Hydrothermal Carbonization (HTC) Technology for Tire Pyrolysis: A Comprehensive ReviewBy Sandeep Rai
Abstract: Hydrothermal Carbonization (HTC) is an innovative technology that is mimics of natural coal formation processes to convert wet biomass into valuable carbon-rich materials known as "biochar." This process involves subjecting organic matter, like agricultural waste, food residues, or sewage sludge, under high-pressure & moderate-temperature conditions (around 180-250°C & 2-4 MPa) in presence of water. HTC technology accelerates process of the dehydration & carbonization of biomass, thus producing a solid product …

Selective Recovery of Valuable Chemicals from Tire Pyrolysis Oil: A Sustainable ApproachBy Sandeep Rai
Abstract: The generation of waste/scrap/end-of-life tires (ELTs) poses severe environmental challenges globally. For the disposal of huge numbers of ELTs (generated every year) using conventional recycling methods, like as landfill or incineration, are not preferred due to their adverse environmental impacts. To overcome this problem, an alternative and promising technology is developed -the pyrolysis of waste tires. Pyrolysis is a thermochemical process that decomposes organic materials (Rubber Hydrocarbons) in the absence …

Hydrogenated Nitrile Butadiene Rubber (HNBR): A Comprehensive ReviewBy Sandeep Rai, Pradeep Uthale
Abstract: HNBR is produced by the hydrogenation of nitrile rubber (NBR) using either a homogeneous or heterogeneous technique. NBR is a copolymer of butadiene and acrylonitrile monomers. The hydrogenation process involves adding hydrogen to the nitrile butadiene copolymer, which results in improved resistance to heat, oxidation, and chemicals compared to NBR. This process alters the molecular structure of the rubber, providing it with superior properties compared to its unmodified counterpart, NBR. …

Comprehensive Review of EPDM (Ethylene Propylene Diene Monomer) RubberBy Sandeep Rai, Pradeep Uthale
Abstract: The terpolymer elastomer known as ethylene propylene diene monomer (EPDM) is made up of ethylene and propylene with trace amounts of a non-conjugated diene as a third monomer. This elastomer was created using the idea of limited olefinic functionality, which is brought about by diene monomer incorporating unsaturation into the polymer backbone. This random elastomeric copolymer, which has a fully saturated polymer backbone, has intriguing qualities such as good heat …
