摘要

以玉米秸秆为研究对象

采用热重分析仪对经预处理和添加催化剂(DHC-32、Na2CO3、CaO、ZnO、CaCO3)的试样进行热解试验

考察了矿物质对原样、脱灰试样热解特性的影响

并采用一级反应对其相应热解动力学进行了计算分析。结果表明

脱灰生物质和加入催化剂的原样及水洗试样热解焦炭产率增加

而催化剂降低了酸洗玉米秸秆焦炭产率;经过预处理的玉米秸秆热解活化能大于原样活化能;与未添加催化剂试样相比

除了加入CaCO3的玉米秸秆热解活化能略有升高外

其它添加催化剂试样的热解活化能均有一定程度降低。

Abstract

Taking corn stalks as object of study

by adopting thermogravimetric analyser

a pyrolysis test of samples after pretreatment and adding catalysis(DHC-32

Na2CO3

CaO

ZnO

and CaCO3) has been carried out

the influence of mineral metters upon pyrolysis behavior of raw and pretreated samples being observed

and the corresponding dynamic properties of pyrolysis being calculated and analysed by using the first order reaction.Results shows that the char yield rate in pyrolysis of deashed bio-mass and catalyst-added raw and water-washed samples has increased

however

the catalysis make the char yield rate of acid-washed corn stalks to be reduced;the activation energy in pyrolysis of pretreated corn stalks is greater than that of raw samples;compared with samples

in which the catalysts haven't added

excepting the activation energy in pyrolysis of corn stalks

in which CaCO3 is added

has slightly heigtened

the activation energy in pyrolysis of samples

in which other catalyst is added

all have reduced in certain degree.
