Common characteristics of catalysts needed in my country

Thread Content

In addition to Guangzhou 1# catalyst, Maoming 1# catalyst and Urumqi 1# catalyst mainly refining wax oil, and Qilu blending partial hydrogenation normal residue, more than 90% is residual oil； Therefore, the development of residual oil cracking catalysts is the mainstream ； Except for a few, the heap ratio ~0.75g/ml can be adapted; except for a few, all have heat extraction facilities; the operation mode is all heavy oil refining, requiring more diesel production, and most Sinopec refineries require more LPG production ； Reducing gasoline olefins and sulfur is a common requirement now and in the future ； There are about 30 sets of staged feeding, and about 10 sets of MIP, as well as DCC and ARGG. Apart from commonalities and a few, the main differences are in: Properties of raw oil, paraffin, intermediate, cycloalkyl, etc., metal content and amount, CGO blending and amount, etc. ； Product structure requirements, gasoline/diesel/LPG, octane number, olefin and sulfur device bottle diameter, regeneration heat, air compressor, fan, absorption stability, fractionation system used catalysts and their performance
