Abstract
The invention relates to an oxidation reactor for partial oxidation of a feed stream with an oxygen-containing oxidant stream to give a hydrogen-containing product stream. This partial oxidation may be conducted as a noncatalytic partial oxidation (POX) or as an autothermal reforming (ATR). Useful feed streams here include hydrocarbonaceous streams, but also ammonia-containing streams. According to the invention, the inlet region of the oxidation reactor is configured as a combination of a dome-shaped region with a (frusto) conical region, where the (frusto) conical inlet region merges into the cylindrical section of the oxidation reactor.
Claims14
An oxidation reactor for partial oxidation of a feed stream with an oxygen-containing oxidant stream to give a hydrogen-containing product stream, comprising:
- (a) a pressure-rated reactor shell having a longitudinal axis and consisting of a metallic material, where the reactor shell comprises the following sections along the longitudinal axis:
- (a1) a dome-shaped first section,
- (a2) a frustoconical second section,
- (a3) a cylindrical third section,
- wherein first section has a gastight connection to the second section, and the second section has a gastight connection to the third section;
- (b) at least one protective layer of a refractory and corrosion-resistant material, mounted within the reactor shell;
- (c) a void volume as reaction chamber disposed within the protective layer;
- (d) an inlet for the feed stream, mounted at the pole of the first section, where the inlet is configured as a burner through which the feed stream, the oxygen-containing oxidant stream and a moderator stream can be introduced into the reactor chamber;
- (e) an outlet disposed at an outlet end of the reactor shell, through which the product stream can be discharged.
