In present study 7 carriers such as agar –agarose, wood fiber, wood chips, gelatin, wood powder, calcium alginate and butanol sodium alginate were used for immobilization of fungal amylase. Amylase immobilization was carried out by simple adsorption, adsorption followed by cross-linking, combined adsorption and gel entrapment methods. The suitability of the supports and techniques for the immob...

The aim of this work is to build CFD tools study heat transfer in packed beds during the thermochemical upgrading process woody biomass. For that purpose, a numerical workflow capable investigating phenomena inside bed was developed. First, generated using Discrete Element Method (DEM) code. Then, steady-state Direct Numerical Simulation (DNS) solver used acquire flow patterns pores bed. Finall...

Biomass is the oldest form of energy used by human beings, mainly in the form of wood. It is a renewable source of energy and has many advantages from an ecological point of view. The direct combustion of biomass generates concern among environmentalists, as it is incomplete and inconsistent and may produce organic particulate matter, carbon monoxide and other organic gases. Biomass gasificatio...

The State of Tennessee consists of 95 counties endowed with abundant forest resources that encompass more than 13.3 million acres. The forest products industries in Tennessee consist of two major industries: the primary and secondary wood processing industries. This study examined if there are differences among counties in the primary wood processing industries as related to employment, payroll...

The lack of raw materials to provide power plants with biofuel requires the search for new energy sources. In European North Russia, it is recommended grow plantings willow (Salix L.) in form trees or tree-like shrubs, while ensuring a short interval between fellings. studies show that artificial cultivation plantations on postagrogenic lands economically more expedient than exploitation natura...
