Steam Gasification Of Biomass Surrogates: Catalyst Development And Kinetic Modelling, A S M Jahirul Islam Mazumder

Electronic Thesis and Dissertation Repository

This study reports a new fluidizable La₂O₃ promoted Ni/γ-Al₂O₃ catalyst. Prepared catalysts are characterized using BET specific surface area, XRD, TPR, TPO, H₂-pulse chemisorptions, Pyridine FTIR, NH₃-TPD and CO₂-TPD. Catalytic steam gasification of biomass surrogates (glucose and 2-methoxy-4-methylphenol) are conducted in a CREC Riser Simulator under the expected conditions of a twin circulating fludized bed gasifier.

Catalyst structure-property and structure-reactivity relationships are established using characterization and gasification results. Gasification performance of a catalyst is found to be well-correlated as a function of its Ni dispersion and basicity/acidity ratio. …
