Evaluation of Performance
The performance of the organic molybdenum catalyst of the examples and the comparative examples is evaluated by using straight-run vacuum residuum of a certain factory as a raw material and using a high-pressure reactor. The process conditions are as follows: the reaction pressure is 16MPa, the reaction temperature is 420 ℃, the reaction time is 2.5 hours, the addition amount of the organic molybdenum salt composition is 650mg/kg, and the organic molybdenum salt composition can synchronously complete in-device presulfiding in the heating process due to the higher sulfur content (3.25 wt percent) in the raw oil, and the separate presulfiding operation is not needed.
The properties of the raw materials for reducing slag and the produced oil are shown in Table 1. As can be seen from the table, when the organic molybdenum catalyst described in examples 7-12 is used for processing the raw material for reducing the residue of straight-run distillation, compared with the density and carbon residue value of the raw material, the obtained product oil has reduced 50%, 90% distillation temperature and end point, and simultaneously the saturated component content in the product composition is generally improved, the saturated component content is improved by about 23% at maximum, and the asphaltene content is obviously reduced. The catalyst shows that the organic molybdenum catalyst with high dispersion and good thermal stability has high catalytic activity and strong coke inhibition capability, and is beneficial to the generation of light components. When the organic molybdenum catalyst in comparative examples 1-3 is used for processing the straight-run slag reduction raw material, the oil density of the obtained product is higher, the 50% distillation temperature is higher than that of the products in examples 7-12 by nearly 100 ℃, the saturation fraction in the product is lower than that in examples 7-12 by more than 8%, and the asphaltene yield is obviously improved. This indicates that the comparative sample has poor dispersibility and thermal stability, resulting in lower catalytic activity, lower hydrocracking efficiency of the feedstock, and severe coking during thermal cracking.
