摘要：主要研究了竹材在快速热解与常规热解下液相、固相及气相产品的得率差异。快速 热解下升温28℃／s,停留时间0．76 s,温度500℃,液相产品竹焦油得率为48．5％,主要组分 为2,6-二甲氧基苯酚和2-甲氧基苯酚(愈疮木酚),在常规热解下升温速率1℃／min,温度 500℃,液相得率为30％(包括水),组分主要为乙酸。在常规或缓慢热解中,固相产物,炭的 微孔结构中。当热解温度低于550℃的情况下,主要孔径在6．0-22．0 nm,当热解温度在650-750℃,主要孔 径<2 nm。
The characteristic feature of flash pyrolysis and conventional pyrolysis of bamboo were investigated. The operating conditions of flash pyrolysis was ： temperature 500 ℃, residence time of volatile matter 0.76 s and heating rate 28 ℃/s. The yield of the liquid product was 48.5 %, containing 2,6-dimethoxy phenol and 2-methoxy phenol as major constituents. The processing condition of conventional bamboo pyrolysis was： heating rate 1℃/min and temperature 500 ℃. The yield of liquid products including water was 30 %, containing acetic acid as major constituent. In conventinal pyrolysis at temperature less than 550 ℃, the main pore diameters were 6.0 - 22.0 nm. At pyrolysis temperature 650 -750 ℃, the main pore diameters were less than 2 nm.
