-Introduction
Hydrocracking catalyst LHC-60 is developed for producing quality naphtha and clean diesel from
anthracene oil and washing oil both separated from coal tar. The catalyst LHC-60 is combined with guard catalysts, hydrodemetallization (HDM) catalyst, and hydrofining catalyst in several reactors to hydroprocess the mixture of anthracene oil and washing oil. The product is quality naphtha and clean diesel. With this new catalyst, anthracene oil and washing oil from coal tar can be processed to high value products.
-Characteristics
Mild hydrocracking activity
Good selectivity for naphtha and diesel
