在当代科技的迅猛发展下,人类能做出许多的实验来解决复杂的问题。例如:溶剂精制对焦化蜡油和催化裂化的性能的影响就可以通过实验来获得人们想要的结论或者解决问题的办法。这个实验采用糠醛对超稠原油直接延迟焦化蜡油及其与催化回炼油的混合油进行溶剂精制,同时必须进行溶剂精制前后劣质焦化蜡油及其与催化回炼油混合油的催化裂化的反应。这个反应在连续反应——再生催化裂化中型实验装置中进行。这个实验表明:溶剂精制法可以拖出劣质的焦化蜡油中百分之七十八到百分之八十五的氮和百分之三十多的芳烃、胶质还有沥青质,但是是在精制油收率在百分之七十左右的条件下。因此要想让催化裂化反应转化率大幅度提高,需要在劣质的焦化蜡油经过溶剂精制后。精制油的催化裂化反应性能优于渣油催化裂化原料,与渣油催化裂化掺炼后,生焦率下降,产品质量明显改善。
With the rapid development of modern science and technology, humans can make many experiments to solve complex problems. For example: solvent refined coker gas oil and catalytic cracking performance can be experimentally to get the conclusions people want or to solve the problem. In this experiment, furfural was used to solvent refine coking wax oil of delayed supercritical crude oil and its mixed oil with catalytic refining oil. At the same time, it was necessary to conduct the reaction of poor quality coker wax oil and its catalytic cracking with the catalytic oil. This reaction was carried out in a continuous reaction-regenerative catalytic cracking pilot plant. This experiment shows that solvent refining can remove between 78 and 85 percent of nitrogen and more than 30 percent of aromatic hydrocarbons in poor coker gas oils, gums and asphaltenes but is In the refined oil yield about 70 percent of the conditions. Therefore, in order to greatly improve the conversion rate of catalytic cracking reaction, it is necessary to refine the inferior coker gas oil after solvent refining. The catalytic cracking reaction performance of the refined oil is better than that of the residue of FCC oil, and after co-refining with residue FCC, the coke yield decreases, and the product quality is obviously improved.
