Logistics and pretreatment of forest biomass

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...

Predicting and Controlling Moisture Content to Optimise Forest Biomass Logistics

Nacrtak Wood fuel quality attributes have to be considered by logistics planners if fuel procurement from forests and energy production at the plant are considered simultaneously. The single most important quality attribute is the moisture content (MC) of chips or raw material delivered to energy plants. It affects heating value, storage properties, chipping and transport costs of the fuel. To ...

Radiation Pretreatment of Biomass

High-throughput Pretreatment and Hydrolysis Systems for Screening Biomass Species in Aqueous Pretreatment of Plant Biomass

The primary barrier to low-cost biological conversion of lignocellulosic biomass to renewable fuels and chemicals is plant recalcitrance, that is to say, resistance of cell walls to deconstruction by enzymes or microbes [1,2]. However, the discovery and use of biomass species with reduced recalcitrance, when combined with optimized pretreatment processes and enzyme mixtures, could potentially i...

Hydrothermal Pretreatment of Lignocellulosic Biomass and Kinetics

The study focus was an examination of the hydrothermal pretreatment method applied to the lignocellulosic substrate, represented by the prairie cord grass, and comparison between different conditions based on the yield of glucose after enzymatic hydrolysis. The treatment did not involve any chemicals usage. Enzymatic hydrolysis was performed in order to examine the amount of glucose which was r...

Microbial pretreatment of biomass: potential for reducing severity of thermochemical biomass pretreatment.

Typical pretreatment requires high-energy (steam and electricity) and corrosion-resistant, high-pressure reactors. A review of the literature suggests that fungal pretreatment could potentially lower the severity requirements of acid, temperature and time. These reductions in severity are also expected to result in less biomass degradation and consequently lower inhibitor concentrations compare...
