A process for producing an aromatic hydrocarbon mixture and liquefied petroleum gas (LPG) from a hydrocarbon mixture, and a process for producing a hydrocarbon feedstock which is capable of being used as a feedstock in the ... 12/07/06 - 20060276679 - Integrated process for the production of olefin derivatives The present invention provides a process for the production of an olefin derivative, which process comprises the steps of: (a) cracking a paraffinic hydrocarbon containing feedstock to produce a first dilute olefins stream comprising both olefins and alkanes, (b) reacting at least a portion of said first dilute olefins stream ... 08/17/06 - 20060183952 - Process for the removal of benzene from gasoline streams A process for producing debenzenized and isomerized complex refinery streams, such as gasoline blending stock, by hydrogenating benzene, contained in a mixed hydrocarbon stream in which for example a reformate naphtha stream containing benzene is hydrogenated with a selective hydrogenation catalyst to convert benzene into cyclohexane and contacting the debenzenized ... 07/20/06 - 20060161033 - Production of propylene employing dimerising ethylene to 1-butene, hydroisomerization to 2-butene and metathesis by ethylene A process for producing high purity propylene comprises: a step for dimerizing ethylene to 1-butene; a step for hydroisomerizing 1-butene to 2-butenes; and a step for metathesis of 2-butenes by ethylene. Advantageously, the ethylene used to produce the 1-butene and ethylene for metathesis derive from a steam cracking unit. To ... 05/11/06 - 20060100469 - Process for converting gaseous alkanes to olefins and liquid hydrocarbons A process for converting gaseous alkanes to olefins and liquid hydrocarbons wherein a gaseous feed containing alkanes is reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid are then reacted over a synthetic crystalline alumino-silicate catalyst, such ... 01/19/06 - 20060014989 - Process for preparring linear alpha olefins A process for the preparation of linear alpha olefins having 2n carbon atoms from linear alpha olefins having n carbon atoms comprising the steps of (a) dimerizing a linear alpha olefin having n carbon atoms in the presence of a dimerization catalyst to produce a linear internal olefin having 2n ... 11/17/05 - 20050256354 - Molecular sieve catalyst composition, its making and use in conversion processes The invention relates to a molecular sieve catalyst composition, to a method of making or forming the molecular sieve catalyst composition, and to a conversion process using the catalyst composition. In particular, the invention is directed to a conversion process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, ... 11/10/05 - 20050250969 - Propylene production A method for forming propylene wherein ethylene is employed as a primary feed material in a combination of steps comprising dehydration, skeletal isomerization, and metathesis to form a versatile product mix that can contain one or more of propylene, gasoline, MTBE, and propylene oxide. ... 11/03/05 - 20050245777 - Process to convert linear alkanes into alpha olefins This invention provides for a process to convert branched or linear alkanes to branched or linear alpha olefins (AO) of the same carbon number. The process comprises the steps of: a) halogenating linear alkanes, branched alkanes, or a mixture of linear and branched alkane to produce a mixture containing primary ... 10/20/05 - 20050234278 - Integrating an air separation unit into an oxygenate-to-olefins reaction system This invention provides an integrated system and process for forming light olefins and polymers from oxygenates, and optionally from natural gas. The integrated system includes an air separation unit, which separates air components into an oxygen stream and a nitrogen stream, and which also forms a compressed air stream. According ... 08/25/05 - 20050187415 - Olefin production from steam cracking using process water as steam The invention includes a process for making olefins. In one embodiment, the process comprises producing steam from a process water comprising organic compounds, wherein the process water comprises at least a portion of a product water from a hydrocarbon synthesis process; feeding the steam comprising some organic compounds and a ... ### FreshPatents.com Support |
