摘要
利用WGR-1型精密微电脑量热计系统地测量了20种催化裂化原料油(10种减压蜡油.10种常压渣油和减压渣油)的恒容燃烧热,并实验测定了其相应的物理化学性质参数.根据物理化学原理推导了催化裂化原料油恒容燃烧热与恒压燃烧热的换算模型.用基于此模型的计算机软件和20种催化裂化原料油恒容燃烧热的实测数据,电算出这20种催化裂化原料油的恒压燃烧热.考虑了酸生成热、体积功等因素的影响.给出了催化裂化原料油恒容燃烧热与恒压燃烧热差值的实际数据.最后,用逐步回归方法得到催化裂化原料油恒压燃烧热与其物性(元素组成、密度、分子量、恩氏蒸馏参数)的关联式.相对于实验值的平均偏差在0.2％以内.可以满足一般工程计算的要求.
The combustion heat under constant volume (Qv) of twenty FCC feed stock samples were measured with WGR-1 microcomputer calorimetry. Some related physical chemistry properties are also determined. A new model of calculating the. combustion heat under constant pressure (Qp) from Qv was developed based on the Law of State Function. The calculation results showed that the difference between Qp and Qv was approximately 100 J/g. Correlation of Qp with physical chemistry properties was also developed, and satisfactory results with relative accuracy of 0. 2% were obtained.
