Anaerobic Digestion Of The Aqueous Pyrolysis Condensate, Franco Berruti, Cesar Miguel Moreira Valenzuela, Lars Rehmann, Connie Wen
Anaerobic Digestion Of The Aqueous Pyrolysis Condensate, Franco Berruti, Cesar Miguel Moreira Valenzuela, Lars Rehmann, Connie Wen
Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes
Fractional condensation of biomass pyrolysis vapors allows the segregation of different pyrolysis fractions and a separation of an aqueous pyrolysis condensate from an organic rich dry bio-oil fraction. Aqueous pyrolysis condensate is often referred at as “wood vinegar” or “pyroligneous acid” since it contains 70-80% water together with 10-20% acetic acid, and smaller quantities of acetone and methanol mixed with hundreds of other chemicals in small concentrations. Such aqueous pyrolysis condensate cannot be easily disposed of, and it may represent a valuable resource. For example, the significant percentage of acetic acid offers the opportunity to attempt its conversion into methane …

Biomethane Production From Distillery Wastewater, Zachary Christman
Biomethane Production From Distillery Wastewater, Zachary Christman
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Distillery wastewater treatment is a great ecological problem, for example, India produces 2.7 billion liters of alcohol that results in 40 billion liters of wastewater. However, this material can be seen as a resource since 11 million cubic meters of biogas at 60% methane could be produced in addition to cleaning the water. The distillery has two options of what to do with the biogas. The first is to use the biogas to fuel the distillery making the production plant more energy efficient and removing some of the need to buy natural gas. The other is to upgrade the biogas …
Improving The Distribution And Use Of Biogas By Conversion To Methanol, Zachary Christman
Improving The Distribution And Use Of Biogas By Conversion To Methanol, Zachary Christman
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
In this technology review, the process of turning an average biogas into methanol will be presented. The purpose is to find a better method of transporting the energy contained within biogas so that it may be used in industry as a value added product. The first step is removal of hydrogen sulfide, a corrosive chemical that can breakdown mechanical parts. The second step is carbon capture and conversion of the biogas into hydrogen. The final step is the hydrogenation of carbon dioxide into methanol using a copper catalyst and an alcohol co-catalyst.
