Process of Alkylation of Isobutane with Olefins
20180065900 · 2018-03-08 ·

The process for producing an alkylate is intended for use in the oil refining and hydrocarbon process industry. The process comprises reacting isobutane with an alkylation agent (an olefin) in the presence of a solid acidic catalyst and a C4+ solvent. Thus, a system is obtained, wherein the solid acidic catalyst is suspended in a solvent and the suspension is maintained by passing the feed stream through the catalyst-solvent system, thereby providing a uniform catalyst distribution throughout the entire volume and enabling the reaction to be carried out at low pressures.

High octane gasoline and process for making same

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.

Process of Making Olefins or Alkylate by Reaction of Methanol and/or DME or by Reaction of Methanol and/or DME and Butane
20170113981 · 2017-04-27 ·

Methods of simultaneously converting butanes and methanol to olefins over Ti-containing zeolite catalysts are described. The exothermicity of the alcohols to olefins reaction is matched by endothermicity of dehydrogenation reaction of butane(s) to light olefins resulting in a thermo-neutral process. The Ti-containing zeolites provide excellent selectivity to light olefins as well as exceptionally high hydrothermal stability. The coupled reaction may advantageously be conducted in a staged reactor with methanol/DME conversion zones alternating with zones for butane(s) dehydrogenation. The resulting light olefins can then be reacted with iso-butane to produce high-octane alkylate. The net result is a highly efficient and low cost method for converting methanol and butanes to alkylate.
