Abstract: The properties of 19 kinds of alkylates produced by different processes were tracked and analyzed, the results indicated that alkylates had high octane number, zero aromatics, low levels of olefin, and oxygen. It is important for plants to focus on the influence factors of alkylates, including octane number; initial distillation point, saturated vapor pressure, level of sulfur and olefin, because these factors affect the performance of blended gasoline. A typical alkylate was selected as a blending component for China VI gasoline. The performance of blended gasoline was verified. On the basis of these data, a first-class enterprises standard of alkylation oil -Isooctane component- (Q/SH PRD 0753-2019), was formulated. The procurement, production and sales units of alkylates can be benchmarked to ensure that the quality of alkylated oil meets the blending requirements for China VI gasoline.
