[Abstract]:The unconventional heavy oil reserves are rich and its utilization value is gradually paid attention. At present, the thermal reaction performance of unconventional heavy oil is seldom studied. In this paper, the thermal reaction performance of oil sands asphalt, catalytic oil slurry and Karamay super heavy oil is evaluated on the heavy oil thermal processing evaluation instrument, which provides a reference for the unconventional heavy oil hot processing. The coking tendency of sand bitumen, the maximum cleavage degree and the stability of residue oil showed that the coking factor of oil sand asphalt was small in 0.68~1.8%, and the maximum cracking degree was between 40~45% and the depth of thermal cracking of oil samples was less than that in this range. The residue could be stratified at 430 C -40min and 450 C -10min. The oil stability is worse, the condensation depth is about 2% at this time. Based on the distribution data of thermal reaction products, the aggregate dynamic model of oil sand asphalt is set up, the prediction deviation of the total cracking reaction model is small, the total condensation and the 390 C component reaction model predict a large deviation. The main reason is that the two reaction of the product is not considered. The tendency of the heat reaction product with the reaction time was analyzed, and the total kinetic model of the catalytic oil slurry was established. The results showed that the coking factor of the catalytic oil slurry was in the 5~13%, the coking tendency was larger, the conversion rate was low at low temperature and the main product was wax oil, and the prediction result of the total cracking reaction model was small and the recombination diversity was small. The deviation of the total prediction results is large. The coking tendency of the super heavy oil in Karamay and the difficulty of cracking are investigated in the experiment. The coking factor is between 5~10% and the coking tendency of the oil sample is moderate. The result of the evaluation method of the cracking difficulty degree of the earlier development shows that the Karamay super heavy oil is more difficult to crack the oil sample. Based on the experimental evaluation above, the conclusion is made. The results show that the coking tendency of the oil sand asphalt is low and the liquid yield is high. It is a good raw material for hot processing. The coking tendency of the catalytic slurry is serious and the conversion rate of pyrolysis is low at low temperature. It is not suitable to be used as the raw material for heat processing. The coking tendency of Karamay super heavy oil is moderate and the oil sample is hard to crack, and the cracking depth should be properly improved as the raw material for heat processing.
