In silico solvent selection for optimum lignin depolymerisation process

2023

Abstract

The lignin polymer is the most abundant natural source of renewable aromatic molecules. Lignin depolymerization is a set of complex reactions for which kinetic modelling is challenging. The impact of the solvent on monomer yield was modelled based on limited experimental data, therefore enabling in silico testing of promising candidates from the GSK list of green solvents. Using ethanol as the solvent could decrease the CO2 emissions by 82% compared to the base case with tetrahydrofuran. The design was found to be most sensitive to coefficients linking solvent polarity and yield. By implementing a feedback loop between the lab-scale and process design, this methodology can guide experimental work with process-level considerations, therefore accelerating the development of biorefining processes.

Solvent

A solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. Specific uses for organic solvents are in dry cleaning (e.

Design

A design is a concept of either an object, a process, or a system that is specific and, in most cases, detailed. Design refers to something that is or has been intentionally created by a thinking agent, though it is sometimes used to refer to the nature of something. The verb to design expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan may also be considered to be a design (such as in some artwork and craftwork).

Product design

Product design as a verb is to create a new product to be sold by a business to its customers. A very broad coefficient and effective generation and development of ideas through a process that leads to new products. Thus, it is a major aspect of new product development. Product design process: the set of strategic and tactical activities, from idea generation to commercialization, used to create a product design. In a systematic approach, product designers conceptualize and evaluate ideas, turning them into tangible inventions and products.
