摘　　要：为在高温下实现油页岩的热解油及热解气同时高收率生产,本文提出“热解反应定向调控”技术路线,并开发了红外加热固定床热解反应器验证该技术路线的可行性,考察了不同热解终温下热解产物分布和焦油组成,分析了铝甑分析和红外加热方式对油页岩热解过程的影响。结果表明,在考察的实验条件范围内,红外加热固定床热解气收率随热解终温升高而持续增加,热解油收率在热解终温为700℃时达到最大,为铝甑分析热解油收率的1.39倍。红外快速加热方式能够促进煤中弱供价键断裂并有效抑制高温反应条件引起的挥发分二次反应,热解所得焦油中轻质组分收率随热解油收率增加而增加。In order to achieve simultaneous high yield production of pyrolytic oil and pyrolysis gas of oil shale at high temperature,a technical route of “directional control of pyrolysis”was proposed in this study and an infrared-heated fixed bed was developed to verify the feasibility of the technical approach.By using this novel reactor,the products distributions and compositions of tar from pyrolysis at different temperatures were investigated,and the influence of fisher assay and infrared heating method on the pyrolysis characteristics were further revealed.In the experiment conditions,with the increasing of temperatures,the yields of pyrolysis gas from oil shale pyrolysis in infrared-heated fixed bed continuously increased,and the tar yield could reach 1.39 times of fisher assay tar yield as the pyrolysis temperature was 700℃,respectively.During oil shale pyrolysis,the covalent bond breakage can be greatly promoted by using infrared rapid heating,and the second reaction of volatiles,caused by a high-temperature condition,could be clearly inhibited,thus resulting in an increased yield of light components in pyrolysis tar as the yield of tar was raised.
