Overview of sinopec zhanjiang dongxing petrochemical application:

The processing capacity of zhanjiang no. 1 catalytic unit is 500,000 tons/year, the raw material is 95% atmospheric residual oil and 5% normal oil, the main products are gasoline, light diesel, liquefied gas. The balanced catalyst storage in the two vessels is about 90 tons. In order to increase propylene production and increase economic benefits, we started to use our light olefins catalyst to increase production in February 2019.

Refueling process: refueling process: based on the actual situation of the enterprise, the refueling process can be divided into three processes: rapid refueling, balanced refueling, and stable refueling. Finally, the maintenance agent accounts for 6% of the system storage.

Application effect: the total yield of gasoline, LPG and diesel oil changed little after losa-100 was used to increase light olefin. The yield of propylene increased by 1.42% relative to the raw material, and the olefin content of gasoline did not change significantly. The production rate of LPG increased, and the alkenes with high utilization value in LPG increased obviously, among which the content of isobutene increased by 0.52 percentage points. At the same time, the octane number of gasoline increased to a certain extent.
