Power generation by biomass fuels gasification and its comprehensive utilization is a rising industry. Our company specially recruit Mr. Guo Dezhang, expert and patent owner in this field, to research and design newly type complete set of equipment of biomass gasification power generation in order to reduce the fuel cost for the users and improve the efficiency of energy exchange. According to users needs, safe and reliable computerized controlling system can be designed. For the ash residue of the burned materials, it can be used to produce white carbon black, activated carbon and machine carbon, which can make comprehensive use of recycling energy and helpful to harmonious development of human being and nature.

Producing fuel alcohol via hydrolysis of lignocellulosic biomass leaves a considerable amount of residues waiting for treatment. A study was carried out on the preparation of hydrogen via catalytic gasification of residues from biomass hydrolysis with a novel Ni/modified dolomite binary catalyst, which was prepared by a two-step coprecipitation method and proved available for hydrogen production in terms of both activity and strength. The effects of four operation parameters, that is, the fluidized bed temperature, the catalytic fixed bed temperature, the particle size of the catalyst, and S/B (i.e., the mass ratio of steam to biomass material fed into the fluidized bed per unit time), on hydrogen yield were investigated. The results indicate that hydrogen yield increases with an increase in the temperature of either the fluidized bed or the downstream catalytic fixed bed or the S/B ratio or a reduction in the particle size of the catalyst. The optimum range for each of the four operation parameters from a comprehensive consideration is as follows: 800-850 °C for both the fluidized bed temperature and the catalytic fixed bed temperature, 1.5-2 for the S/B ratio, and 2.0-3.0 mm for the particle size of the catalyst. Furthermore, the gas product from catalytic gasification of residues from biomass hydrolysis contains less CO and CO2 and has a higher H2/CO ratio compared with that of the sawdust. The hydrogen yield of the former is also much higher than that of the latter. These suggest that residues from biomass hydrolysis are an even better gasification material than the original sawdust. This paper provides a novel effective method for modifying the calcined dolomite, which endows the catalyst with satisfactory strength while retaining high activity, and opens a new promising way for utilizing the residues from biomass hydrolysis.

Calcined dolomite is a good catalyst in terms of its activity for gasification of residue derived from biomass hydrolysis for hydrogen production, whereas its fragility can cause trouble during operation. A novel modification method aimed at improving the strength of the calcined dolomite has been presented using magnesium nitrate as the modifier, which was introduced into the dolomite via a co-precipitation process. The strength of the modified dolomite can be up to 250 times as high as the unmodified one and can cause much less bed pressure drop and catalyst loss, though the activity is slightly lowered after modification.
