|Process for Lignin Conversion to Chemicals or Fuels with H2 Generated from Lignin Depolymerization Products - A process is presented for the production of high value chemicals from lignin. The process comprises combining several internal steps to use the hydrogen generated by the process, rather than adding an external source of hydrogen. The process can combine the decomposition of oxygenates formed during the deoxygenation process with hydrogenation of deoxygenated lignin compounds.
|METHOD FOR PRODUCING COMPOUND - A method for producing a compound according to the present invention includes synthesizing a compound represented by general formula (3): R—Ar
|ALKYLATION PROCESS - The present invention provides an improved process for producing an alkylated aromatic compound from an at least partially untreated alkylatable aromatic compound having catalyst poisons, wherein said alkylatable aromatic compound stream is treated to reduce catalyst poisons with a treatment composition having a surface area/surface volume ratio of greater than or equal to 30 in
|DEVICE AND METHOD FOR ARYL-ALKYL COUPLING USING DECARBOXYLATION - A method for alkylating aromatic compounds is described using an electrochemical decarboxylation process. This process produces aryl-alkyl compounds that have properties useful in Group V lubricants (and other products) from abundant and economical carboxylic acids. The process presented here is also advantageous as it is conducted at moderate temperatures and conditions, without the need of a catalyst. The electrochemical decarboxylation has only H
|Dehydrogenation Process - Disclosed herein is a process for dehydrogenating a saturated cyclic hydrocarbon and/or 5-membered ring compound with a dehydrogenation catalyst. The dehydrogenation catalyst comprises: (i) 0.05 wt % to 5 wt % of a metal selected from Group 14 of the Periodic Table of Elements; and (ii) 0.1 wt % to 10 wt % of a metal selected from Groups 6 to 10 of the Periodic Table of Elements. The process is conducted under dehydrogenation conditions effective to dehydrogenate at least a portion saturated cyclic hydrocarbon and/or 5-membered ring compound.
|System and Process for Making Cyclohexylbenzene - A system for making cyclohexylbenzene starting from benzene and hydrogen includes a first benzene preparation column, a hydroalkylation reactor, a dehydrogenation reactor, a second distillation column for cyclohexylbenzene separation, a third distillation column for cyclohexylbenzene purification, a transalkylation reactor, and a fourth distillation column for separating cyclohexylbenzene from transalkylation effluent. All components are integrated to achieve a high-purity cyclohexylbenzene product produced with a high yield and high overall energy efficiency.
