Title:
GAS TREATMENT APPLIANCE AND GAS TREATMENT PROCESS USING BACTERIA FOR REDUCING TAR
Document Type and Number:
WIPO Patent Application WO/2010/072818
Kind Code:
A3
Abstract:
A gas treatment appliance and a gas treatment process are provided, by means of which the proportion of tar is decreased in a product gas which is formed on the gasification of carbonaceous feedstocks. The product gas or synthesis gas formed on the gasification of carbonaceous feedstocks is generally highly polluted with tar. This tar-polluted product gas is exposed to a solid support substrate which is a support for bacteria which degrade tar. Suitable bacteria therefor are, in particular, bacteria such as occur in biogas-generating processes. The bacteria contained in the solid support substrate convert at least some of the tars and polycyclic aromatic hydrocarbons (PAHs) contained in the product gas into shorter-chain hydrocarbon compounds and methane which are not an industrial problem, and so their proportion is reduced in the product gas leaving the support substrate. In this manner the tar pollution in a synthesis gas or product gas can be reduced in a simple and inexpensive manner.
