A fluid coking-gasification process for converting heavy hydrocarbonaceous chargestocks to lower boiling products in which a zeolitic material is use to mitigate slagging in the gasifier, especially when the zeolite material is spent catalytic cracking catalyst. The zeolite material is added either directly into the gasifier on it is mixed with the coke passing from the heating zone to the gasification zone.

Integrated coking-gasification process with mitigation of slagging

A catalyst is provided which comprises a phosphorus-treated ultrastable Y-type crystalline zeolite and a non-zeolitic inorganic oxide matrix. A catalytic cracking process utilizing the catalyst is also provided.

Hydrocarbon cracking catalysts and processes for utilizing the same

A rare earth stabilized aluminum deficient zeolite having the structure of faujasite is provided. The zeolite is produced by contacting a Y-type zeolite with a dealuminating agent to remove aluminum from the crystal structure of the zeolite and ion exchanging the zeolite with a specified amount of rare earth metal cations to stabilize the aluminum deficient zeolite.

Rare earth stabilized aluminum deficient zeolite

A catalyst is provided which comprises a crystalline zeolite, discrete particles of phosphorus-containing alumina dispersed in a non-zeolitic inorganic oxide matrix. A catalytic cracking process utilizing the catalyst is also provided.

Co-matrixed zeolite and p/alumina

A phosphorus-containing low alkali metal content zeolitic catalyst made from a clay starting material is provided. The catalyst is obtained by contacting a partially cation exchanged calcined zeolite-containing catalyst with an anion such as a dihydrogen phosphate anion or a dihydrogen phosphite anion and additionally with an ammonium salt other than a salt of an inorganic acid of phosphorus. A hydrocarbon catalytic cracking process utilizing the phosphorus-containing catalyst is also provided.

Catalysts for hydrocarbon treating processes

This invention relates to improvements in a process for the preparation of a magnetic catalyst, particularly a magnetic reforming catalyst. In such process, a Group VIII noble metal is incorporated within an inorganic oxide particulate mass, suitably by impregnation of preformed particles. The metal-containing inorganic oxide particulate mass, in the desired proportion, is then admixed with magnetic alloy particles, notably iron or cobalt, and an inorganic oxide precursor which serves as a binder, to form a particulate composite mass comprised of particles of magnetic alloy dispersed as inclusions within an inorganic oxide matrix.

Process for the preparation of magnetic catalysts

A novel catalyst composition, and process for the preparation of magnetic, catalytic composites to improve catalytic metals utilization. A particulate magnetic alloy of iron or cobalt is contacted with a phosphate ion containing solution and reacted therewith sufficiently to form a surface film thereupon, removed from said solution, preferably dried, then admixed or otherwise incorporated within an inorganic oxide matrix, notably alumina, as inclusions, the composite particle is then contacted with a solution which contains a compound, or compounds, of a Group VIII noble metal, notably platinum, which is deposited within the composite particle in catalytically effective amounts without significant loss of the catalytic metal due to surface deposition of the catalytic metal upon said particulate magnetic alloy inclusions.

Preparation of magnetic catalysts (MSB-06)

A naphtha hydrorefining process is initiated by contacting an olefinic naphtha feed at hydrorefining conditions including a pressure below about 200 psig, with hydrogen and a catalyst that has been partially deactivated by treating a fresh or a regenerated catalyst with a substantially non-metals containing hydrocarbonaceous oil in the presence of hydrogen under conditions sufficient to decrease the hydrogenation activity of the catalyst.

Method for starting-up a naphtha hydrorefining process

Noble metals on supported zeolite-containing hydrocarbon conversion catalysts, which have been at least partially damaged by thermal and/or hydrothermal stresses resulting in a maldistribution of the supported metal, are redispersed to a highly active, high surface area state by contacting said catalyst with ethylenediaminetetraacetic acid (EDTA), or a salt thereof, to the point of incipient wetness and then removing said acid by heat treatment.
