Lignocellulose HydrolysisLignocellulosic biomass, primarily comprised of cellulose, hemicellulose, and lignin, is an abundant and renewable resource that holds great promise as a source of biofuels and renewable biobased chemicals and biomaterials. Lignocellulosic biomass can be processed in a number of ways, one is through the hydrolysis of the structural polysaccharides (cellulose and hemicellulose) into their constituent sugars, a reaction commonly facilitated by acid or enzymes, followed by the fermentation of these sugars by yeast or other microorganisms.
Acid HydrolysisHydrolysis of lignocellulose can be catalysed with acids. These can be used in either dilute or concentrated forms, with each approach having its own advantages and disadvantages.
Concentrated-Acid ProcessConcentrated acid hydrolysis, unlike its dilute counterpart, involves the use of acids in high concentrations to disrupt and hydrolyse the complex polysaccharides (cellulose and hemicellulose) present in lignocellulosic biomass into simpler, fermentable, sugars. The most commonly used acid in this process is sulphuric acid due to its strong acidity, but other types of acids (e.g. hydrochloric acid) can be used.
Effect of Process ConditionsThe efficiency and output of concentrated acid hydrolysis are heavily influenced by several key process variables, detailed below:
