Steam gasification of acid-hydrolysis biomass CAHR for clean syngas production
چکیده انگلیسی


• Steam gasification of CAHR as matter and energy recovery was investigated.
• CAHR steam gasification in terms of temperature and S/B ratio was examined.
• Gasification yielded more hydrogen and energy than that obtained from pyrolysis.
• The maximum value of energy ratio, 0.855, was found.
• Steam gasification is a promising method to produce hydrogen from AHC.

Main characteristics of gaseous product from steam gasification of acid-hydrolysis biomass CAHR have been investigated experimentally. The comparison in terms of evolution of syngas flow rate, syngas quality and apparent thermal efficiency was made between steam gasification and pyrolysis in the lab-scale apparatus. The aim of this study was to determine the effects of temperature and steam to CAHR ratio on gas quality, syngas yield and energy conversion. The results showed that syngas and energy yield were better with gasification compared to pyrolysis under identical thermal conditions. Both high gasification temperature and introduction of proper steam led to higher gas quality, higher syngas yield and higher energy conversion efficiency. However, excessive steam reduced hydrogen yield and energy conversion efficiency. The optimal value of S/B was found to be 3.3. The maximum value of energy ratio was 0.855 at 800 °C with the optimal S/B value.
