airborne char generated in the gasifier is removed from the system prior to delivery to the plasma furnace. This enhances the energy efficiency of the system whilst still yielding excellent yields of syngas.
