“…Catalytic tar destruction has been studied in biomass gasification systems for more than twenty years (see for example : Mudge, et al, 1981;Ekstrom, et al, 1982;Bridgwater, 1994;Beenakers, 1994;Aznar, et al, 1997;Abatzoglou, et al, 1997;Milne, et al, 1998Milne, et al, , 1999Neeft, 1999. These processes use catalysts to assist in the cracking and destruction of tars.…”

“…This work began in the early 1980s (Mudge, 1981) and has included studies of a wide range of metal-based catalysts including Ni, Ni/Mo, Ni/Co/Mo, NiO, Pt, Ru, on supports such as silica alumina, zeolites, and others (Aznar, et al, 1997;Alden, et al, 1997; and other references above). Many of these metal-based catalysts are used commercially in the petrochemical industry.…”

As a result of environmental and policy considerations, there is increasing interest in using renewable biomass resources as feedstock for power, fuels, and chemicals and hydrogen. Biomass gasification is seen as an important technology component for expanding the use of biomass. Advanced biomass gasification systems provide clean products that can be used as fuel or synthesis gases in a variety of environmentally friendly processes.Advanced end-use technologies such as gas turbines or synthesis gas systems require high quality gases with narrowly defined specifications. Other systems such as boilers may also have fuel quality requirements, but they will be substantially less demanding. The gas product from biomass gasifiers contains quantities of particulates, tars, and other constituents that may exceed these specified limits. As a result, gas cleaning and conditioning will be required in most systems.Over the past decade, significant research and development activities have been conducted on the topic of gas cleanup and conditioning. This report provides an update of efforts related to large-scale biomass gasification systems and summarizes recent progress. Remaining research and development issues are also summarized.

“…According to the literature, the tar removal from the product gas stream by catalytic cracking is one of the most promising methods and it has been investigated for more than two decades [19][20][21][22][23][24][25][26][27][28]. The studies on the catalytic gasification of biomass include the use of catalyst either in the gasifier itself or in separate reactors downstream from the gasifier [29].…”
