Biogenic waste

We may differentiate between direct conversion of biomass into bioenergy (electricity and heat, solid fuels from biogenic wastes and residues, biogas, etc.) and biofuels. Catalysis has a minor role in the first case but is a critical element in the production of biofuels. However, notably, there are also potentially interesting developments related to bioenergy.

Apart from the use of biogenic waste, the feedstock for biobased products is provided from agricultural production of crops or from harvesting of silvicultural products. In both cases, land is the primary resource. However, it has become obvious that land is not simply used continuously in more or less the same way, but that major changes in land use may be induced by a rising demand of biobased products, for example, the conversion of tropical forests into plantations for sugarcane, which alter the quality of land and the respective ecosystems. 

Biogenic wastes and residues from biotope and landscape conservation, agriculture and forestry contain characteristic amounts of woody biomass dependent on their provenance and composition, (see Table 1 for a... 

Methane is a major component of natural gas. An additional source of methane is the fermentation of biogenic waste, forming the so-called biogas that contains methane as a major component Synthetic methane can be obtained by hydrogenation of CO (AH= 207kJ mol ) over Ni/Al203 catalysts at 300-600 °C and...
