摘要:

生物质快速热解液化技术的研究已经取得了较大进展,但是在工艺技术上仍然存在生物质转化不完全、生物质利用率不高,有些生物质原料热解获得的生物油组成复杂、热值较低、不能直接利用等问题;同时生物质快速热解液化技术理论研究滞后,制约了该技术水平的提高和发展。我国生物质快速热解液化技术的研究起步较晚,建议加大资助力度以缩小与欧美等发达国家的差距。

Abstract:

The liquefaction technologies of fast pyrolysis of biomass have obtained great advances in the recent years.However,there are some drawbacks in the technologies such as incomplete conversion of biomass, low using rate of stocks,complex components and low caloric values of bio-oil and difficultly direct utilization.At the same time, the study on mechanism of biomass liquefaction of fast pyrolysis also lags,which limits the progress and promotion of the technologies.As a result,the theory studies can not efficiently instruct the practical project application.Our country starts relatively late in the liquefaction technologies of fast pyrolysis of biomass.Therefore,for reducing the difference to occident,it is important to increase the investment in liquefaction technologies of fast pyrolysis of biomass.
