A method for preparing a catalyst having one or more noble metals disposed in a relatively homogeneous distribution on a base which includes an inorganic refractory binder and a zeolite. The method provides for uniformly depositing noble metals on the base after it is formed, without unnecessarily displacing desirable nonframework cations, such as sodium, from the zeolite.

Preparation of uniformly impregnated extrudate catalyst

A product of reduced sulfur content is produced in a multiple stage process from a feedstock which is comprised of a mixture of hydrocarbons and includes sulfur-containing aromatic compounds as unwanted impurities. The first stage involves: (1) subjecting the feedstock to alkylation conditions which are effective to convert a portion of the impurities to higher boiling sulfur-containing products, and (2) separating the resulting products by fractional distillation into a lower boiling fraction and a higher boiling fraction. The lower boiling fraction is comprised of hydrocarbons and is of reduced sulfur content relative to the feedstock. The higher boiling fraction is comprised of hydrocarbons and contains unconverted sulfur-containing aromatic impurities and also the higher boiling sulfur-containing products. Each subsequent stage involves: (1) subjecting the higher boiling fraction from the preceding stage to alkylation conditions which are effective to convert at least a portion of its content of sulfur-containing aromatic compounds to higher boiling sulfur-containing products, and (2) separating the resulting products by fractional distillation into a lower boiling hydrocarbon fraction and a higher boiling fraction which contains higher boiling sulfur-containing alkylation products. The total hydrocarbon product of reduced sulfur content from the process is comprised of the lower boiling fractions from various stages.

Multiple stage sulfur removal process

A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and contains organic sulfur compounds as unwanted impurities. The process comprises converting at least a portion of the sulfur-containing impurities to sulfur-containing products of higher boiling point by treatment with an alkylating agent in the presence of an acid catalyst and removing at least a portion of these higher boiling products by fractional distillation. Suitable alkylating agents include alcohols and olefins. In a preferred embodiment, catalytic cracking products which contain aromatic sulfur compounds as impurities are used as a feedstock for the process.

Sulfur removal process

A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and includes sulfur-containing aromatic compounds as unwanted impurities. The process involves separating the feedstock by fractional distillation into a lower boiling fraction which contains the more volatile sulfur-containing aromatic impurities and at least one higher boiling fraction which contains the less volatile sulfur-containing aromatic impurities. Each fraction is then separately subjected to reaction conditions which are effective to convert at least a portion of its content of sulfur-containing aromatic impurities to higher boiling sulfur-containing products by alkylation with an alkylating agent in the presence of an acidic catalyst. The higher boiling sulfur-containing products are removed by fractional distillation.

A collapsed composition is described which is substantially composed of microcrystallites collectively of the formula:

Absorbent and process for removing sulfur oxides from a gaseous mixture

A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and contains organic sulfur compounds as unwanted impurities. The process comprises converting at least a portion of the sulfur-containing impurities to sulfur-containing products of higher boiling point by treatment with an alkylating agent in the presence of an acid catalyst and removing at least a portion of these higher boiling products by fractional distillation. The process can be carried out in a distillation column reactor wherein the acid catalyzed reaction and fractional distillation are carried out simultaneously. Suitable alkylating agents include alcohols and olefins.

Process for removing sulfur oxides or nitrogen oxides from a gaseous

The present invention features the use of a particulate sorbent and a particulate FCC catalyst, which are physically separable, sequentially in the same FCC riser, followed by separation of commingled spent catalyst and sorbent particles from vapors, and the subsequent primary partial regeneration and heat up of spent sorbent particles and catalysts particles in an oxygen deficient burning zone, followed by physical separation of partially regenerated catalyst and sorbent particles, preferably using a cyclonic classifier to effect the separation. This is followed by secondary regeneration of the resulting segregated partially regenerated sorbent and catalyst streams in oxygen rich combustion zones to fully regenerate sorbent and catalyst particles.

A camera/device support platform with improved structure for positioning the camera/device in multiple positions and about multiple axes. The camera/device is supported and counterbalanced in such a manner so as to maintain the mounting platform in a fixed attitude that is typically parallel to the ground. The camera/device, while so supported, can be freely repositioned closer to or farther from the photographed object, in addition to swinging in a vertical arc or a horizontal arc, without the need to move the support platform.

An improved continuous cyclic process for removing oxides of sulfur from a waste gas with a regenerable particulate adsorbent in which hot adsorbent particles pick up SOx in a first fluid transport riser, followed by separation of clean gas from sulfur-contained particles which are then recycled to a desorber in which they are contacted at elevated temperature with a mixture of reducing gas and water vapor for release of sulfur as hydrogen sulfide. The adsorbent particles are then recycled in the process. Means are provided for removing particulates in the waste gas.

Gas/solid contact method for removing sulfur oxides from gases

A method for updating a concentrate of tar sands bitumen containing fine mineral matter and optionally coarse mineral matter in which solvent-diluted bitumen is contacted for a short time in a riser with hot attrition-resistant substantially catalytically inert acid-resistant fluidizable particles, causing a selective vaporization of the lighter high hydrogen content components of the bitumen. The preferred particles are composed of silica-alumina, most preferably a mixture of mullite and crystalline silica or mullite, crystalline silica and an acid-resistant form of alumina. A portion of the heavier asphaltenes and most of the components which contain metals, sulfur and nitrogen remain on the attrition-resistant fluidizable particles. Fine mineral matter in the bitumen feed also deposits on the fluidized particles instead of being carried over with the vaporized hydrocarbon product. The contact material, with deposit, is contacted with a solution of acid to remove the deposit of mineral matter and deposited metals without decomposing the particles of contact material. The heated particles of contact material are reintroduced into the riser for further contact with incoming diluted bitumen charge.

Process for upgrading tar and bitumen

A method for upgrading a concentrate of tar sands bitumen containing colloidal clay in which solvent-diluted bitumen is contacted for a short time in a riser with hot attrition-resistant substantially catalytically inert fluidizable microspheres, causing a selective vaporization of the lighter high hydrogen content components of the bitumen. A portion of the heavier asphaltenes and most of the components which contain metals, sulfur and nitrogen remain on the attrition-resistant microspheres. Colloidal clay in the bitumen feed also deposits on the microspheres instead of being carried over with the vaporized hydrocarbon product. The contact material, with deposit, is passed to a burner provided with high velocity air jets which attrites the colloidal clay away from the microspheres and the material removed by attrition is recovered. The heated microspheres are reintroduced into the riser for further contact with incoming diluted bitumen charge.
