Tar reform

Tar reforming | Biogenic raw materials in hydrogen production

In the production of renewable hydrogen or synthesis gas from biogenic raw materials, tar compounds are formed as a byproduct during the thermochemical conversion in the biomass gasification process. These must be removed in order to enrich the produced bio-synthesis gas with hydrogen or to use the bio-synthesis gas directly in a gas engine for electricity generation.

Development of a fluidizable nickel catalyst for tar reforming

Based on the catalyst technology developed in the EU project MEMBER for the Sorption Enhanced Reforming (SER) process, which produced a fluidizable nickel catalyst with an extremely high specific surface area at high temperatures, a novel tar reforming catalyst was developed for hot gas purification in biomass gasification. C&CS #1050 B is available in a coarser particle size fraction and is designed as a bulk catalyst. Due to its expected high catalytic activity combined with high mechanical strength, this catalyst is advantageously suited for use in catalytic hot gas filter elements. It also enables the removal of dust. Furthermore, tar reforming increases the synthesis gas yield.
