Effects of pyrolysis pressure and atmosphere on gasification reactivity of Shenfu char

open access: yes, 2005
The effects of pyrolysis pressure and atmosphere on the CO2-gasification reactivity of Shenfu char were investigated by using a pressurized-TGA. It is found that tar redeposition and repolymerization which occur during pressurized-pyrolysis under N2, i.e.

Selective Non‐Catalytic Reduction of NOx in the Exhaust Gas of Small Wood Gasification Boilers

open access: yesChemie Ingenieur Technik, EarlyView.
Kinetic studies of the SNCR reaction were conducted to investigate NOx reduction in the exhaust gas of small‐scale wood gasification boilers. Both the experimental results and the derived global kinetic model indicate that SNCR can achieve a significant reduction in NOx emissions under typical operating conditions. ABSTRACT The gas‐phase reaction of NO

Detailed gasification process of woody biomass-derived char with H2O and CO2 gasifying agents

open access: yesJournal of Thermal Science and Technology, 2020
To effectively utilize renewable biomass resources, gasification technology is being actively developed. Many studies have been performed regarding the gasification of biomass-derived char (i.e., biochar), where the gasification rate varies greatly with ...

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

Chemical Commodities via Pyrolysis of Biomass: Phase Equilibria Calculations to Develop Valorization Strategies

open access: yesChemie Ingenieur Technik, EarlyView.
This study exploits phase equilibria calculations to describe fundamental behavior of fast pyrolysis bio‐oil during recovery (condensation) and downstream fractionation (extraction). This information is combined with an overview of potential value chains to produce chemicals via biomass fast pyrolysis to assess strategies and synergies.

Pyrolysis of Rapeseed Oil Press Cake and Steam Gasification of Solid Residues

open access: yesEnergies, 2020
A deoiled rapeseed press cake (RPC) was pyrolyzed by heating at a slow heating rate to 1000 °C in a fixed bed reactor, and the produced char was then gasified to obtain data for the kinetic modeling of the process.

3‐Reactor Chemical Looping System for Point Source CO2 Capture and Subsequent Conversion for Liquid Fuel Production

open access: yesEcoEnergy, EarlyView.
This study presents a novel 3‐reactor chemical looping system for CO2 capture and subsequent utilization with biomass and natural gas for producing liquid fuels. Using Ca2Fe2O5\Fe2O3 oxygen carriers, it achieves 60% CO2 capture efficiency, ∼80% syngas purity, and autothermal operation, offering a scalable, carbon‐negative route to sustainable fuels ...

Effect of metal content on CO2 gasification behavior of K- and Fe-loaded bio-chars

open access: yesJournal of Thermal Science and Technology, 2014
The effects of Fe and K contents of Fe- and K-loaded chars containing 0-23% Fe and 0-20% K, respectively, with negligible amounts of poisoning elements, on the CO2 gasification behavior (C + CO2 → 2CO) were investigated in the temperature range of 750 ...
