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...

Hydrocarbon potential evaluation is a high priority in oil/gas exploration which significantly influenced by methods and subjective cognition. With the aim of quantitatively establishing hydrocarbon generation expulsion (HGE) model source rocks, data-driven approach proposed based on abundant readily available Rock-Eval/total organic carbon content (TOC)/vitrinite reflectance (VRo) datasets. Th...

The effect of corn stover lignin structure alteration caused by white-rot fungi pretreatment on the pyrolysis kinetics was studied by FTIR and TG/DTA. Results showed that biopretreatment had a remarkable effect on lignin pyrolysis. Biopretreatment can decrease the activation energy and increase the pre-exponential factor in the initial stage of pyrolysis, which makes it possible to start the li...

This study proposes a method to calculate the retained oil content ( W O ) in cores collected by sealed tool from organic-rich shale with thermal maturity around%Ro = 0.8 Ordos Basin, China. Approaches such as soaking at low temperature, multiple extractions, pyrolysis, and chromatographic analyses were conducted then relationships between total mineral compositions analyzed. The measured propo...

The paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. This experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orth...

The Sirt Basin important oil producing area in Libya is one of the richest regions terms hydrocarbon resources. Exploration studies this have shown that oils are mixtures several charges and may be from different source rocks particularly upper Cretaceous sediments study based on organic geochemistry petrographic analysis carried out 179 cutting samples collected four wells. From Cenomanian to ...

Analytical pyrolysis is a technique currently used for investigating structural features of complex macromolecular materials. However, pitfalls appear to be widespread in pyrolysis studies of humic substances, and serious limitations can be experienced during the analytical procedure due to thermal reactions and configuration of the pyrolysis units and chromatographic systems. Pyrolysis present...

This thesis consists of uncertainty and techno-economic studies of two different biofuels production pathways (catalytic pyrolysis and gasification). The objective of this paper is to obtain a side-by-side techno-economic comparison of in situ and ex situ catalytic pyrolysis, and gasification state-of-technology and target scenarios that addresses both sensitivity and uncertainty analysis in th...
