Hydrocracking Catalyst for Maximum Production of Clean Diesel with Low Freezing Point

Hydrocracking Catalyst for Maximum Production of Clean Diesel with Low Freezing Point

1. Introduction
Hydrocracking catalyst LSFC-20 comprises W and Ni as hydrogenation components and molecular sieves as cracking component. The catalyst features Y-type zeolite cracking component. LSFC-20 catalyst has excellent catalytic activity, high diesel selectivity, good stability, high strength, etc, and can be used to obtain a wide range of high quality middle distillates with long-term stable operation.

2. Catalytic activity
(1) Operation conditions: Reaction pressure over 10.0 Mpa, H2/oil ratio over 800:1, LHSV 1.5 h-1, and initial inlet air temperature 375 to 410 degree celsius.
(2) Feedstocks: light diesel oil and heavy diesel oil, coker diesel oil, and crude distillation wax oil.
(3) Product: residual oil yield≤ 20%, liquid yield ≥ 97%, diesel S<10PPm

3. Application
This catalyst has been applied in hydrocracking unit with a capacity of 1.2 million t/a in Daqing Petrochemical Company.
