MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202621001434 A) filed by Dr. Vishwanath Karad Mit World Peace University, Pune, Maharashtra, on Jan. 6, for 'efficient system and cost-effective method for biodiesel production using agro-waste-based heterogeneous catalyst.'

Inventor(s) include Niraj S. Topare; Sujay H. Sawant; Dushyant S. Ojha; Akshit V. Parikh; Pranav P. Pandit; Brindesh D. Jodhani; Ketan R. Patil; Rucha P. Godase; Manisha R. Pardeshi; and Anish Khan.

The application for the patent was published on Feb. 27, under issue no. 09/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to an operationally efficient jacketed batch reactor agitation apparatus (100) for biodiesel production using agro-waste-based heterogeneous catalysts. The apparatus comprises a reactor shell (208) defining a reaction chamber, a cooling jacket (210) disposed around the reactor shell for temperature regulation, and a heating coil (206) arranged in thermal association with the reactor shell to supply controlled heat. A raw material inlet (202) enables introduction of reactants, while a product outlet (104) facilitates discharge of reaction products. A motor-driven agitation mechanism mounted at an upper portion of the apparatus ensures effective mixing during transesterification, and a condenser mounting (302) supports a condenser to minimize methanol loss. The reactor assembly is supported by a stand (304) providing mechanical stability. The apparatus is configured to perform transesterification of neem oil using activated carbon-based agro-waste heterogeneous catalysts, enabling controlled batch operation under regulated thermal conditions."
