Disclosed is a phosphorus coal gasification reaction device for combined production of yellow phosphorus and syngas, including a stock bin, a mineral aggregate lock hopper, a phosphorous coal gasification reactor, a slag quench chamber and a slag lock hopper. In the phosphorous coal gasification reactor, a drying zone, a dry distillation zone, a combustion zone, a phosphate rock reduction zone, and a slag bath zone are formed from top to bottom. A gas product outlet communicating with the phosphorous coal gasification reactor is installed at a top of the phosphorous coal gasification reactor, two to eight fuel burners are symmetrically arranged on the combustion zone, and an auxiliary burner communicating with the slag bath zone is arranged at the bottom of the slag bath zone. The reactor device can improve the production capacity of the yellow phosphorus, and reduce the emission of CO.sub.2.

A process and apparatus for gasification of biomass. Biogenic residue may be supplied to a heating zone to dry the biomass and allow the volatile constituents to escape to generate a pyrolysis gas. The pyrolysis gas is supplied to an oxidation zone and substoichiometrically oxidized to generate a crude gas. The carbonaceous residue generated in the heating zone and the crude gas is partially gasified in a gasification zone. The gasification forms activated carbon and a hot process gas. The activated carbon and the hot process gas are conjointly cooled. The adsorption process during the conjoined cooling has the result that tar from the hot process gas is absorbed on the activated carbon in the cooling zone. A pure gas which is substantially tar-free is obtained. The tar-enriched activated carbon may be at least partly burned for heating the heating zone and/or the gasification zone.
