TL;DR: In this paper, the performance of Al2O3-TiO2 supporting CoMo and NiMo sulfides catalysts was examined in the transalkylation of isopropylbenzene and hydrogenation of naphthalene as well as the HDS of model sulfur compounds, conventional gas oil (GO), and light cycle oil (LCO).

TL;DR: In this paper, the catalytic activities of CoMo and NiMo sulfides supported on Al2O3, and their modifications with P2O5 (3",wt), ZrO2 (20",wt%), and B2O 3 (15",wt%) were observed in the hydrodesulfurization of 4,6-dimethyldibenzothiophene (4,6)-DMDBT) and real feedstocks of gas oil (GO) and light cycle oil (LCO).

TL;DR: In this article, the deactivation of an iron oxide catalyst in residual oil cracking with generation of hydrogen was studied, and it was found that the hydrogen-producing activity of the catalyst declined during consecutive reduction and oxidation cycles.

TL;DR: In this article, a process for processing a sulfur-containing heavy oil, which comprises: in a first zone, catalytically cracking a sulfur containing heavy oil in the presence of fluidized catalyst particles containing about 30 to 60 wt % Fe to convert the heavy oil to a light oil, and partially fixing the decomposed sulfur compounds with the reduced iron contained in the catalyst particles as iron sulfide; in a second zone, contacting the reduced catalyst from the second zone with steam in a fluidized manner to produce hydrogen and hydrogen sulfide, with the iron oxide-containing catalyst

TL;DR: In this article, a process for simultaneously cracking a heavy hydrocarbons to form light oil and producing hydrogen is described, which comprises a first step where steam and heavy HOGs are simultaneously contacted with a catalyst in a reduced state, containing iron in the form of iron oxide, to produce hydrogen, cracked gases and cracked light oils, to convert the reduced state catalyst into an oxidized-state catalyst, and to deposit coke on the catalyst, a second step wherein the oxidized state catalyst with coke deposited thereon is contacted with an oxygen-containing gas to partially
