Intellectual Property India Publishes Patent Application for 'A Plasma Gasification Process For Production Of Hydrogen Rich Syngas From Paper Mill Sludge' Filed by Indian Institute Of Technology (Indian School Of Mines)

MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202631026517 A) filed by Indian Institute Of Technology (Indian School Of Mines), Dhanbad, Jharkhand, on March 6, for 'a plasma gasification process for production of hydrogen rich syngas from paper mill sludge.'

Inventor(s) include Dr. Snehlata Kumari; and Dr. Ejaz Ahmad.

The application for the patent was published on March 13, under issue no. 11/2026.

According to the abstract released by the Intellectual Property India: "A plasma gasification process for production of hydrogen rich syngas from paper mill sludge. The plasma gasifier system (100) comprising of a high temperature zone (101), a low temperature zone (102), slag collection zone (103), a feed inlet (110), plasma torch (120), a nitrogen inlet (121), a syngas outlet (130) and a slag removal unit (140). The plasma gasification process for production of hydrogen rich syngas from paper mill sludge, comprising the following steps: (1) the paper mill sludge being semi-dried to reduce the moisture content slightly before being fed to the plasma gasifier through a feed inlet (110) so that the sludge forms a gasification bed in the heating zone of the gasifier; (ii) a plasma torch (120) is operated using nitrogen as the plasma working gas to generate a high-temperature nitrogen plasma in the gasifier to initiate plasma gasification process; (iii) a high temperature zone (101) is established in its vicinity and a low temperature zone (102) in the upper section; (iv) during plasma-assisted gasification, the moisture is converted to steam, the organic fraction is converted to a gaseous product comprising hydrogen-rich syngas which is collected through syngas outlet (130)."
