| 20090264278 | Method and Apparatus for Addition of an Alkali Metal Promoter to a Dehydrogenation Catalyst - An apparatus and method for adding an alkali metal promoter into steam and contacting the solution with a dehydrogenation catalyst during a dehydrogenation reaction is disclosed. The apparatus has a first conduit capable of transporting an alkali metal salt solution and a second conduit in fluid communication with the first conduit, the second conduit capable of transporting steam so that the alkali metal salt is dissipated into the steam prior to entry into a dehydrogenation reaction zone. | 10-22-2009 |
| 20100022813 | Process for Reducing Ethylbenzene Content from an Aromatic Stream - A method of reducing the ethylbenzene content in a stream containing xylene is disclosed. The method includes the reaction of ethylbenzene, such as a disproportionation or transalkylation reaction, to produce benzene and other hydrocarbon compound and can include the separation of at least a portion of the resulting benzene and other hydrocarbon compounds to produce a xylene stream having reduced ethylbenzene content. | 01-28-2010 |
| 20100041931 | Method for Production of Styrene from Toluene Syngas - A method for the production of styrene comprising reacting toluene and syngas in one or more reactors is disclosed. | 02-18-2010 |
| 20100081855 | Semi-Supported Dehydrogenation Catalyst - A catalyst having at least 5 weight percent of an alumina compound useful for the dehydrogenation of alkylaromatic hydrocarbons to alkenylaromatic hydrocarbons and methods of use are disclosed. | 04-01-2010 |
| 20100167913 | Catalyst with an Ion-Modified Binder - A solid catalyst, such as a molecular sieve catalyst or solid acid catalyst, is supported by a binder, such as amorphous silica or alumina, wherein the binder is charged with metal ions to form an ion-modified binder. The ion-modified binder is capable of attachment to polar contaminants and inhibit their contact with the catalyst. The catalyst can be a zeolite and can be the catalyst for an alkylation reaction, such as the alkylation of benzene with ethylene. | 07-01-2010 |
| 20100168486 | Method for Production of Styrene from Toluene and Methanol - A process is disclosed for making styrene by converting methanol to formaldehyde in a reactor then reacting the formaldehyde with toluene to form styrene in a separate reactor. | 07-01-2010 |
| 20100312029 | CONTINUOUS PROCESS FOR OXYGEN-FREE CONVERSION OF METHANE - A method for dehydroaromatizing methane by contacting a feedstream that contains methane, in a circulating fluid bed reactor/regenerator, with a catalyst and under conditions sufficient to dehydroaromatize methane and produce at least one liquid aromatic compound such as benzene, toluene or naphthalene and hydrogenated products such as cyclohexane and decahydronaphthalene. The method may also be used to produce hydrogen. The feedstream may be a natural gas feedstock. The method may include one step and two step catalyst regeneration. | 12-09-2010 |
| 20110105316 | Mixed Metal Oxide Ingredients for Bulk Metal Oxide Catalysts - A bulk metal oxide catalyst can be prepared by combining metal oxide powders or oxide-producing species and reacting selected ingredients prior to their inclusion in the formulation of the catalyst. Mixed metal oxide phases can be designed and prepared for use as an ingredient for a bulk metal oxide catalyst to alter properties for catalytic performance or physical properties that would not be obtained using mixtures of singular metal oxide ingredients. | 05-05-2011 |
