摘　　要：脱硫石油焦渣是炼油厂脱硫后的产物，含有大量的CaSO4和CaO，是一种新型的钙质材料。试验研究利用脱硫石油焦渣取代石灰制备加气混凝土。结果表明，脱硫石油焦渣可以有效降低石灰的用量，当掺入粉料总质量16～19．2％的脱硫石油焦渣时，生石灰的用量可从原来的20％降低至4．8～8％，具有显著的经济效益。Petroleum coke desulfurization residues, refinery products of desuKurization, contains a large amount of CaSO4 and CaO and is a new type of Calcium material. Experimental study on than we use the petroleum coke desulfurization residue to replace the lime to prepare for aerated concrete. The paper investigates that petroleum coke desulfurization residues can effectively reduce the amount of lime, when its content is 16 to 19.2% of the total mass of the powder, That the original proportions of lime is 20% can be reduced to 4.8 to 8%, and has significant economic benefits.
