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...

The pyrolysis of TVSb has been investigated in a flow tube reactor using Dz and He carrier gases. For TVSb alone, the most likely pyrolysis reaction involves an Sbcentered reductive elimination pathway. A less likely possibility is pyrolysis via homolysis of the Sb-C bonds, yielding vinyl radicals. Unfortunately, examination of the organic byproducts in both He and D, yields insufficient inform...

Abstract Sewage sludge (SS) is a residual/semi-solid material produced from industrial and municipal wastewater treatment processes. SS contains high content of lipids earth alkaline metals that can be used as catalysts for various chemical applications; however, its valorization has rarely been the focus research. This study demonstrates could promising raw biodiesel production biochar catalys...

Abstract In this study, physicochemical properties, co-pyrolysis kinetics and characteristics of lignite rapeseed cake is investigated. While has high calorific value, volatile matter content low moisture that suitable for the pyrolysis reactions. According to thermal behavior blends, addition into provides shift lower initial decomposition temperature blends compared lignite. a significant rol...
