    摘要： The invention relates to a process carried out continuously in one or more reactors connected in series for the preparation of sodium titanate nanotubes and their derivatives obtained by ion exchange and/or thermal treatment, by reacting titanium oxides with sodium hydroxide under suitable hydrothermal conditions to obtain or control the morphology of nanostructural titanates. The reaction mixture is introduced continuously into the reactor at a feed rate that is the same as the rate of discharge of the product. When more than one reactor is used, the material leaving the first reactor is used to feed the next reactor, and a differential of temperature is applied between the reactors in such a way as to obtain in the average, a temperature of between 60° C. and 180° C.

    摘要： A process for preparing molecular sieves of type Y faujasite structure is described, as well as pre-shaped bodies of faujasite structure type Y molecular sieves. The process comprises preparing a precursor gel from a source of silica-alumina or a source of alumina and a source of silica with a template agent at a SiO2/Al2O3 greater than 7 and suitable for forming a type Y zeolite, drying the precursor gel and contacting the dried precursor gel with steam, optionally followed by caustic washing, without the formation of crystalline phases other than type Y zeolite being observed. Advantageously, the pre-shaped bodies prepared with the precursor gel of Y zeolite, when subjected to the process of the invention, will have their outer surface covered by type Y zeolite crystals. The molecular sieves so obtained may be employed as catalysts or adsorbents in various processes of the chemical or oil industry.

    摘要： The invention relates to a continuous process for the preparation of sodium titanate nanotubes and their derivatives obtained by ion exchange and/or thermal treatment, by reacting titanium oxides with sodium hydroxide under suitable hydrothermal conditions to obtain or control the morphology of nanostructural titanates.The method is carried out continuously in one or more reactors connected in series, where the reaction mixture is introduced continuously into the reactor at a feed rate that is the same as the rate of discharge of the product. When more than one reactor is used, the material leaving the first reactor is used to feed the next reactor, and preferably a temperature differential is applied between the reactors in such a way as to obtain a mean temperature of between 60 and 180° C., and the overall reaction time is short, being about 90 minutes or less.The nanostructures obtained can be later subjected to ion exchange and/or thermal treatment in an inert, oxidizing or reducing atmosphere in order to prepare adsorbents, catalysts, photocatalysts, electrocatalysts, or else electrodes for photovoltaic cells, lithium batteries, gas sensors and systems for the separation and storage of hydrogen.
