Abstract: An ionic liquid as a solvent in the hydration reaction of ?-pinene to ?-terpineol. The ionic liquid is obtained from the reaction of an amine and an inorganic acid. The use of the ionic liquid as solvent favors the selectivity towards the formation of ?-terpineol and once the reaction product has been brought to room temperature, the organic phase can be physically separated from the inorganic one by decantation. The inorganic phase contains the ionic liquid, water and reaction catalyst and can be directly reused for a new reaction batch.

Abstract: A cogeneration system to generate thermal energy in form of hot water, using the system's solar collector directly as an evaporator and a heat exchanger integrated in a thermal tank used as a condenser. A variable capacity expander (turbine) is used and the organic working fluid selection is specific for this application. Thus is provided a technological alternative for the production of electricity and thermal energy using a renewable energy source.

Abstract: The present invention refers to developing and obtaining new composite materials based on rubbers and/or elastomers and/or their recycled can be reused through an in situ polymerization program between the combination of different monomers and/or oligomers type diisocyanate, esters, or organic peroxides cross-linking agent, which in their combination generate a binding agent capable of modifying the intrinsic chemical, thermal, rheological, and mechanical properties in the material and the chains chemical cross-linking originated by the incorporation of organic peroxides which are able to accelerate or decrease the reaction rate.

Abstract: The present invention discloses a treatment for recovering silver from ores containing occluded silver, predominantly pyrolusite, which includes a pre-treatment of the manganese-argentiferous ore with sulfur dioxide produced by roasting elemental sulfur, generating manganese sulphate, and pregnant solution with more than 90% silver recovery.

Abstract: The present invention relates to a synthesis method for unsupported and supported ruthenium base (RuS2) catalysts from a ruthenium complex precursor, which is decomposed and activated by a simple activation process; these steps provide a catalyst with very high catalytic activity, in addition the incorporation of ruthenium complex precursor to a support by methods of incipient and wet impregnating is described; the obtained catalytic activities in this invention are in the order of 100 times the molybdenum sulfide catalyst without support and without promoter, 14 times the industrial supported catalyst, and 5 times the activity of the currently most active commercial unsupported catalyst.

Abstract: The present invention relates to synthesis method of a family of ruthenium sulfide catalysts promoted with an added additional metal, unsupported (M/RuS2) and supported (M/RuS2/support). The obtained catalysts exhibit a high catalytic activity in hydrotreating or hydroprocessing (HDT) of hydrocarbons, mainly hydrodesulfuration, hydrodenitrogenation, and hydrodeoxigenation. The impact of the present invention for application in the commercial context, lies in the high catalytic activity of the obtained catalysts, which is far superior to the existing commercial catalysts, as well as the simplicity of the synthesis method, which will affect the quality of the products obtained in the oil industry, allowing to meet the environmental standards imposed by current legislations.

Abstract: A method for obtaining a promoted molybdenum sulfide catalyst and a promoted molybdenum sulfide added with a nanometric additive. The obtained catalyst exhibits an improved catalytic activity in hydrotreatment reactions, such as hydrodesulfurization, hydrodenitrogenation, and hydrogenation. The invention presents as an advantage, in addition to a low cost composition by their transition metals content, the activation of thiosalts precursor using an environmentally friendly atmosphere.

Abstract: The present invention relates to an apparatus for the continuous production of carbon nanotubes (CNT), as well as the method to carry it out. The apparatus for the CNT synthesis includes: two sets or more of tubes to synthesize in its interior the CNT; a set of nozzles for the same number of tubes that each set has, to feed to the interior of the tubes the precursory chemical compounds of the CNT; a furnace to maintain one of the sets to a suitable temperature to allow the formation of the CNT inside the tubes; a system for the detaching and collection of the CNT formed in the previous stage; and a control system, preferably a PLC (PLC by its abbreviation in English) to program the sequence of activities of the equipment.

Abstract: The present invention provides methods of synthesizing molybdenum disulfide (MoS2) and carbon-containing molybdenum disulfide (MoS2-xCx) catalysts that exhibit improved catalytic activity for hydrotreating reactions involving hydrodesulfurization, hydrodenitrogenation, and hydrogenation. The present invention also concerns the resulting catalysts. Furthermore, the invention concerns the promotion of these catalysts with Co, Ni, Fe, and/or Ru sulfides to create catalysts with greater activity, for hydrotreating reactions, than conventional catalysts such as cobalt molybdate on alumina support.
