Evaluation of catalytic pyrolysis of cassava rhizome by principal component analysis

A survey of catalysts for aromatics from fast pyrolysis of biomass

“…The use of highly porous MCM-41 silica support to prepare mesoporous sulfated zirconia (MSZ) increased the surface area to 217 m 2 /g. But this number was significantly less than the surface area reported by Sigma-Aldrich (approximately 1000 m 2 /g) for unmodified MCM-41 [15]. Deposition of zirconium oxide on MCM-41 may have blocked the pore openings reducing their volume.…”

“…Transition metal modified MCM-41 has been shown to increase selectivity for hydrocarbons and reduce oxygenates (organic molecules with oxygen functional groups such as acetic acid, glycolaldehyde, etc.) from biomass pyrolysis vapors [11,15,16]. Therefore, the preparation of sulfated zirconia supported on mesoporous MCM-41 is demonstrated and its activity in upgrading pyrolysis vapor is investigated.…”

Catalytic Vapor Cracking for Improvement of Bio-Oil Quality

“…Pattiya et al [73] undertook catalytic pyrolysis, using Py-GC/MS, to investigate the effects of various catalysts, such as zeolites and zeolite-related materials, metal oxides, proprietary commercial catalysts and natural catalysts, on the pyrolytic products. The results indicated that ZSM-5, Criterion-534, as a proprietary catalyst, and Al-MSU-F catalyst reduced all of the oxygenated lignin-derived compounds and concomitantly enhanced the formation of aromatics and phenols.…”

Applications and Preparation Methods of Copper Chromite Catalysts: A Review

“…The severity of these catalytic reactions often influences the liquid product distribution and depends largely on types of catalyst and other processing parameters. Pattiya et al [198] used copper chromite catalyst for cassava rhizome as the biomass feedstock for upgrading bio-oil. They observed that the copper chromite was selective to the reduction of most oxygenated lignin derivatives.…”
