  • Catalyst precursor for hydrocracking reaction and method for hydrocracking heavy oil by using same
    Patent number: 11492561
    Abstract: The present invention relates to a catalyst precursor for forming a molybdenum disulfide catalyst through a reaction with sulfur in heavy oil and to a method for hydrocracking heavy oil by using same. According to the present invention, the yield of a low-boiling liquid product with a high economic value in the products by heavy oil cracking can be increased, and the yield of a relatively uneconomical gas product or coke (toluene insoluble component), which is a byproduct, can be significantly lowered.
    Type: Grant
