Description

technical field

[0001] The invention relates to the field of petroleum resin hydrogenation, in particular to a micro-interface reaction system and method for petroleum resin hydrogenation. Background technique

[0002] Petroleum resin is an important basic chemical raw material and one of the important organic chemical products that has developed rapidly in recent years. Since C9 petroleum resin contains high unsaturated bonds, it is easy to react under the action of oxygen and other chemical substances, which greatly limits the application of petroleum resin, so it is necessary to carry out hydrogenation treatment on petroleum resin.

[0003] The relative molecular weight of C9 petroleum resin (200-3000) is relatively large. Usually, under the catalysis of high-activity catalysts, the operating conditions reach 10-20MPa and 230-300°C to achieve better hydrogenation effect. In addition, there are toxic impurities such as sulfur and nitrogen in C9 petroleum resin, and the ca...
