Pre-Hydrotreating Technologies for FCC Feedstocks

1. Operation Flexibility
Targeting at different types of feedstocks and different product schemes, optimized parameters can be chosen for the maximum benefit from hydrotreating and FCC combination unit.
2. Feedstock Adaptability
Different kinds of inferior oils can be processed, including VGO with high sulfur, deep-drawn heavy VGO, CGO and DAO, etc., thus the technologies present notable advantages in the adaptability of processing gas oil even with very poor quality.
3. Product Specifications
The yield of refined gas oil is over 90 wt% with sulfur content less than 2000ppm or even 1000ppm. Meanwhile some diesel could be obtained.
4. Operating Cycle
The operating cycle is not less than 3 years, and the lifetime of the main catalysts is not less than 8 years.
