Speciation of Sulfur in Biochar Produced from Pyrolysis and Gasification of Oak and Corn Stover
The effects of feedstock type and biomass conversion conditions on the speciation of sulfur in biochars are not well-known. In this study, the sulfur content and speciation in biochars generated from pyrolysis and gasification of oak and corn stover were determined. We found the primary determinant of the total sulfur content of biomass to be the feedstock from which the biochar is generated, w...
متن کاملEstimating Profitability of Two Biochar Production Scenarios: Slow Pyrolysis vs. Fast Pyrolysis
We estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt-%) but the disadvantage of producing a relatively low-value energy product (pyrolysis gas of modest heating value). The second scenario employs fast pyrolysis to...
متن کاملProduction and characterization of Biochar from Various Biomass materials By slow Pyrolysis
Biochar is the carbonaceous solid product of biomass pyrolysis which can be used as chemical feedstock for various purposes such as energy production, and adsorption of pollutants. In particular, application of biochar to the soil is gaining greater interests, which can reduce fertilizer consumption, increase crop yields, and sequestrate carbon. This study compares the characteristics of biocha...
متن کاملIBI White Paper: Pyrolysis and Gasification of Biosolids to Produce Biochar
Introduction The need to dispose of human-generated waste streams is growing in line with the expansion of urban population centers. This is particularly true for the byproducts of wastewater treatment. According to the US EPA, there are over 7 million dry tons of biosolids (stabilized sewage sludge) produced per year in the US. In 2004, 49% of biosolids were beneficially used—primarily for agr...
متن کاملBiochar for soil remediation and land reclamation
Land reclamation generally relates to the improvement of soils degraded by human activities, for example construction and certain forms of agriculture. Soil remediation refers to the process of removing, neutralizing or reducing the toxicity of certain compounds, often left by human activities such as mining and industry. Each degraded and/or contaminated site is potentially unique in its chara...
