Preparation and Modification of Biochar Materials

The preparation ways of biochar are primarily divided into pyrolysis, hydrothermal carbonisation (HTC), and microwave carbonisation. Different preparation ways affect the physical and chemical properties of biochar, such as yield, ash, specific surface area, pore structure, type and variety of useful groups, and cation exchange capacity. Compared with the pyrolysis, HTC doesn’t need drying step …

Production of Hydrogen from Biomass

Biomass gasification is a well-established technological process that converts biomass into hydrogen and other products without burning through a regulated process including heat, steam, and oxygen. The net carbon emissions of this approach can be minimal since growing biomass absorbs carbon dioxide from the atmosphere; this is especially true if carbon capture, use, and storage …
