Catalytic conversion method for increasing cetane number barrel of diesel
A catalytic conversion process uses a catalytic cracking catalyst having a relatively homogeneous activity containing mainly large pore zeolites in a catalytic conversion reactor. The reaction temperature, residence time of oil vapors and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from about 12 to about 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feed stock oil and containing a diesel. The reaction temperature ranges from about 420° C. to about 550° C. The residence time of oil vapors ranges from about 0.1 to about 5 seconds. The weight ratio of the catalytic cracking catalyst/feedstock is about 1-about 10.
