Iron-based industries are one of the main contributors to greenhouse gas (GHG) emissions. Partial substitution fossil carbon with renewable biocarbon (biomass) into blast furnace (BF) process can be a sustainable approach mitigating GHG emissions from ironmaking process. However, barriers using biomass for this purpose inherent high alkaline and phosphorous contents in ash, resulting fouling, s...

The utilization of bio-based side streams in metallurgical coke making promotes two major factors the mitigation climate impact steel industry. Circular economy as waste material from biorefinery industry is utilized a raw industry, and production fossil-based CO2 emissions. In this work, lignin hydrolysis process was used briquetted form part blend making. For experiments analyses, briquettes ...

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...

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...

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...
