Influence of calcination temperature for LaTi_(0.2)Fe_(0.8)O_3 on catalytic pyrolysis of bagasse lignin
|
摘要
LaTi_(0.2)Fe_(0.8)O_3(LTF)was prepared by the sol-gel method,and the effects of calcination temperature on the structure and properties were investigated,A new method of preparing aryl oxygen-containing compounds from bagasse lignin(BL)by the catalytic pyrolysis over LTF was proposed.The results show that LTF has cubic crystal phase and porous structure and its optimal calcination temperature is 800 ℃(LTF-800).In the test for catalytic pyrolysis of BL,with the addition of LTF-800,the yield of liquid product reaches the maximum; the contents of phenolics,guaiacols,syringols,phenylates and furans increase obviously,while those of benzenes,esters and carboxylic acid decrease.The total content of aryl oxygencompounds(including phenolics,guaiacols,syringols and phenylates)in liquid product is more than 74 wt%with the addition of LTF-800,larger than that obtained by single BL pyrolysis(62 wt%).LTF could avoid oxygen-containing functional groups from being excessively destroyed.It has nice regeneration performance by controlled combustion of char even after 5 cycles.
