Abstract
Biomass is considered as the most sustainable and renewable resource for the synthesis of value added potential platform chemicals. Various techniques are utilized to extract or to pre-treat or to isolate various value added chemicals from biomass. Pre-treatment of the biomass is a very essential aspect to enhance the biomass processing yield which is attributed to reduced lignin content/delignification, cellulose crystallinity and hemi-cellulose hydration. In search of efficient extraction and processing for biomass treatment, supercritical fluid (SCF) has been considered as the green technique to obtain the value added chemicals with higher efficiency than conventional technique. The use of the supercritical carbon dioxide (SC–CO2) pre-treatment on biomass not only enhances glucose yield effectively but also delignify, hydrolyse hemi-cellulose component and allows extraction of various compounds from the biomass. However, very limited research articles are available for the use of SC-CO2 for biomass processing to obtain value-added chemicals. In view of this, the present review article focus on the recent advances of applications of SC-CO2 in (i) extraction of value added chemicals from biomass processing, (ii) biomass pre-treatment, (iii) factors affecting SC-CO2 processing efficiency, (iv) scale-up scenario (v) challenges and opportunities in this field.
