Embodiment 1

[0119] Using Mo(O)(O 2 ) 2 (PPh 3 ) 2 Hydrocracking reaction of

[0120] Step 1. Add 1 g (6.94 mmol) of MoO to a 100 mL Schlenk tube replaced with argon 3 and hydrogen peroxide (H 2 o 2 , 27%) 2ml, stirred at 65°C for about 45 minutes. When the reactant became a yellow transparent solution, the Schlank tube was placed in ice water, and the temperature of the reactant was lowered to 0°C. After the temperature of the reactant was lowered, triphenylphosphine (Triphenylphosphine, 4 g, 15.28 mmol) was dissolved in 10 ml of tetrahydrofuran (THF), and slowly added dropwise into the Schlenk tube. After complete dropwise addition, the reaction was carried out at 0° C. for 1 hour, and at normal temperature (23° C.) for 1 hour. After the reaction, remove the supernatant, wash the precipitate once with distilled water, wash with ethanol and ether for 3 times and then dry it to obtain the catalyst precursor (Mo(O)(O 2 ) 2 (PPh 3 ) 2 ) (yield: 86%).

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.

Description

technical field [0001] The present invention relates to a catalyst precursor which reacts with sulfur in heavy oil to form a molybdenum disulfide catalyst and a method for hydrocracking of heavy oil using it. Background technique [0002] Generally, coke used in the steel industry is produced by dry distillation of raw carbon. At this time, an organic substance with a high carbon ratio and a high boiling point is obtained, which is called coal tar. In order to reuse the generated coal tar, carbon black, naphthalene, pitch, etc. are usually produced through a thermal decomposition process at a high temperature of 1200K or higher. Carbon black, naphthalene, asphalt, etc. thus produced are generally used as tire or cement admixtures. However, such carbon black, naphthalene, pitch, and the like have problems of relatively low added value and limited application range. [0003] Therefore, various researches are being conducted on methods that can further increase the added valu...
