Minimal viable sugar yield of biomass pretreatment

Pretreatment optimization methods for increased sugar yields from biomass pyrolysis

In the search for a renewable energy source that could replace petroleum and other nonrenewable energy sources, pyrolysis of biomass is a hopeful alternative and pretreatment could further improve its potential. There are several possible routes for pretreating lignocellulosic biomass, but many need further refining before becoming economical. The main obstacle for the conversion of biomass to ...

Cellulosic Biomass Pretreatment and Sugar Yields as a Function of Biomass Particle Size

Three lignocellulosic pretreatment techniques (ammonia fiber expansion, dilute acid and ionic liquid) are compared with respect to saccharification efficiency, particle size and biomass composition. In particular, the effects of switchgrass particle size (32-200) on each pretreatment regime are examined. Physical properties of untreated and pretreated samples are characterized using crystallini...

Logistics and pretreatment of forest biomass

In large regions of the world, biomass is a very important source of energy. The global bioenergy market based on forest biomass is growing rapidly. About 92 % of the bioenergy in Sweden comes from forests. Biomass from forests is not homogenous. The locations, transport distances, and transport methods, can differ very much and the industries that need biomass as input prefer raw materials wit...

Radiation Pretreatment of Biomass

Dilute acid pretreatment and enzymatic hydrolysis of sorghum biomass for sugar recovery--a statistical approach.

Sorghum is one of the commercially feasible lignocellulosic biomass and has a great potential of being sustainable feedstock for renewable energy. As with any lignocellulosic biomass, sorghum also requires pretreatment which increases its susceptibility to hydrolysis by enzymes for generating sugars which can be further fermented to alcohol. In the present study, sorghum biomass was evaluated f...
