In a desulfurization process for the removal of organosulfur compounds from a hydrocarbon fluid stream such as cracked-gasoline or diesel fuel wherein a bifunctional sorbent system is employed, surface treatment of the bifunctional sorbent during the use of same for desulfurization results in an extension of the useful life of the bifunctional sorbent prior to the regeneration and reactivation of same for further use in the desulfurization of the hydrocarbon fluid stream.

Desulfurization process

A novel polymerization catalyst system comprising a diluent, a substrate, a nickel compound wherein the nickel is in a zero oxidation state and picolinic acid and a method for making such catalyst system is described. The polymerization catalyst system can be used in a process for the polymerization of polymerizable olefins.

Olefin polymerization

Hydrogen sulfide is removed from a fluid stream containing hydrogen sulfide by contacting the fluid stream under suitable absorbing conditions with an absorbing composition consisting essentially of zinc oxide and silica. Additionally, the absorbing composition may contain binders and may be promoted, preferably with nickel oxide.

Selective removal of hydrogen sulfide over a zinc oxide and silica

A novel composition comprising zinc oxide and at least one metal phosphate that can be effectively used to remove sulfur compounds from a fluid stream by contacting said fluid stream under suitable absorption conditions with this novel composition. Also, a novel method is described for making a composition comprising mixing with zinc oxide at least one metal phosphate followed by the addition of a dilute acid to form a paste or paste like material having a desired consistency for agglomeration.

Sulfur absorbents and process for removing sulfur from fluid streams

The composition of this invention is a silicated zinc oxide that comprises a co-gelled mixture comprising zinc oxide and silica. This co-gelled mixture is used as a sorbent for removing sulfur compounds from sulfur containing fluids by contacting such fluids with the sorbent. The composition can be prepared by a silicating process wherein the composition is manufactured by silicating zinc oxide to form a co-gelled mixture.

Process for removing hydrogen sulfide from hydrocarbon gases using a

A waste material which contains chromium and/or lead impurities is treated by mixing the waste material with diatomaceous earth and/or sodium borate and then heating the mixture in a free oxygen containing gas at about 500.degree.-1500.degree. C., preferably in the presence of steam.

Reduced leaching of heavy metals from incinerator ashes

A novel sorbent comprising zinc oxide and a Group IIA metal silicate. A process for the removal of hydrogen sulfide from a fluid stream that comprises contacting a fluid stream with a novel sorbent. A further feature of this invention includes a novel method for preparing a composition comprising zinc oxide and a Group IIA metal silicate.

Removal of hydrogen sulfide from fluid streams

Impregnated chloride ions are removed from a chloride containing, platinum on zinc aluminate catalyst support in a specific sequence of operations. In the dechlorination steps, the impregnated platinum is first anchored to the zinc aluminate support in a calcining step, and then the calcined catalyst support is washed with a wash medium to remove the corrosive chloride without removing the platinum catalyst.

Preparation of dehydrogenating catalyst

Hydrogen sulfide is removed from a fluid stream containing hydrogen sulfide by contacting the fluid stream under suitable absorbing conditions with an absorbing composition comprising zinc titanate, alumina and silica promoted with a metal selected from the group consisting of phosphorus, tungsten, molybdenum, metals of Group VIII of the Periodic Table, and mixtures of any two or more thereof. An absorbing composition and a process for producing such absorbing composition are also disclosed.

The composition of this invention is a silicated zinc oxide that comprises a co-gelled mixture comprising zinc oxide and silica. This co-gelled mixture is used as a sorbent for removing sulfur compounds from sulfur containing fluids by contacting such fluids with the sorbent. The composition can be prepared by a silicating process wherein the compositon is manufactured by silicating zinc oxide to form a co-gelled mixture.

Cogelled mixtures of hydrated zinc oxide and hydrated silica sulfur

A novel sorbent comprising zinc oxide and a Group IIA metal silicate. A process for the removal of hydrogen sulfide from a fluid stream that comprises contacting a fluid stream with the novel sorbent. A further feature of this invention includes a novel method for preparing a composition comprising zinc oxide and a Group IIA metal silicate.

Adsorbent compositions for the removal of hydrogen sulfide from fluid

Hydrogen sulfide is removed from a fluid stream containing hydrogen sulfide and less than 500 ppm of free hydrogen by contacting the fluid stream under suitable absorbing conditions with an absorbing composition consisting essentially of a base material and nickel oxide. Said base material is selected from the group consisting of zinc oxide and zinc titanate, preferably combined with alumina.
