废旧轮胎是能源和有价值的碳氢化合物产品的来源。废旧轮胎在间歇反应器中常压催化裂解。考察了碱性催化剂(氧化镁和碳酸钙)对热解产物的影响。在350℃下催化热解2小时，气液焦与氧化镁和碳酸钙的分配比分别为24.4：39.8：35.8wt%和32.5：32.2：35.2wt%。对所得热解产物的物化性能进行了表征。与碳酸钙催化剂(50%芳烃和25%极性烃)相比，两种催化剂都产生了25wt的脂肪烃，但使用氧化镁后芳香烃增加了55%，极性烃减少了20%。从蒸馏数据和燃料油试验来看，两种催化剂的油馏分均符合现行柴油工业产品规格。
The waste tyres represent a source of energy and valuable hydrocarbon products. Waste tyres were pyrolysed catalytically in a batch reactor under atmospheric pressure. The effects of basic catalysts (MgO and CaCO3) were studied on the pyrolysis products. The distribution ratio of gas, liquid and char with MgO and CaCO3 were 24.4:39.8:35.8 wt % and 32.5:32.2:35.2 wt % respectively at 350 ° C for 2hr catalytic pyrolysis. The physical and chemical properties of the pyrolzed products obtained were characterized. Both catalysts produced 25 % wt of aliphatic hydrocarbons but with the use of magnesium oxide the aromatic hydrocarbons increased (55 %) and polar hydrocarbons decreased (20 %) as compared to calcium carbonate catalyst (50 % aromatic and 25 % polar hydrocarbons). As far as the distillation data and fuel tests are concerned, the oil fractions with both catalysts fulfill the present specifications of diesel fuel commercial products.
