| 20090099006 | ADDITIVE FOR MAXIMIZING LIGHT OLEFINS IN FCC AND PROCESS FOR PREPARATION THEREOF - The present, invention relates to a process for the production of additives for catalysts for fluid catalytic cracking (FCC) based on zeolite that is selective for light olefins, with the aim of increasing the yields, in FCC units, of liquefied petroleum gas (LPG) and light olefins, of high added value, among others propene and isobutene. This invention provides a method of preparation of catalytic compositions, starting from zeolite modified with phosphate and alkaline-earth metal, that leads to the production of an additive with better performance than the additives, of similar compositions, obtained by other methods of the prior art. The process can be regarded as a development in relation to other processes, as it promotes interaction between the zeolite that is selective for light olefins and its activator, reagent “X”. For this, a separate stage is used during the sequence of stages in the preparation. Moreover, the zeolite does not undergo additional treatments such as filtration, washing or calcination after the treatment with its activator. | 04-16-2009 |
| 20090124712 | PROCESS FOR THE PRODUCTION OF HYBRID CATALYSTS FOR FISCHER-TROPSCH SYNTHESIS AND HYBRID CATALYST PRODUCED ACCORDING TO SAID PROCESS - Process for the production of hybrid catalysts formed by mixing two catalysts; one active in Fischer-Tropsch synthesis, the other being bifunctional. Such hybrid catalyst thus formed is active both in hydrocracking and in hydroisomerisation reactions. The present invention in addition provides obtainment of a hybrid catalyst and application thereof conjointly with FT catalysts in Fischer-Tropsch synthesis reactions. The hybrid catalyst of the present invention is capable of producing in conditions typically such as those utilised in Fischer-Tropsch synthesis branched hydrocarbons in diverse bands relating to the products thereof (for example naphtha and diesel), reducing or even eliminating necessity for a subsequent hydrotreatment stage in such synthesis reactions. Utilisation of such hybrid catalysts of the present invention prolongs the operational efficiency and working life of conventional Fischer-Tropsch synthesis catalysts, reducing substantially encapsulation of particles thereof by waxes produced in the hydroprocessing reactions. | 05-14-2009 |

| 20100296633 | Method and Arrangement for Loop Qualification in a Digital Subscriber Line (DSL) System - A method and loop qualification unit for determining loop parameters of a topology of a twisted pair loop for a digital subscriber line system. The parameters are represented by a vector that receives a measurement of a SELT parameter measured at one end of the loop and a measurement of a DELT loop transfer function measured at both ends of the loop. A first model generator generates a first model for the SELT parameter and a second model generator generates a second model for the DELT function based on the loop parameters represented by the vector. A processor then determines the parameters by minimizing the differences between the first model and the SELT parameter, and the second model and the DELT function. The determined parameters are represented by the vector that provides the minimization. | 11-25-2010 |

| 20110161027 | METHOD AND ARRANGEMENT FOR A DIGITAL SUBSCRIBER LINE - The present invention relates to a method and an arrangement based on two-port network (TPN) theory that allows analytically estimating the loop transfer function from open and short-circuited input impedance measurements, e.g. single ended line transmission (SELT) measurements, by utilizing the fact that the line under test (LUT) can be considered reciprocal and by assuming that the LUT is symmetric. Hence, by using the present invention and an estimation of the noise on the line, the attainable bit rate at the customer premises can be determined by means of SELT measurements at the CO. The transfer function of a telephone copper-loop is estimated regardless of its topology by impedance measurements from the CO side. Specifically, such estimation is carried out from the calculation of the transmission parameters of loop, which are expressed only in terms of open and short-circuited input impedance measurements at the CO when reciprocity and symmetry is assumed. | 06-30-2011 |
