Bio-Char II: Production, Characterization and Applications

When assessing the usefulness of pyrolysis chars as porous materials for the application as adsorbents, catalysts or catalyst supports, one of the most important parameters of the assessment, besides the specific surface area, is their pore size distribution [1, 2]. The aforementioned processes are highly pore size selective, hence inappropriate pores sizes of the applied material can lead to the material’s uselessness for a given application. In terms of the application of pyrolysis char as a soil amendment (i.e., biochar), pore size also plays a major role. For example, in case of a too large share of micropores, even though …

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

Plant diseases are a threat to the health and functionality of both natural and man-made ecosystems. Diverse methods and strategies are being employed to prevent, ameliorate or control plant diseases. Unsustainable practices such as use and misuse of synthetic fungicides have caused severe harm to human health, wildlife and the environment (1). Fungal cause the most destructive plant diseases and impose major losses to both natural and production systems, and one of it is the fungi. Botanical fungicides are particularly sought after because they are abundant, selective, readily degraded, and are not toxic to mammals (2).

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 …

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

The integration of new CO2 capture and storage technologies into energy generation processes has led to the development and study of the oxy-fuel combustion, in which the nitrogen in the air is replaced by recirculated CO2 that facilitates its capture and storage to reduce polluting emissions. Currently, the integration of oxy-fuel technologies with the use of new fuels such as bio-oil obtained from the pyrolysis of biomass is a topic of interest. In this case, the CO2 content surrounding the bio-oil droplets modifies the pyrolysis mechanism due to barriers in the diffusion of light volatiles at low temperatures (less than …

Which Policy For Biochar Deployment In Southern Eu? An Integrated Approach Is Possible, David Chiaramonti

Biochar: Production, Characterization and Applications

The scope of the present paper is to address possible policy schemes that could potentially enable widespread diffusion of biochar in the EU Mediterranean area. In fact, despite the rapid development of biochar technologies and processes, the actual exploitation is mostly dependent on the actual support scheme that is in place. However, one single support instrument will unlikely be sufficient to cover the costs connected to biochar production and use: moreover, developing totally new policy instruments is a very long and time consuming process. The approach of the present work is to investigate the possibility of combining different EU policies …

How To Produce A Potential High Value Bio-Char From The Worst Invasive Plant In Canada, Chiara Barbiero, Franco Berruti, Cedric Briens

Biochar: Production, Characterization and Applications

Phragmites Australis is a perennial plant, native to Eurasia, which is spreading worldwide, increasing fire hazards, and causing damage to wildlife and its surrounding habitat. Phragmites is classified as Canada’s worst invasive plant due to the difficulty of achieving its full eradication. Phragmites plants are fast growing and can spread quickly through seeds or rhizomes. They must be processed locally to destroy seeds and rhizomes. For these reasons, mobile pyrolysis was selected as a destruction method that provides valuable bio-char. The aim of this work is to study the effect of different pre-treatment and post-treatment strategies on bio-char characteristics, such …

Pyrolysis Of Cotton Stalks And Utilization Of Pyrolysis Char For Sustainable Soil Enhancement And Carbon Storage, Sebastian Schaffer, Tobias Pröll, Rafat Al Afif, Christoph Pfeifer

Biochar: Production, Characterization and Applications

Worldwide, a large amount of biomass accumulates in the form of ligno-cellulosic agricultural by-products that can neither be efficiently used as animal feed nor as feedstock for anaerobic digestion. A clean and energy-efficient utilization in combustion plants is counter-indicated by high contents of elements like Cl, K and Na that decrease the ash-melting-point and lead to fouling and corrosion. Although this biomass is, therefore, not suitable for conventional combustion plants, a pyrolysis process can be applied that works at lower temperatures of 500-600°C.
