摘要:The present invention provides a one-pot process of synthesis of phenyl naphthalene compounds that are employed as heat transfer agents. More particularly, the present invention provides a process of preparation of 1-phenylnaphthalene and 2-methyl-1-phenylnaphthalene using refinery spent catalyst. These molecules are known for application as synthetic heat transfer fluids that deliver outstanding performance and thermal stability at continuously high operating temperatures. The reaction is carried out in aqueous medium using a spent catalyst which is a palladium based charcoal catalyst as obtained from various refinery processes. Further, the present invention provides a heat resistant formulation using the synthesized polyhydrocarbons, wherein the formulation is optimized with a free radical scavenger.

摘要:This invention is a membrane which is useful for the synthesis of hydrogen peroxide from hydrogen and oxygen. The membrane has a hydrogen contact side and an oxygen contact side and comprises a porous hydrophobic catalyst layer facing the oxygen contact side and a gas flux control layer facing the hydrogen contact side. The gas flux control layer is positioned between the hydrogen contact side and the porous hydrophobic catalyst layer such that the flux of hydrogen may be controllably delivered to the porous hydrophobic catalyst layer. The membrane and method may be used to controllably synthesize hydrogen peroxide directly from hydrogen and oxygen without the use of organic solvents or complex equipment for ionic and electrical transport.

摘要:The present invention relates to a process of synthesis of silica-based adsorbents used in the CO2 capture process in oil fields with expressive volumes of associated CO2, aiming its subsequent use in processes of producing bioQAV and alcohol from the hydrogenation reaction. Adsorbents obtained based on silica and different metals have a high stability and activity in CO2 capture, at adsorption and desorption temperatures of 25° C., increasing the density of the silanol groups present in mesoporous silica, conducted by replacing Si in the crystal lattice with various metals. The insertion of elements in the structure is responsible for creating vacancies used to capture CO2, being characteristic of higher enthalpies involved in the process. Additionally, the exchange of silicon for metals is conducted during the hydrolysis process of the silica precursor, not requiring another step, in addition to being able to be conducted with low-cost precursors, such as chlorides, nitrates and isopropoxides, and an aqueous medium.

摘要:Procedures and methods for synthesizing biodegradable polymer coated nanoceria result in stable nanoparticle preparations in aqueous systems and physiological relevant colloidal solutions, such as phosphate buffer saline. The coated nanoceria preparations increase the nanoparticle concentration in aqueous or colloidal solutions as most needed for antioxidant, free-radical scavenger, and autocatalytic biomedical applications, including, biological, pharmacological and potential clinical use. To meet this need, a facile synthetic procedure for preparation of a biodegradable polymer-coated nanoceria is disclosed; the preferred biodegradable polymer is dextran. The synthesis method occurs under ambient conditions in an aqueous phase without the use of surfactants and results in a monodispersed preparation that is dextran-coated as determined by dynamic light scattering (DLS). Preliminary characterization of polymer coated nanoceria by XPS, TEM, XRD, and the like shows that these nanoparticles have the necessary physical properties for the desired biological potency, such as Ce +4 /Ce +3 mixed valence state.
