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.
Claims11
A catalyst precursor for a hydrocracking reaction represented by the following Chemical Formula 1, which reacts with sulfur in a heavy oil to produce a molybdenum disulfide catalyst:
- wherein
- R1 to R3 are independently of one another hydrogen, hydroxy, halogen, C1-C30 alkyl, C3-C30 cycloalkyl, C6-C30 aryl, C1-C30 alkoxy, C3-C30 cycloalkyloxy, or C6-C30 aryloxy, and optionally the alkyl, alkoxy, cycloalkyl, aryl, cycloalkyloxy, or aryloxy of R1 to R3 is independently of one another further substituted by one or more substituents selected from halogen, hydroxy, cyano, C1-C30 alkyl, C3-C30 cycloalkyl, and C6-C30 aryl.
A hydrocracking method of a heavy oil, the method comprising:
- mixing a sulfur-containing heavy oil and a catalyst precursor of the following Chemical Formula 1 to produce a molybdenum disulfide catalyst, and performing a hydrocracking reaction of the heavy oil by using the molybdenum disulfide catalyst:
- wherein
- R1 to R3 are independently of one another hydrogen, hydroxy, halogen, C1-C30 alkyl, C3-C30 cycloalkyl, C6-C30 aryl, C1-C30 alkoxy, C3-C30 cycloalkyloxy, or C6-C30 aryloxy, and optionally the alkyl, alkoxy, cycloalkyl, aryl, cycloalkyloxy, or aryloxy of R1 to R3 is independently of one another further substituted by one or more substituents selected from halogen, hydroxy, cyano, C1-C30 alkyl, C3-C30 cycloalkyl, and C6-C30 aryl.
