Description

Applicable Scope:

coke . yield. RSC-2006 .1 RSC series are bottom cracking FCC catalysts for reducing slurry and s especially applicable for inferior heavy oil with low saturates content and high metal content.

Characteristics:

RSC series have excellent bottom conversion, high light ends yield, low slurry and coke yield and good metal resistance.

Design Philosophy:

RSC series had been developed for cracking heavy oil to reduce slurry and coke yield based on the SOM (silica-dominated matrix) technology platform. The SOM was designed to be easily accessible to the large hydrocarbon molecules by optimizing its porosity. The SOM was prepared with high activity to effectively precrack the inferior feeds which are difficult to crack. The SOM contains some components which can improve its metal tolerance ability. The pore structure, activity and metal tolerance ability of the SOM can be tuned easily to meet the feeds and processing demands by varying its components and preparing process. Some zeolite modification technology , for example, withdrawing aluminum and replenishing silicon technology, cleaning channels technology, optimizing exchange degree and intra­crystal position of rare earth technology, had been applied to RSC series catalysts to ensure their high activity, good thermal and hydrothermal stability and excellent selectivity.
