Abstract
The present disclosure relates to a process for producing anhydrosugar(s) from lignocellulosic biomass. In particular, the present disclosure relates to a process for producing anhydrosugar(s) from lignocellulosic biomass by pre-treating the lignocellulosic biomass by contacting it to either an acid or an acidic solution to obtain a pretreated lignocellulosic biomass and subjecting the pretreated lignocellulosic biomass to active pyrolysis followed by condensation to obtain the anhydrosugar(s) in high yield. Further, the present disclosure encompasses utilizing the food organic waste, date pits biomass for production of anhydrosugar(s), Levoglucosan in high yield.
Claims20
A process for producing one or more anhydrosugars from lignocellulosic biomass containing minerals including alkali and/or alkaline earth metal (AAEM) comprising:
- pre-treating the lignocellulosic biomass by contacting it to either an acid or an acidic solution to reduce the concentration of minerals including the alkali and/or alkaline earth metal (AAEM), followed by washing and drying to obtain a pretreated lignocellulosic biomass;
- and
- subjecting the pretreated lignocellulosic biomass to active pyrolysis followed by condensation,
- wherein the active pyrolysis is carried out in a reactor, wherein the reactor temperature is ramped up at a rate of about 10° C. per minute, and wherein said active pyrolysis is carried out at a temperature in a range of from about 300° C. to about 500° C.
