Nov 13, 2001 · The use of dolomite as a catalyst in biomass gasification has attracted much attention,,,,,,,,,,,,,,, since it is a cheap disposable catalyst that can significantly reduce the tar content of the product gas from a gasifier. It may be used as a primary catalyst, dry-mixed with the biomass or, more commonly, in a downstream reactor, in which case it is often referred to as a guard bed.
An overview of catalysts in biomass pyrolysis for
Heterogeneous electro-Fenton is an efficient advanced oxidation process for the degradation of refractory organic contaminants in wastewater, and its efficiency is governed by cathodic catalysts. In this work, the Fe, N doped biochar materials (Fe/N/biochar) were synthesized via a simple ionothermal carbonization of biomass and used as a cathodic catalyst for heterogeneous electro-Fenton. The
Biomass. Bio-oil. Biofuel. Catalyst. Deoxygenation. In-situ. catalytic pyrolysis of biomass has been extensively studied in recent years for cost-competitive production of high quality bio -oil. To achieve that, numerous catalysts have been studied to facilitate . in situ upgrading of low grade condensable vapors
Review of literature on catalysts for biomass gasification - ScienceDirect
About 2 m3 of dry gas (at ambient conditions) per kg of daf biomass were obtained by utilising the fresh catalyst at the highest temperature level, with more than 60% by volume being hydrogen. The
Umicore's DNX ® catalyst is designed specifically for high NOx removal in biomass boiler applications and can be customized to fit in any size boiler. The trimodal pore structure of the catalyst provides the highest available activity in addition to excellent resistance to …

Oct 01, 2019 · Ni-based catalysts have been extensively used in the literature for the removal of tar from hot gas in biomass gasification and appeared to be the best catalyst in dry and steam reforming reactions [ 199, 200 ]. Ni has been mostly used as a downstream catalyst for the removal of tar to increase H 2 formation [ 201 ].
