Is the blending of reduced-pressure wax oil with coker wax oil feed considered heavy oil catalytic cracking?
It does not belong to this category. Heavy oil catalytic cracking involves using vacuum residue as a feedstock, or heavy oil that consists entirely of atmospheric residue; the yield of products is low and their quality is poor, but the plants involved have strong adaptability. Both reduced paraffin oil and coker paraffin oil are fractions of oil, resulting from the catalytic cracking of paraffin oil. Another difference between the two is the residual carbon value of the raw materials: the residual carbon value of paraffin oil is low (0.3%~0.5%), while that of residue oil is higher, at 3%~10%. Depending on the processing method used, the residual carbon value of the final raw material can be controlled to range from 1%~3.5% (approximately).
