[Gasification] reducing temp. of gasification

[Anand Karve]

Dear All,
one requires about 700C temperature for making producer gas. This is
generally achieved by burning the feedstock itself, for which one
introduces external air into the reactor. As a result, the producer
gas gets diluted by the nitrogen in the air. If the process can be
conducted in a closed vessel, which is heated from the outside, one
can get combustible gas without all the nitrogen, but heating the
feedstock inside a container cannot achieve the temperature that is
required for producing producer gas, so that what one gets is
primarily tar vapour. Has anyone thought of using a catalyst for
getting pyrolysis gas at say 300 C? It would help me greatly, if such
a catalyst were available.
Yours
