Latest Patents

One of his latest patents is titled "Continuous process for the preparation of sodium titanate nanotubes." This invention describes a continuous process carried out in one or more reactors connected in series for the preparation of sodium titanate nanotubes and their derivatives. The process involves reacting titanium oxides with sodium hydroxide under suitable hydrothermal conditions to control the morphology of nanostructural titanates. The reaction mixture is introduced continuously into the reactor, maintaining a consistent feed rate that matches the discharge rate of the product. When multiple reactors are utilized, the output from the first reactor feeds into the next, with a temperature differential applied to achieve an average temperature between 60°C and 180°C.

Another significant patent is the "Process for the production of biodiesel." This invention relates to the production of alkyl esters of carboxylic acids for use as biodiesel. It starts with the transesterification of triglycerides from vegetable or animal oils and fats, which can be used individually or in mixtures. The process employs heterogeneous catalysis using protonated lamellar titanate catalysts in nanostructured forms, including nanotubes, nanofibers, or nanosheets.
