The preparation of oil from pyrolysis of corn stalks has been tested and studied by using a fixed-bed reactor

the influence of reaction temperation

deashing pretreatment

and catalyst etc.upon the distribution of pyrolysis products being mainly investigated.The results of study show that the production rate of pyrolysis liquid from corn stalks is increased at the begining and then decreased along with the temperature rising

the production rate of pyrolysis liquid from original samples is lower than the corresponding production rate of water-cleaned and acid-cleaned samples.Compared with the acid-cleaned corn stalks

the adding of catalyst decreaes the production rate of liquid products.The influence of reation temperature upon the main chemical components and their content in bio-oil isn't substantial.After deashing pretreatment

the content of some small-molecular substances in the bio-oil is reduced.And after adding Na2CO3

the content of small-molecular substances in bio-oil from pyrolysis of acid-cleaned samples is increased.
