Selective liquefaction of wood biomass by pulse current heating

1. Products from fast pyrolysis of wood biomass with pulse current heating Useful products were obtained from bio-oil and char by fast pyrolysis of wood biomass. Developing technology is relevant for the effective utilization of char and for production of chemicals from bio-oil. On the other hand, shape-controlled porous carbon and catalyst carrier are interesting examples of the potential application of pulse current heating method in order to obtain value added products from residue(char) obtained by fast pyrolysis as Kurosaki reported. [1, 2] Fast pyrolysis of wood biomass with pulse current heating was examined in order to get useful co-products from bio-oil and to know the optimum pyrolysis conditions of the compositions in bio-oil and structural properties of the co-products. The maximum yield of bio-oil was obtained at around 500ºC. GC-MS, FT-IR and elemental analysis made clear the effects of reaction temperature on mass balance, chemical structure of bio-oil compositions, the organics and ammonia adsorbed by char [3]. 2. Utilization of Biomass Resources by Selective Liquefaction with Pulse Current Heating Method Pyrolysis conditions and basic components of woody biomass, plant biomass were studied. The composition of products, bio-oil and the characteristic of char were also studied. The effects of pyrolysis temperature on the compositions of products showed that the maximum yield of bio-oil was obtained at 500ºC for rice husks and at 600ºC for cellulose. The effects of pyrolysis temperature on the ammonia adsorption capacity of char was acquired. High amount of levoglucosan was contained in bio-oil at 400-800ºC during pyrolysis of cellulose [4]
