US Classification:

502 53

Abstract:

An olefin hydration catalyst is regenerated with a non-oxidizing light gas, such as hydrogen. Light olefins, especially propylene, are converted to a mixture of alcohol(s), such as isopropanol (IPA) and ether(s), such as diisopropylether (DIPE) by contacting a feed containing the olefin with water and/or alcohol with the olefin hydration catalyst. Regeneration conditions include temperatures of from about 150. degree. C. to about 550. degree. C. , pressures below about 1000 psig (6900 kPa). Lower pressures of regeneration unexpectedly demonstrated more effective catalyst regeneration through greater coke removal.

International Classification:

C10G 6908

US Classification:

208 60

Abstract:

An upgrading process for paraffinic naphthas subjects a full range naphtha to hydrocracking over a zeolite beta hydrocracking catalyst to effect a selective, partial hydrocracking in which the higher molecular weight n-paraffinic components of the naphtha are hydrocracked preferentially to the lower molecular weight components with concurrent isomerization of n-paraffins to isoparaffins, to form a hydrocracked effluent which comprises isobutane, C. sub. 5 to C. sub. 7 paraffins and relatively higher boiling naphthenes and paraffins. The hydrocracked effluent is split to remove the isobutane and the C. sub. 5 and C. sub. 7 paraffins with the balance of the higher boiling components being used as a reformer feed. Removal of the C. sub. 5 and C. sub. 7 paraffins permits improved reformer operation with the production of a higher octane product.

International Classification:

C07C 4105
C07C 2904

US Classification:

568695

Abstract:

A method for starting up a fixed bed propylene hydration reactor containing shape selective metallosilicate catalyst particles for the production of isopropanol and/or diisopropyl ether is disclosed comprising the following sequential steps: contacting a feedstream comprising propane with catalyst particles in a hydration reactor; then introducing a feedstream comprising isopropanol into the reactor to displace propane. Next, a feedstream comprising propylene is introduced into the reactor under etherification conditions. Finally, a feedstream is introduced in the reactor comprising water under etherification and hydration reaction conditions whereby diisopropyl ether and isopropanol are produced.

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10G 6910

US Classification:

208 89

Abstract:

A hydrocracking process employing a hydrocracking catalyst based on zeolite beta together with a metal hydrogenation/dehydrogenation component recycles the unconverted, hydrocracked bottoms fraction to the hydrocracking step for improvements in distillate selectivity and denitrogenation without loss of catalyst activity while improving dewaxing of the unconverted bottoms fraction. The process typically operates at low to moderate hydrogen pressures up to 1500 psig (10445 kPa) with low hydrogen consumptions typically below 800 SCF/Bbl (142 n. l. l. sup. -1). Denitrogenation is notably high at 90 weight percent or higher.

Abstract:

A method for conversion of linear C5 olefins in the presence of contaminant diolefins to corresponding iso-olefins of the same carbon number which comprises contacting a linear C5 olefin-containing organic feedstock with a catalyst comprising material having the structure of ZSM-35 under skeletal isomerization conditions, wherein said conversion is carried out at temperatures between about 100. degree. and 750. degree. C. , weight hourly space velocities (WHSV) based on linear C5 olefins in said feedstock between 0. 1 and 500 WHSV, C5 linear olefin partial pressures between 2 and 2000 kPa, and in the presence of hydrogen added in an amount sufficient to enhance linear C5 olefin conversion activity and extend the catalyst life of the catalyst relative to operation without any hydrogen added.
