Lignocellulosic biomass conversion to biofuels such as ethanol and other value-addedbio-products including activated carbons has attracted much attention. The developmentof an efficient, cost-effective, and eco-friendly pretreatment process is a major challengein lignocellulosic biomass to biofuel conversion. Although several modern pretreatmenttechnologies have been introduced, few promising technologies have been reported. Microwaveirradiation or microwave-assisted methods (physical and chemical) for pretreatment(disintegration) of biomass have been gaining popularity over the last few years owing totheir high heating efficiency, lower energy requirements, and easy operation. Acid and alkalipretreatments assisted by microwave heating meanwhile have been widely used for differenttypes of lignocellulosic biomass conversion. Additional advantages of microwave-basedpretreatments include faster treatment time, selective processing, instantaneous control, andacceleration of the reaction rate. The present review provides insights into the current researchand advantages of using microwave-assisted pretreatment technologies for the conversionof lignocellulosic biomass to fermentable sugars in the process of cellulosic ethanolproduction.

Lignocellulosic biomass conversion to biofuels such as ethanol and other value-added
bio-products including activated carbons has attracted much attention. The development
of an efficient, cost-effective, and eco-friendly pretreatment process is a major challenge
in lignocellulosic biomass to biofuel conversion. Although several modern pretreatment
technologies have been introduced, few promising technologies have been reported. Microwave
irradiation or microwave-assisted methods (physical and chemical) for pretreatment
(disintegration) of biomass have been gaining popularity over the last few years owing to
their high heating efficiency, lower energy requirements, and easy operation. Acid and alkali
pretreatments assisted by microwave heating meanwhile have been widely used for different
types of lignocellulosic biomass conversion. Additional advantages of microwave-based
pretreatments include faster treatment time, selective processing, instantaneous control, and
acceleration of the reaction rate. The present review provides insights into the current research
and advantages of using microwave-assisted pretreatment technologies for the conversion
of lignocellulosic biomass to fermentable sugars in the process of cellulosic ethanol
production.
