Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
13 words
The process of claim 1 where the feed stream is a petroleum resid.
Claim 2
Dependent Claim
19 words
The process of claim 1 where vapors of recovered catalyst are condensed on a fluidized bed of comminuted coal.
Claim 3
Dependent Claim
123 words
A process for treating a petroleum resid comprising the steps of: a. hydrogenating in a hydrogenation unit a liquid resid feed intimately mixed with finely divided, unsupported molybdenum oxide catalyst, b. separating a residual stream containing spent catalyst from volatile hydrogenation products, c. feeding said residual stream together with steam and oxygen to a partial oxidation reactor operated at about 1,500* to 2, 700*F. where hydrocarbons are converted primarily to CO and H2 and where said molybdenum catalyst is regenerated to MoO3 and said MoO3 is vaporized, d. quenching the exit gases from said partial oxidation reactor with liquid reside feed to condense vaporized MoO3 to solid MoO3, and e. feeding the resulting liquid resid containing intimately mixed MoO3 to said hydrogenation unit.
Claim 4
Dependent Claim
115 words
A process for treating coal comprising the steps of: a. hydrogenating comminuted coal in a fluidized bed hydrogenation unit employing as catalyst finely divided molybdenum oxide deposited on the surface of said coal, b. separating residual solids of char-catalyst combination from volatile hydrogenation products, c. feeding said residual solids together with steam and oxygen to a partial oxidation reactor operated at about 1,500* to 3, 000*F. where hydrocarbons are converted primarily to CO and H2 and where said molybdenum catalyst is regenerated to MoO3 and said MoO3 is vaporized, and d. feeding the exit gases from said partial oxidation reactor to said hydrogenation unit to condense said vaporized MoO3 on the surface of said coal.
