Biochar affected by composting with farmyard manure.
Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated ...
متن کاملSpeciation 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 کاملEmissions and Char Quality of Flame-Curtain "Kon Tiki" Kilns for Farmer-Scale Charcoal/Biochar Production
FLAME CURTAIN BIOCHAR KILNS Pyrolysis of organic waste or woody materials yields charcoal, a stable carbonaceous product that can be used for cooking or mixed into soil, in the latter case often termed "biochar". Traditional kiln technologies for charcoal production are slow and without treatment of the pyrolysis gases, resulting in emissions of gases (mainly methane and carbon monoxide) and ae...
متن کاملGasification reactor engineering approach to understanding the formation of biochar properties
The correlation between thermochemical provenance and biochar functionality is poorly understood. To this end, operational reactor temperatures (spanning the reduction zone), pressure and product gas composition measurements were obtained from a downdraft gasifier and compared against elemental composition, surface morphology and polyaromatic hydrocarbon content (PAH) of the char produced. Pine...
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...
