A solid combination of elemental sulfur and an inorganic support material prepared in an inert atmosphere to provide a composition for absorbing trialkyl arsines. The composition prepared thereby and the method for absorbing trialkyl arsines using the composition.

Supported sulfur compositions and the preparation and use thereof

A composition comprises at least one inorganic oxide and an oxygen-containing metal compound selected from the group consisting of a metal hydroxide, a metal oxide, and combinations of any two or more thereof. The composition can be optionally supported on a support such as an alumina. A process for producing mercaptans comprises contacting an alcohol with hydrogen sulfide in the presence of the composition under a condition sufficient to produce a mercaptan.

Compositions comprising inorganic oxide and process for producing

A sorbent composition is provided comprising: (a) a zinc component; (b) a colloidal oxide component; and (c) a metal oxide component. This sorbent composition can be subjected to a steaming treatment that improves its sulfur loading capability.

Sorbent compositions containing zinc subjected to a steam treatment

A catalyst composition is prepared by a method comprising impregnating alumina with at least one platinum compound, followed by treatment with at least one organoaluminum chloride (preferably ethylaluminum dichloride), titanium tetrachloride and at least one chloroalkane (preferably carbon tetrachloride). The thus-prepared catalyst composition is employed in the isomerization of saturated C.sub.4 -C.sub.8 hydrocarbons (alkanes and/or cycloalkanes), preferably n-butane.

Isomerization catalyst and use thereof in isomerization of saturated

A catalyst composition is prepared by a method comprising impregnating alumina with at least one dissolved titanium compound (preferably a triethanolamine titanate) and at least one platinum compound, followed by treatment (at specific temperature conditions) with at least one organoaluminum chloride (preferably ethylaluminum dichloride), hydrogen chloride and at least one chloroalkane (preferably carbon tetrachloride). The thus-prepared catalyst composition is employed in the isomerization of saturated C.sub.4 -C.sub.8 hydrocarbons (alkanes and/or cycloalkanes), preferably n-butane.

Hydrocarbon isomerization catalyst and use thereof

A process for converting catalytic cracking catalyst fines to a shaped composition comprises acid-treatment of catalytic cracking catalyst fines, followed by separation and drying of the acid-treated fines; preparing a shapable mixture by mixing the dried catalyst fines with calcium aluminate, sodium silicate, phosphoric acid and water; shaping (preferably extruding) the obtained shapable mixture; and drying and thereafter calcining the obtained shaped particles. A shaped composition having high crash strength is obtained by this process.

Binding and shaping of cracking catalyst fines

Solid waste material which contains arsenic and/or mercury impurities is encapsulated in a cured polysulfide polymer so as to alleviate leaching of arsenic and/or mercury into aqueous liquids. Preferably, the solid waste material is first extracted with an alcohol such as ethanol or, alternatively, treated with an oxidizing agent such as aqueous hydrogen peroxide and then substantially dried before the encapsulation with the polymer is carried out.

Reduced leaching of arsenic and/or mercury from solid wastes

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 process for dehydrogenating C.sub.2 -C.sub.8 alkanes in the presence of steam and a catalyst composition containing zinc aluminate, a tin oxide and platinum, wherein the zinc aluminate support material has been prepared by calcining zinc oxide and a hydrated alumina (so as to alleviate coking during the dehydrogenation process).

Alkane dehydrogenation

Catalyst supports, catalyst systems, methods for the preparation thereof, and dimerization process therewith are provided catalyst supports are extruded from a thick paste of potassium carbonate and water catalyst systems comprise at least one elemental alkali metal deposited on the catalyst sypport. Optionally, the catalyst system further comprises at least one promoter.

Process for preparing carbonate supports and catalysts

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

A spent metal contaminated zeolite-containing catalytic cracking catalyst composition is reactivated by a process which comprises contacting with an aqueous solution of at least one carboxylic acid (preferably at least one of formic acid, acetic acid, citric acid and lactic acid). The thus reactivated catalyst composition can be employed in a catalytic cracking process.
