| With the development of economy, fossil energy sourse as development’s impetusdried up daily, in particular, petroleum absence stare us in the face. Superimposedeffect of energy and environment promoted human being’s latency era desire onrenewable energy. As only renewable energy of commutable liquid fuel, bioenergy getmore and more recognition daily by world governments and scientists, and it will bean important source for instead of auto fuel.Stable supply of high quality oil has been confronted with challenge badly. Oneof good solution is bio-oil upgrading into automobile fuel. Biomass fast pyrolysisprocess is a major approach for obtaining bio-oil. Compared with stalk based bio-oil,wood based bio-oil has many advantages, such as higher heat value, lower ash, easilerscaleup due to relatively centralized distribution of feedstock. However, high pHvalue and complex components of such bio-oil make it impossible to be used astransport fuel directly. In this paper, we put forward an innovative bio-oil upgradingmethod which integrated with several process, such as complexation extraction andclassification catalytic reforming. This method may overcome metamorphosed directdistillation, but also increase heating value.For optimized and controlled fast pyrolysis process, the dissertation mainlystudied on wood based material pyrolysis action, optimized pyrolysis parameter,pyrolysis production anlysis. It can provide technical support for commercializationand industrial applications.The fast pyrolysis experimental device was designed and constructed, and stagingcatalytic reforming method was proposed. The modern analytical instruments such asgas chromatography and mass spectrometry (GC-MS), thermogravimetricanalyzer(TG-MS〠TG-DSC and TG-FTIR) were used for product compositionanalysis.The results and conclusions in this dissertation are drawn as follow:(1) anempirical model for wood pyrolysis kinetics and a bio-oil combustion kineticsestablished;(2) illustration of pyrolysis reaction products, mainly C6~14alcohols,esters, ketones and ethers, and other substances;(3) Experimental study of woodenbio-oil deacidification by complexation extraction and its kinetics empirical modelpeformed;(4) The study of staging catalytic reforming of bio-oil and bio-oil as auto fuel guideline made. |
