Patent number: 8313641Abstract: The service life and deactivation rate of a reforming catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water causing process upsets in a catalytic reforming process is practically eliminated. The fact that the guard bed material preserves the active metal phase—copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product.Type: GrantFiled: June 2, 2011Date of Patent: November 20, 2012

Publication number: 20090050531Abstract: Disclosed is a method for the production of synthetic fuels, wherein, in a first step, a gas mixture consisting of methanol and/or dimethyl ether and/or another oxygenate and water vapor is reacted at temperatures of 300-600° C. in order to form olefins with, preferably, 268 carbon atoms. In a second step, the olefin mixture thus obtained is oligomerized at an elevated pressure to form higher olefins with predominantly more than 5, preferably 10-20 carbon atoms. According to said method, a) the production of olefins in the first step is carried out in the presence of a gas flow which essentially consists of saturated hydrocarbons which are separated from the product flow of the second step and returned to the first step, and (b) the production of olefins is carried out in the second step in the presence of a flow of water vapor which is separated from the product flow of the first step and returned to the first step.Type: ApplicationFiled: December 1, 2005Publication date: February 26, 2009Inventors: Martin Rothamel, Bernd Ahlers, Matthias Wagner, Harald Kompel, Jurgen Hofmockel

Publication number: 20090050522Abstract: A process for supplementing steam reformation with hydrogen, oxygen and heat from dissociation of hydrogen peroxide (H2O2). Steam reforming suffers from starting the overall system in an endothermic manner which leads to long start times and limited turndown capability in delivering high quality hydrogen. Using a material such as hydrogen peroxide in a controlled manner allows for instant generation of oxygen-enriched steam, an essential state in reforming hydrocarbons. It additionally, offers the opportunity to relieve parasitic power requirements associated with compressing air to reach the O2 density required for the reforming process and eliminates, or minimizes (as a function of overall power system design requirements) post process cleanup of nitrogen-oxides.Type: ApplicationFiled: July 7, 2005Publication date: February 26, 2009Applicant: CBH2 TECHNOLOGIES, INC.Inventors: Jeffrey L.

Patent number: H2244Abstract: A reforming process in which a hydrocarbon feed containing aliphatic hydrocarbons is converted to a hydrocarbon product comprising an increased proportion of aromatics by passage over a reforming catalyst in a sequence of moving bed reactors operating under reforming conditions including moderate hydrogen pressure. The process is applicable when a former fixed moving bed reformer has been converted to moving bed reactor operation with the recycle and other ancillary equipment retained so that moderate pressure (hydrogen partial pressure at least 11 barg) is required, usually with a catalysts such as Pt/Re which tend to exhibit excessive hydrogenolysis activity in moving bed service. The recycle hydrogen stream is split with a portion going to at least one reactor subsequent to the first reactor.Type: GrantFiled: March 22, 2005Date of Patent: August 3, 2010Assignee: ExxonMobil Research and Engineering CompanyInventors: Russell T.
