摘要:
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.
摘要:
An integrated process for converting low-value paraffinic materials to high octane gasoline and high-cetane diesel light is disclosed. The process involves: (1) oxidation of an iso-paraffin to alkyl hydroperoxide and alcohol; (2) converting the alkyl hydroperoxide and alcohol to dialkyl peroxide; (3) converting low-octane, paraffinic gasoline molecules using the dialkyl peroxides as radical initiators, thereby forming high-cetane diesel, while the dialkyl peroxide is converted to an alcohol; (4) converting the alcohol to an olefin; and (5) alkylating the olefin with iso-butane to form high-octane alkylate. The net reaction is thus conversion of iso-paraffin to high-octane gasoline alkylate, and conversion of low-octane paraffinic gasoline to high-cetane diesel.
摘要:
A process for the complete or partial oxidation of hydrocarbons comprises contacting a C1-C8 hydrocarbon and hydrogen peroxide in the presence of a heterogeneous catalyst under conditions suitable to convert the C1-C8 hydrocarbon to at least one corresponding C1-C8 oxygenate product, wherein the heterogeneous catalyst provides confinement and contains both Brønsted-Lowry and Lewis acid centers. Particularly useful catalysts may include, for example, metal-modified ZSM-5 and other zeolites.
摘要:
A reactor which comprises a vessel (1) with a vessel bottom (2), a stirrer (3) arranged in the vessel, an emergency discharge valve (4) arranged in the vessel bottom for emptying the reactor in less than 600 seconds and at least one filtration device (5) arranged in the vessel bottom is suitable for the safe preparation of organic peroxides. The process for preparing an organic peroxide comprises the steps of preparing a solid hydroperoxide in the form of a suspension in the reactor, filtering the suspension through the filtration device (5) arranged in the vessel bottom (2) while retaining the solid hydroperoxide in the reactor and reacting the hydroperoxide with an alkylating agent, an acylating agent or a carbonyl compound.

摘要:
The present invention relates to novel singlet oxygen catalysts useful for the production of specialty chemicals. The catalysts include a core material selected from amine coated polymeric beads, amine coated glass beads and multi-generational dendrimers to which condensed carbon molecules are bonded. These catalysts may in turn give rise to other solid phase heterogeneous catalysts useful for stereoselective or regioselective reactions, by way of non-limiting example.
