Characteristics of catalytic pyrolysis kinetics of straw
摘要
Abstract
The properties and reaction kinetics of straw catalytic pyrolysis were investigated using thermogravimetric method. Matching computation was carried out to analyze catalytic pyrolysis of straw with the Coats-Redfern method , through which the apparent activation energy and pre-exponential factors of straw pyrolysis with different catalysts were obtained. The initial temperature and final temperature of straw pyrolysis rose after acid-washing. The pyrolysis curve moved to the higher temperature region because of decreasing straw pyrolysis reaction activity. But when metal salts were added to straw,the pyrolysis curve moved to the lower temperature region because of increasing straw pyrolysis reaction activity. The results indicated that the pyrolysis reaction was enhanced by metal salts. The apparent activation energy of acid-washed straw pyrolysis increased. But the apparent activation energy of straw pyrolysis with potassium,calcium and magnesium ions decreased obviously. The larger the ratio of metal ions,the lower the apparent activation energy of straw pyrolysis.关键词
