Abstract
To produce ultra-clean fuel, a well-designed composite support, the unique combination of titanosilicate ETS-10 and aluminophosphate AlPO4-5 with alumina, was firstly developed. Compared with pure alumina, it owns a certain amount of B type acid sites of moderate acid strength, contributing to the removal of refractory 4,6-DMDBT effectively. Moreover, it can impede inactive nickel spinel formation, improve metal-support interactions and favor more polymeric tungsten species formation, which facilitates the promotion effect of nickel on tungsten. With FCC diesel (sulfur: 960.0 μg gâ1 and aromatics: 51.0 vol.%) as feed, the clean diesel product (sulfur: 2.7 μg gâ1 and aromatics: 15.0 vol.%) without much over-cracking fractions, can be obtained over the composite support based catalyst, at 8.0 MPa, 633 K, LHSV of 1 hâ1, H2/oil ratio of 500 (v/v).
