Plastic wastes are thermally cracked to give primarily liquid products which are transformed into synthesis gas by partial oxidation.

Process for the preparation of synthesis gas

A burner for the production of synthesis gas by partial oxidation of carbon-containing fuels, which burner contains three or more concentrically arranged tubes and a cooling chamber. The downstream face of the cooling chamber is clad with a layer composed of individual, adjacently arranged, ceramic platelets.

Aqueous solutions which are contaminated by hydrogen sulfide, hydrogen cyanide, and ammonia are brought to a pH of about 3 or less after their formation and treated with an inert gas in a stripping column to remove the sulfide and cyanide. The pH of the solution is then increased to about 10 or more and the solution is again treated with an inert gas in a second stripping column to remove the ammonia.

Process for purification of aqueous solutions containing hydrogen

The present invention describes a process for producing synthesis gas by partial oxidation of carbon-containing particles suspended in water with oxygen at elevated pressures and temperatures of 1000.degree. to 1600.degree. C. Three substance streams are added separately but simultaneously to the reactor. The inner substance stream consists of oxygen or a mixture of oxygen and synthesis gas. The middle substance stream forms a carbon-water suspension, and the outer substance stream carries oxygen or oxygen-containing gases. Due to the fact that these three substance streams intersect at an acute angle, an ideal distribution of the suspension with the gas streams is achieved and an optimum reaction course is ensured. In order to be able to compensate requirement fluctuations during continuous operation, the outlet opening for the carbon-water suspension and the outer gas stream can be correspondingly adapted in a continuous and independent manner.

Process for producing synthesis gas by partial oxidation of coal-water

The invention relates to a process and a device for the discharge of residues of ash-containing fuels occurring during gasification of coal. The hot mixture of residues and water is separated in a separating chamber, whereby the residues enter a lock vessel situated under the separating chamber. The hot water is recycled to the water bath situated under the gasification reactor. After the lock vessel has been filled with residue, the hot water in the separating chamber is cooled or replaced by cold water. The discharge of the residues is pressureless and is effected by a stream of water flowing through the separating chamber into the lock vessel. Separating chamber and lock vessel remain filled with water at all times.
