Abstract: A method of producing a catalyst can include heating a hydrotalcite above a decomposition temperature, forming a decomposed hydrotalcite in response to the heating, combining the decomposed hydrotalcite with a metal salt to form a catalyst mixture, and heating the catalyst mixture to convert the metal salt to a metal oxide. The resulting metal oxide combined with the decomposed hydrotalcite forms the catalyst.

Abstract: Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking, fluid catalytic cracking and conversion of naphtha to chemical rich reformate. Feeds to the mixed feed steam cracker include light products from hydroprocessing zones within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline and FCC naphtha aromatics extraction zone within the battery limits. Chemical reformate from straight run naphtha streams is used as an additional feed to the aromatics extraction zone and or the mixed feed steam cracker.

Abstract: A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an α,β-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is α,β-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C2-C4) feedstocks instead of hydrogen (H2).

Abstract: A process for converting light paraffins to a high octane gasoline composition is disclosed. The process involves: (1) oxidation of iso-paraffins to alkyl hydroperoxides and alcohol; (2) conversion of the alkyl hydroperoxides and alcohol to dialkyl peroxides; and (3) radical coupling of iso-paraffins using the dialkyl peroxides as radical initiators, thereby forming gasoline-range molecules. Fractionation of the gasoline-range molecules can then be used to isolate high octane gasoline fractions having a road octane number [(RON+MON)/2] greater than 110.
