Description

[0001] 1. Technical field

[0002] The invention relates to the technical field of coal tar, in particular to a novel coal tar hydrocracking equipment and a preparation method thereof.

[0003] 2. Background technology

[0004] Due to the high nitrogen content and metal content of coal tar feed, low hydrogen content, hydrodenitrogenation is difficult, and the hydrogen consumption required to achieve the target product is high, and the reaction heat release is large, the traditional hydrocracking unit cannot meet the requirements. The invention adopts a two-stage full-cycle hydrocracking technology to process inferior raw materials.

[0005] 3. Contents of the invention

[0006] The object of the present invention is to provide a novel coal tar hydrocracking equipment and a preparation method thereof. The technical solution is: the new hydrogen compressor is connected to the circulating hydrogen compressor through pipelines, the heating furnace is connected to the protection r...
