Recent research progress on production of hydrocarbon-rich bio-oil through catalytic pyrolysis of lignocellulosic biomass
Abstract: The use of renew able energy sources has been becoming increasingly necessary. Biomass is considered to have potential to be used as an alternative energy source. Bio-oil ( or biomass pyrolysis oil) is a green product obtained from lignocellulosic biomass as raw materials using pyrolysis technology. Due to its rich in a variety of chemical and biological active substances,biomass is deemed to the great development potential substitute of petroleum products. The catalytic pyrolysis of biomass is the main w ay to prepare high quality bio-oil. How ever,because of the high oxygen content of bio-oil in the catalytic conversion process,the low selectivity of target products and the easy coking and deactivation of catalysts,its application has been limited. The conversion of the biomass pyrolysis oil to high value products,such as valuable bio-chemicals ( benzene,toluene,xylene ( BTXs) ,etc.) and bio-polymers,has become one of the important topics in recent years. In this paper,on the basis of the introduction of the mechanism of biomass pyrolysis and its reaction pathw ay,it w as review ed that the recent research progress on the production of high quality bio-oil from catalytic pyrolysis of lignocellulosic biomass using catalyst methods ( metal based oxide catalyst, metal salts catalyst,microporous zeolite catalyst,mesoporous zeolite catalyst,etc.) including catalytic pyrolysis mechanism,transformation mechanism of products,and hydrogen donor ( such as tetrahydronaphthalene,methanol, w aste plastic,w aste oil,etc.) including the co-catalytic pyrolysis mechanism. At the same time,the pyrolysis characteristics,product compositions and transformation mechanism of bio-oil into BTXs in catalytic pyrolysis process w ere summarized. The productions of benzene,toluene,xylene ( BTXs) by ex-situ catalytic pyrolysis ( online catalytic upgrading of pyrolysis vapor of biomass) and deactivation of catalysts w ere emphasized. M eanw hile,some problems and their solutions about catalytic pyrolysis technology of lignocellulose biomass into hydrocarbon-rich ( especially BTXs)
