炼油与化工一体化 有效利用原油资源——从多种化学反应剖析多产石化产品途径

Efficient use of crude oil resource by integration of oil refining and chemical production

介绍了炼油过程中多产石油化工原料的有关工艺技术,从化学结构转化角度阐明了理论依据。由于原油特别是重油中丰富的烷基碳、环烷碳和芳碳资源均能通过一定途径转化为低碳烯碳以及芳碳,其潜在资源超过单纯依靠石脑油所能提供的数量,因而在经济合理和技术可行的原则下尽量提高其转化率成为当前炼油-化工一体化的研究热点。

The production technologies for multiple petrochemical raw materials were introduced with the theoretical mechanism explained by conversion of chemical structures in the refining process.As there are plenty of alkyl,cycloparaffin and aromatic carbon resource,which can be converted to alkene with low carbon numbers and aromatic carbon via certain ways,in crude oil (especially in heavy oil),the potential carbon resource exceeds that naphtha can provides.The improvement in conversion ratio under the conditions of rational economy and feasible technology will be the hotspot of research in integration of oil refining and chemical industry.
