The invention relates to a device and process for converting organic waste to biogas with high methane content and improved organic conversion efficiency. Disclosed process consists of two stages and in the first stage, shredded organic waste is digested in primary digester in which biodegradable organic fractions present in waste gets converted to volatile fatty acids and alcohols dissolved in aqueous solution by hydrolytic and acidogenic microorganisms. Primary digester effluent pH, is adjusted to about 6.8-7.5 by addition of controlled alkali solution. Neutralized waste slurry is separated into liquid solution called as leachate and digested solid sludge. In the second stage, liquid leachate comprising volatile fatty acids are converted to biogas with methane content in the range 80-86% by methanogenic microbial culture in main digester under anaerobic conditions. This invention further describes optimized primary and main digester configurations with operating conditions to improve organic conversion efficiency in both the digesters.

The present invention relates to a synthesis of novel Zn(II)-based Metal Organic Frameworks having mixed organic ligands of 1,3,5-benzene tricarboxylic acid (BTC) and 2-methylimidazole (mIm) through a simple and economic solvothermal method. The synthesized MOFs has cuboids morphology having high surface area (1248 m2/g) capable of hydrogen adsorption at &#x2212;10&#xb0; C. to 25&#xb0; C. temperature and 100 bar pressure. The hydrogen adsorption capabilities of the novel MOFs are in the range of 23-0.2 weight percent.

The present invention relates to an apparatus and method for bio-assisted treatment of spent caustic obtained from hydrocarbon and gas processing installations. The present invention also relates to method for recovery of caustic and recovery of sulfur from spent caustic. According to present invention, the sulfide removal is about 96% and the sulphur formation and deposition on the electrode lies in range of 72&#xb1;8%.

The present invention relates to a novel polypouch for packaging of mineral oils. Said polypouch is made up of multilayered polymeric sheet or film of different inventive thicknesses by co-extruded unique combination of low density polyethylene, nylon and adhesive resin resulting in negligible permeation loss of packed mineral oils e.g. kerosene oil.
