Active reformer

摘要

The invention provides an apparatus and method for producing synthetic gas. The apparatus has a pyrolysis chamber (12) for generating synthetic gas, a reformer unit (14), conduit means (22, 24) forming a circulation loop for repeatedly circulating gases between said pyrolysis chamber and said water-gas shift reaction zone and means for adding hydrogen to said gas circulating in said loop by way of a water-gas shift reaction.

主权项

1. An apparatus for producing synthetic gas comprising:
a pyrolysis chamber for generating synthetic gas; a reformer unit, the reformer unit having a chamber defining a water gas shift zone; a conduit structure forming a circulation loop for repeatedly circulating gases between said pyrolysis chamber and said water-gas shift reaction zone in the reformer unit; means for adding hydrogen to said gas circulating in said circulation loop by way of a water-gas shift reaction, wherein the hydrogen adding means include:
a control system for monitoring hydrogen content of the synthetic gas in the reformer unit and controlling the circulation of synthetic gas between the pyrolysis chamber and the water-gas shift reaction zone in dependence thereon; andan injection device configured to inject steam into the synthetic gas in the reformer unit, wherein the control system is operable on the injection device to control the injection of steam into the synthetic gas in dependence on the hydrogen content of the synthetic gas in the reformer unit such that the hydrogen addition means includes interaction between the control system and the reformer unit.
