The Promise of Biochar and Bio Oil

Biomass pyrolysis transforms organic material such as agricultural residues and wood chips into three main components: syngas, bio-oil and biochar (which contain about 60 per cent of the carbon contained in the biomass. Biomass pyrolysis process can be used to sequester the carbon and  remove circulating carbon dioxide from the atmosphere and stores it in virtually […]

Biomass Conversion Technologies

Biomass conversion technologies can be tailored for rural or urban environments, and utilized in domestic, commercial or industrial applications. A wide range of technologies are available for realizing the potential of biomass as an energy source, ranging from very simple systems for disposing of dry waste to more complex technologies capable of dealing with large amounts […]

Biorefinery – Source of Advanced Biofuels

A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and value-added chemicals from biomass. A biorefinery is analogous to a petroleum refinery, which produces multiple fuels and products from petroleum. By producing several products, a biorefinery takes advantage of the various components in biomass and their intermediates, therefore […]

Introduction to Biomass Pyrolysis

Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon […]

Gasification of Tannery Wastes

Wastes generated by the leather processing industries pose a major challenge to the environment. According to conservative estimates, about 600,000 tons per year of solid waste are generated worldwide by leather industry and approximately 40–50% of the hides are lost to shavings and trimmings. Everyday a huge quantity of solid waste, including trimmings of finished […]

Exploring Gasification of Solid Wastes

Gasification of solid wastes involve the reaction of carbonaceous feedstock with an oxygen-containing reagent, usually oxygen, air, steam or carbon dioxide, generally at temperatures in excess of 800°C. It involves the partial oxidation of a substance which implies that oxygen is added but the amounts are not sufficient to allow the fuel to be completely oxidised […]

Introduction to Hydrothermal Carbonization

Most would agree that the production of biofuels is important, even necessary, for our future. There are significant differences in the production of various biofuels, especially concerning the production of biocoal, which will impact the acceptance and use of biofuel in the future. This article focuses on one technology for the production of biocoal which […]
