摘要
随着经济和社会的快速发展,人类正面临着巨大的能源与环境压力。当今的能源主要来自矿物燃料,矿物能源的应用虽然推动了社会发展,但其过量的使用已引起了日益严重的环境问题。因此,开发和寻求一种新的、清洁、环保的可持续能源已经成为人类社会要解决的重大问题之一。生物质能源是可再生能源的重要组成部分,是唯一可存储和运输的可再生能源,因此它必将成为未来最重要的一种可替代能源。我国生物质资源十分丰富,但是这种宝贵的生物质资源只是简单的燃烧利用,没有进行其它工业转化利用,大量生物质能源被浪费,因此利用生物质能源并将其转化成清洁液体燃料不仅可以缓解能源压力,还可以实现资源综合利用,促进经济发展。
本文主要研究生物质快速热解过程中的各工况参数对生物油的影响,以热解产物种类和含量作为指标探究生物油的性质。通过对不同热解温度和热解时间的研究,得到了三种生物质热解的最优热解条件。若以CO2含量低、醛***和芳香含量高为择优标准,则三种生物质最佳热解条件为:葵花秆:热解温度为600℃,;小麦秆:热解温度为300℃,;玉米秆:热解温度为500℃,。若以CO2含量低、烃类含量高为择优标准,则三种生物质最佳热解条件为:葵花秆:热解温度为600℃,;小麦秆:热解温度为300℃,;玉米秆:热解温度为500℃,。

ABSTRACT
With the rapid development of economy and society, mankind is facing huge energy and environmental pressures. Today's energy mainly from fossil fuels, including coal, oil, natural gas. Although the application of fossil energy to promote social development, but its excessive use has caused increasingly serious environmental problems. Therefore, the development and the search for a new, clean, environmentally sustainable energy has e a human society one of the major problems to be solved. Biomass is an important renewable ponent is the only storage and transportation, renewable energy, so it will e the most important type of future alternative energy. China's biomass resources are very rich, but this precious resource biomass burning simply use no other industrial transformation and utilization of a large number of biomass energy is wasted, so the use of biomass energy and convert it into clean liquid fuels can not only relieve energy pressures, but also can prehensive utilization of resources, and promote economic development.
This paper is mainly used to investigate and explore the fast pyrolysis of biomass in each of the working parameters of the bio-oil, pyrolysis products to the type and content a
