A system for combined production of yellow phosphorous and syngas is disclosed. The air separation unit, the pulverized coal preparation unit and the mineral aggregate forming unit are respectively connected to a gas inlet and a top feeding port of the phosphorus coal gasifier; phosphorus-containing syngas obtained from phosphorus coal gasifier is connected to a gas inlet of the separating washing unit through an outlet of the phosphorous coal gasifier; Yellow phosphorus products and crude syngas are respectively output from the output port of the separating washing unit; and then the crude syngas is purified to obtain refined syngas. A slag discharge port at the bottom of the phosphorus coal gasifier is connected to an input port of a slag cold quenching unit. The system can improve the available energy of yellow phosphorous production, the production capacity of yellow phosphorus and the yield of syngas, and reduce CO.sub.2 emission.

Processes and systems for converting a hydrocarbon-containing feed. The feed and heated particles can be contacted within a pyrolysis zone to effect pyrolysis of at least a portion of the feed to produce a pyrolysis zone effluent and a first gaseous stream rich in olefins and a first particle stream rich in the particles can be obtained therefrom. At least a portion of the first particle stream, an oxidant, and steam can be fed into a gasification zone and contacted therein to effect gasification of at least a portion of coke disposed on the surface of the particles to produce a gasification zone effluent. A second gaseous stream rich in a synthesis gas and a second particle stream rich in heated and regenerated particles can be obtained from the gasification zone effluent. At least a portion of the second particle stream can be fed into the pyrolysis zone.

An integrated biomass conversion system and a method of starting and shutting down the system are disclosed. The integrated biomass conversion system comprises a syngas generator, such as a gasifier, a cleanup engine and a syngas utilization system, which could be a power producing engine or a chemical reactor for chemical or fuel synthesis. The cleanup engine operates rich and at high temperatures so that the tars exhausted by the syngas generators are destroyed and not allowed to foul other components. An orderly sequence to start and shut down the integrated biomass conversion system is disclosed.

Gasifiers, gasification systems, and methods for producing synthesis gas are disclosed. A gasifier can include a gasifier body. A feeder can be positioned to feed an organic material into the gasifier body.

The invention relates to the field of gasification of a carbonaceous feedstock and can be used in the chemical, petrochemical, coke-gas and energy industries. A method for gasification of a carbonaceous feedstock comprises partial oxidation of the carbonaceous feedstock in an oxidation chamber in a mixture of oxygen-containing gas and water vapour in a partial oxidation channel, which is mounted coaxially in the vertical oxidation chamber. The water vapour for the partial oxidation of the carbonaceous feedstock is supplied at the input and output of the vertical oxidation chamber of a combustion chamber. A gas producer comprises a housing, a burner device, a vertical oxidation chamber, manifolds for supplying carbonaceous feedstock, water vapour and oxygen-containing gas, a pipe for discharging gasification products, a slag removal chamber, and also a partial oxidation channel, which is arranged coaxially in the vertical oxidation chamber and is attached to an upper internal part of the housing, in which the burner device is installed. What is achieved is the production of producer gas with an elevated concentration of hydrogen.
