Tailor-made green diesel blends design using a decomposition-based computer-aided approach

Abstract

In this study, the tailor-made green diesel blend design problem is mathematically formulated and solved by a decomposition-based computer-aided approach. The green diesel design problem is solved in three main stages to identify the feasible green diesel blend candidates that meet the product property constraints (density, kinematic viscosity, cetane number, higher heating value and flash point) with the desired performance criteria. An optional additives identification step is introduced to enhance the blends. The shortlisted green diesel blends are evaluated on the basis of cost, cetane number and higher heating value. To ensure that the shortlisted candidates have acceptable functional reliability, their compatibility with the engine compartment, engine performance, and emission requirements should be addressed in future works.
