20110121228 | REVALUATION OF AQUEOUS WASTE STREAMS IN THE PROPYLENE OXIDE/STYRENE CO-PRODUCTION PROCESS - The present disclosure describes a method for the revaluation of aqueous waste streams generated in the propylene oxide and styrene co-production processes. In particular, it discloses a method of reducing the organic contaminant load from a highly contaminated aqueous stream and recovery from said stream of organic compounds that may be recirculated or used as fuel in the co-generation of energy, and which comprises: acidification of said aqueous stream with inorganic acid at a pH less than 4.5; separation of the two resulting phases at a temperature greater than 40° C.; washing of the organic phase produced in the previous step with an aqueous solution of excess acid and separation of the two resulting phases. | 05-26-2011 |

20100115071 | DEVICES AND METHOD FOR GUARANTEEING SERVICE REQUIREMENTS PER USER EQUIPMENT BASIS INTO A BEARER - In scenarios where service requirements are negotiated through a signalling layer whereas the services are carried out through a bearer layer, control rules are created at a control server logically interposed between the signalling and bearer layers. These control rules are based on service requirements received from an entity in the signalling layer, and are installed in an entity in the bearer layer for a bearer established therein. However, not all the service requirements negotiated through the signalling layer can be supported at the bearer layer by any user's equipment. The invention provides for a method and devices whereby the control server can create control rules based on the service requirements received from the signalling layer and also based on capabilities of the user's equipment currently used by the user, and whereby the control rules are installed for a currently established bearer or for a new subsequent bearer further established, depending on these control rules. | 05-06-2010 |

20120015266 | CATALYST FOR A PROCESS FOR OBTAINING HYDROGEN THROUGH REFORMING HYDROCARBONS WITH STEAM, PROCESS FOR PREPARING THE CATALYST AND USE THEREOF IN THE PROCESS - The present invention relates to a catalyst for producing gaseous hydrogen current or hydrogen-rich currents through hydrocarbon reforming with water vapor. Said catalyst comprises at least one support, an active phase and at least two promoting agents, and is characterized in that it is a metal-type-supported solid in which the active phase comprises at least one transition metal chosen from group VIII, and at least one promoting agent chosen from the alkaline-earth or transition metals; and the support comprises at least one mixed oxide with a basic nature, and at least one promoting agent chosen from among the lanthanides group. The invention also has as an object the process for preparing the catalyst, as well as its use in the process for obtaining the hydrogen or hydrogen-rich gas from hydrocarbons, in different operating conditions and using various types of hydrocarbons. The catalyst to which this invention pertains has elevated activity and selectivity toward the gasification of hydrocarbons, as well as a high resistance to various deactivation mechanisms which the catalyst undergoes during the reforming process with water vapor. | 01-19-2012 |
20120156576 | PROCESS FOR THE PRODUCTION OF HYDROGEN BY CATALYZED HYDROLYSIS OF A COMPLEX HYDRIDE, AND FACILITY WITH SEMI CONTINUOUS REACTOR FOR CARRYING OUT THE METHOD - The present invention relates to a process for producing a continuous flow of hydrogen by catalyzed hydrolysis of a complex hydride, which comprises at least adding continuously and at constant rate a fuel solution to a reactor comprising a complex hydride stabilized on a hydroxide on a cobalt boride catalyst that is added in excess inside said reactor. Sodium borohydride is preferably used, the hydroxide is sodium hydroxide and the catalyst is supported on nickel foam. Parameters and optimal conditions to achieve continuous production of hydrogen have been determined, which is essential in the operation of fuel cells. A facility comprising a semi continuous reactor designed to perform the above process, which needs no refrigeration is also an object of the present invention, as well as a washing and reactivation process of a catalyst of the type used in the process mentioned above. | 06-21-2012 |
