Tailor-Made Green Diesel Blends Design using a Decomposition-Based Computer-Aided Approach

Model-Based Formulation of Biofuel Blends by Simultaneous Product and Pathway Design

“…A comprehensive methodology for computer-aided mixture design and formulation of blended products was been proposed by Gani and co-workers. − In their framework, a mixture design problem is formulated as a mixed-integer nonlinear program which is solved by means of a decomposition-based approach, i.e., the solution to the original problem is sought by considering a series of solvable subproblems and therefore by performing a sequential reduction of the number of blend candidates. This approach has been applied to a variety of case studies including the formulation of gasoline- and diesel-like fuels where the design objective has been to find optimal blend components for a so-called main ingredient, i.e., a fossil gasoline/diesel pseudocompound that must constitute the main part of all mixtures under consideration. − In the aforementioned works, fixed cost factors ($/L) assigned to the individual blend components have been the only process-related criteria explicitly included in the optimization problem. Recently, Ng and co-workers have developed a systematic methodology for mixture design in the context of integrated biorefineries that includes the identification of optimal conversion pathways via superstructure optimization once an optimal mixture has been determined based on CAMD techniques.…”

Identification of Promising Alternative Mono-Alcohol Fuel Blend Components for Spark Ignition Engines

“…Design methodologies can avoid expensive and time-consuming trial-and-error experimental campaigns. Similar approaches have been successfully used in several fuel development projects [4,[53][54][55][56][57][58][59][60], typically to design tailor-made molecules for fuel application. That is, molecular building blocks were computationally joined and reassembled to generate new molecules with good fuel blendstock potential.…”
