... benefits for the environment. However, there are some obstacles in the way of manufacturing the cellulosic biofuels at a large scale and doing so cost effectively. One obstacle is the low sugar yield of biomass in enzymatic hydrolysis, leading to low efficiency in biomass-biofuel conversion and thus high...

... sugar yield. The literature contains many studies investigating the relationship between particle size and sugar yield. Many studies focused only on the sugar yield in enzymatic hydrolysis, and failed to take into account the biomass weight loss during pretreatment. This weight loss results in a loss...

.... KEYWORDS Cellulosic biomass, Density, Durability, Energy consumption, Ethanol, Pellet, Sugar yield, Ultrasonic vibration INTRODUCTION Petroleum-based liquid transportation fuels (including gasoline, diesel, and jet fuels) account for 70% of U.S. oil consumption [1]. The increasing demand of liquid...

... biofuels from cellulosic biomass requires reduction of the material size using mechanical comminution methods. This paper reviews these mechanical comminution methods. It presents their effects on biomass particle size, cellulose crystallinity, and sugar yield. It also discusses the characteristics of each...
