A catalyst is provided for hydrodeoxygenation and hydroisomerization of paraffins having higher activity. The catalyst contains a molecular sieve, such as SAPO-11, a metal component such as platinum and/or palladium or nickel tungsten sulfide or nickel molybdenum sulfide and a binder such as gamma alumina. The catalyst exhibits a high proportion of weak acid sites and a relatively equal distribution of the metal component on the molecular sieve and the binder.

Selective hydroisomerization catalyst

A de-hydrogenation catalyst and its use in dehydrogenation of hydrocarbons. The catalyst has low cracking activity and comprises gallium or gallium and platinum on an essentially non-acidic and amorphous alumina-phosphate or silica-alumina-phosphate support with an empirical chemical composition of [Al2O3][SiO2][P2O5], wherein Y is between 0 and 0.2 and Z is between 0.01 and 1.1, with a BET surface area above 50 m/g, as measured by N2 adsorption experiment.

Catalyst for propane dehydrogenation to propylene

A fluidized catalytic reactor system cycles from 0.05-5% of catalyst at a time through a rejuvenation unit to be heated in the presence of oxygen to maintain catalyst activity. The use of the rejuvenation unit that may be 2% of the size of the main catalyst regeneration unit allows for reduction in equipment size and in catalyst inventory. The catalyst that is sent to the rejuvenation unit may be spent catalyst but may be partially or fully regenerated catalyst. The rejuvenation unit may be heated by combusting fuel or by hot flue gas.

Regeneration of a dehydrogenation catalyst slip-stream

A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.

High activity and high distillate yield hydrocracking catalysts with intimate interaction between unsupported metal oxide and zeolite

A method of making highly an active mixed transition metal oxide material has been developed. The method may include sulfiding the metal oxide material to generate metal sulfides which are used as catalyst in a conversion process such as hydroprocessing. The hydroprocessing may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

Highly active trimetallic materials using short-chain alkyl quaternary ammonium compounds

A catalyst composition and its use as a dehydrogenation catalyst to increase normal olefin selectivity and reduce undesirable aromatic selectivity. The reduction in aromatic production allows for the elimination of a unit to remove aromatic compounds. The catalyst has a layered composition comprising an inner core, an outer layer bonded to the inner core, the outer layer comprising one or more transition alumina with at least two diffraction angle peaks between 32.0&#xb0; and 70.0&#xb0; 2&#x3b8;, wherein a first diffraction angle peak in that range is at 32.7&#xb1;0.4&#xb0; 2&#x3b8;, a second diffraction angle peak is at 50.8&#xb1;0.4&#xb0; 2&#x3b8;, and having a thickness of less than about 100 microns and having uniformly dispersed thereon said platinum catalyst and at least one promoter metal and having a concentration of the platinum catalyst of from about 0.00006 to 0.0005 gram of the platinum group metal on an elemental basis per meter square surface area of the outer layer.

Dehydrogenation catalyst with minimized aromatic production

A process is provided for producing linear alkylbenzenes with an improved yield from paraffin feed due to the use of a new catalyst that has a reduced selectivity to produce undesired aromatic compounds. In some embodiments, it is now possible to operate the process without including a unit to remove such aromatic compounds which allows for an operator of a plant to make modifications to the process to increase product yield.
