The present invention provides a process and apparatus for converting feedstock comprising biomass and/or carbon-containing solid waste material to synthesis gas. The process comprises supplying the feedstock to a gasifier comprising a fluidized bed zone and a post-gasification zone and contacting the feedstock with a gasification agent at a plurality of different operating temperatures based on the ash softening temperature of the feedstock and finally recovering the synthesis gas. The apparatus is configured to perform the process and comprises a plurality of nozzles arranged at an acute angle relative to a horizontal plane of the gasifier.

The invention relates to an aftertreatment arrangement () for the aftertreatment of at least gases downstream of a fluidized bed gasification process, in particular downstream of an HTW gasifier () of a pressure-loaded fluidized bed gasification process, having a particle separation unit () which can be arranged downstream of the fluidized bed gasification process and upstream of a gas cooler () that can be used for the further aftertreatment of the gases, wherein the aftertreatment arrangement comprises an intermediate cooling unit () which can be arranged downstream of the fluidized bed gasification process and upstream of the particle separation unit (), having a return (B) for gasification steam (B) that can be coupled to the fluidized bed gasification process. Furthermore, the invention relates to a method for the aftertreatment of at least gases downstream of a fluidized bed gasification process as well as the use of an intermediate cooling unit.

The invention relates to an oxygen lance that has at least three mutually coaxial pipes, each of which delimits at least one annular gap. The outermost pipe is designed to conduct superheated steam and has a steam supply point, the central pipe is designed as an annular gap, and the innermost pipe is designed to conduct oxygen at a temperature of no higher than 180&#xb0; C. and has an oxygen supply point. A temperature sensor is arranged within the innermost pipe, said temperature sensor extending to just in front of the opening of the innermost pipe. The innermost pipe tapers in the form of a nozzle before opening; the innermost pipe opens into the central pipe; and the opening of the central pipe protrudes farther relative to the opening of the outermost pipe.
