渣油加氢脱金属催化剂快速评价方法渣油中沥青质、结焦母体及金属卟啉化合物往往使催化剂迅速失活,以致装置停工。为此,需要使用高性能的加氢脱硫催化剂和脱金属催化剂。脱金属催化剂可将渣油中有机金属(如镍、钒)化合物加以分解,并捕捉、容存这些金属,从而保护脱硫...
Rapid Evaluation of Residue Hydrogenation and Demetallation Catalysts Asphaltenes, coking precursors and metalloporphyrins in resid often deactivate the catalyst rapidly, resulting in shutdown of the unit. For this purpose, high performance hydrodesulfurization catalysts and demetallation catalysts are required. Demetallic catalyst can be residue of organic metal (such as nickel, vanadium) compound to be decomposed, and capture, hold these metals, thereby protecting desulfurization ...
