Adsorption of aromatics with diesel engine derived soot

The diesel engine combustion process produces carbonaceous deposits known as soot. Such carbonaceous deposits are accumulated at critical locations in a diesel engine, with detrimental effect on engine performance. The main objective of this project is to explore the role of polymers and additives, on the stability of carbon black, soot model, in organic solvents. Lubrizol uses a wide range of polyolefin derivatives, such as polar head groups grafted onto saturated polymers, as lubricants in diesel engine oil. A new generation of additive, known as a Dispersant Viscosity Modifier, that has dual functional properties in a single molecule, has been synthesised. The additive can be used for both dispersancy and viscosity modification. It is composed of a long hydrocarbon chain and a polar head group.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
