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 …

Effect Of Pyrolysis Conditions On Sewage Sludge Derived Biochars For High Value Composites Applications, Paola Giudicianni, Maurizio Troiano, Roberto Solimene, Raffaele Ragucci, Mauro Giorcelli, Alberto Tagliaferro, Mattia Bartoli

Bio-Char II: Production, Characterization and Applications

The economy of the whole wastewater treatment system is significantly burdened by the increasing amounts of sewage sludge due to the progressive implementation of the Urban Waste Water Treatment Directive 91/271/EEC and by the complexity of the treatments required for guaranteeing a safe handling and a proper end-of-life of the sludge. For this reason, thermal treatments of sewage sludge have been studied in the past for their efficient valorization in terms of energy and/or matter recovery. Among them, pyrolysis represents a viable route aiming at the recycling of resources without production of harmful substances to the humans or the environment. …

Biochar Production Though Combined Solar Drying & Single Chamber Pyrolysis, Dirk Weichgrebe, Moni M Mondal, Rahul Ramesh Nair

Bio-Char II: Production, Characterization and Applications

In this study, the challenging management of fibrous organic wastes (FOW) and dewatered municipal sewage sludge (MSS) in urban areas of Asia’s newly industrialised countries is presented with high energy efficiency, negative CO₂ balance and biochar generation. This study investigates the feasibility and benefits of a combined treatment approach for both of the substrates, comprising solar drying (SD) and pyrolysis process (PYR). Based on material investigations, a calculation model is developed to project the material and energy flows of this process combination on the example of Chennai, India.

Influence Of Heating Rate On The Solid Yield Of Biomass Pyrolysis, Markus Lang, Kathrin Weber, Peter Quicker

Bio-Char II: Production, Characterization and Applications

The use of biochar has become increasingly popular over the last decade. The possible applications are vast and range from renewable carbon carrier in industrial and energetic applications to soil amendment and fodder additive. The various applications have different demands on the properties of biochar. These can be influenced by the choice of feedstock, reactor and production conditions. Regardless of production process and application however, achieving a high yield of the solid product is desirable from an economic point of view. The higher the treatment temperature, the more material is devolatilized and the lower is the amount of biochar that …

Influence Of Feedstock And Operational Conditions On Bio-Chars Derived From The Pyrolysis Of Selected Biomasses, David Chiaramonti, David Casini, Giovanni Ferraro, Emiliano Fratini, Giuditta Pecori, Andrea Maria Rizzo, Luca Rosi

Bio-Char II: Production, Characterization and Applications

The proprieties of bio-char, the solid product from biomass pyrolysis, depends on both the feedstock and process conditions during thermochemical conversion^[1]. As regards the interaction of the char with soil (i.e. as soil amendment), surface areas, size and shape of pores are among the most important factors to be considered.
