摘　　要：脱硫石油焦渣是高硫石油焦脱硫燃烧的副产品,可用于制备新型建筑材料.试验研究了脱硫石油焦渣的化学组成、矿物成分和放热特征.结果表明,脱硫石油焦渣含有48%～60%的CaO和33%～43%的Ⅱ型硬石膏,2min内便可以基本完成水化放热,温度可达90℃.脱硫石油焦渣可取代石灰和石膏用于加气混凝土、蒸压砖和砂浆等多种建材的生产,社会、经济效益显著.The petroleum coke desulfuration residues is a by-product of high-sulfur petroleum coke after desulfuration procedure, which can be used as a kind of new building material. The chemical compositon,mineral constitution and exothermic chemical characteristics of petroleum coke desutfuration residues are researched in the experiment. The result shows that pe- troleum coke desulfuration residues contain the calcium oxide with 48-60 percent and the calcium sulfate Ⅱ with 33-43 percent. The hydration exothermic action of petroleum coke desulfuration can be finished in 2 min and the temperature is about 90 ℃. Petroleum coke desulfuration residues can be used in aerated concrete, autoclaved brick and mortar instead of lime and plaster for social and economic benefits.
