干馏

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是：以空气为气化剂的气化方式，得到的气体N_2和焦油含量高，热值一般在5000kJ/Nm~3左右；流化床气化工艺操作复杂，推广应用存在较多困难；直接干馏热解，虽气体的热值高（14000kJ/Nm~3），但产气率低（0.35m~3/kg）。

The results can be helpful to local semicoke production and technology development.
