20090050531 | Method for the Production of Synthetic Fuels from Oxygenates - 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. | 02-26-2009 |
20110313063 | APPARATUS AND METHOD FOR CONDUCTING A FISCHER-TROPSCH SYNTHESIS REACTION - A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production. | 12-22-2011 |
20120157555 | APPARATUS AND PROCESS FOR THREE-PHASE REACTION - A system and process for removing catalyst fines from a gas stream overhead the slurry in a Fischer-Tropsch slurry bubble column reactor. The gas phase at the top of the slurry bubble column reactor containing small amounts of entrained liquid and catalyst particles. The unreacted gases are passed through a demister, which removes larger droplets and catalyst particles. Smaller droplets and catalyst fines are conveyed to a secondary gas cleaner, such as a cyclone, whereby substantially all remaining particles are removed from the gas phase. A particle-containing liquid produced in the secondary gas cleaner can be further subjected to a filtrate cleaning unit to filter out fine catalyst particles and produce a substantially particle-free liquid product stream and a slurry stream of liquid product containing catalyst particles. | 06-21-2012 |

20110197218 | METHOD AND APPARATUS FOR THE AUTHENTICATION OF USERS OF A HYBRID TERMINAL - The invention concerns a method for the authentication of users of a hybrid terminal with a first registration step. The first registration step comprises entry of user identification data, request to enter a personal identification number, forwarding of the personal identification number to a registration server of an authentication apparatus, forwarding of the user identification data, validation of the user identification data, generation of a registration code, and in the event that entry of the personal identification number has not taken place, generation of the personal identification number, forwarding of the registration code to the internet-capable terminal and in the event that entry of the personal identification number has not taken place, forwarding of the personal identification number via a separate connection to the user. The method also comprises an authentication step comprising checking whether a profile file is present on the hybrid terminal, carrying out an authentication in order to establish whether the user is authorized to receive user data from the service provider and/or to send user data to the service provider, or otherwise carrying out an initial authentication and, if necessary, generation and transfer of the profile file. Furthermore, the invention concerns a corresponding apparatus for carrying out the method. | 08-11-2011 |

Furthermore, the invention concerns a corresponding apparatus for carrying out the method. | 09-19-2013 |
20140137223 | METHOD AND APPARATUS FOR AUTHENTICATING USERS OF A HYBRID TERMINAL - The invention relates to a method and an apparatus for the authentication of users of a hybrid terminal comprising generation of a unique registration code, and a profile file, at least one registration step, comprising entry of user identification data, entry and transmitting a personal identification number from the internet-capable terminal to a registration server, transmitting the user identification data of the user from the internet-capable terminal to the registration server, entry of the unique registration code, validation of the user identification data and, in the case that the user identification data correspond to a user reference data record, assignment of the profile file and if the entry of the personal identification number by the user has not taken place, generation and transmission of the personal identification number from the registration server to the user, and an authentication step, comprising checking whether the profile file is present on the hybrid terminal and, if it is present, carrying out an authentication, otherwise carrying out an initial authentication and, if the initial authentication shows that the user is authorised, generation and transfer of the profile file from the authentication server to the hybrid terminal, and after carrying out the initial authentication or the authentication, transfer of a clearance message to at least one of the service providers. | 05-15-2014 |
