生物质低温热解炭化特性的实验研究
Experimental Study on Low Temperature Pyrolysis of Biomass
摘要
Abstract
The low temperature pyrolysis characteristics of four kinds of biotnass, named rice straw (RS), mulberry branch (MB), poplar branch (PB) and bamboo (BM), were carried out in fixed-bed type or screw-type pyrolysis reactor at pyrolysis temperature of 250～300℃ and residence time of 10～30min. Results indicated that compared with raw biomass, the apparent volume of biomass chars are decreased and shrunk, and their color are more brownish; The values of O/C mass ratio are decreased, and lower heating values increase significantly; Meanwhile, hydrophobic and grindability of biomass chars are also improved remarkably. The mass yield of biomass char decrease with the increasing of the pyrolysis temperature and residence time, and the high pyrolysis temperature is favorable to generate gaseous product. The mass and energy yields of MB and RS chars decrease with the increasing of pyrolysis temperature and residence time, and the energy yield of biomass is always higher than its mass yield at the same pyrolysis condition. The energy density of biomass chars increases with the increasing of the pyrolysis temperature and residence time. Increasing of energy density of biomass char increases with increasing the residence time at lower pyrolysis temperature, however at higher pyrolysis temperature the effect of residence time on increasing of energy density of biomass char is not significant.关键词
