摘要

页岩灰为油页岩及其半焦的燃烧产物，可作为建筑原材料、化工填料和吸附剂等，具有一定的工程应用价值。采用氮气等温吸附/脱附法对油页岩燃烧生成的页岩灰的孔隙结构进行了测量，并对不同升温速率和不同终温所得到的页岩灰的孔隙结构进行了比较，结果表明：如果油页岩在快速升温条件下燃烧所放出的热量能够被周围环境吸收而使得油页岩颗粒温度始终低于其灰熔点温度，所得到的页岩灰的孔容积和孔比表面积较大，适宜工业应用。

Abstract

Oil shale ash

an inorganic byproduct of burning oil shale and retored shale

has a potential use

such as building material

chemical filling material

adsorbent

etc. To obtain oil shale ash with higher porosity

the pore structure of oil shale ash produced by the combustion of oil shale was measured by using the N2 isothermal adsorption/desorption method.As a result of comparison between oil shale ash samples prepared under different combustion conditions in terms of pore structure

the oil shale ash

formed under both higher heating rate and particle final temperature lower than the melting point of oil shale ash

had a larger pore volume and specific surface area and could be utilized in industries.
