“…Oxidation regeneration by burning coke at high temperature in air was attempted to recover zeolite catalyst activity [60,73,89]. In order to avoid the irreversible loss of acidity, the catalysts' regeneration temperature should not exceed the catalyst calcination temperature.…”

“…In order to improve hydrothermal stability of the HZSM-5 catalyst, a high SiO 2 /Al 2 O 3 ratio (80) and nickel incorporation (1 wt%) were used to modify HZSM-5 zeolite (SiO 2 /Al 2 O 3 ratio of 30) during bio-oil catalytic cracking at 500 • C in a fluidized bed reactor [89]. The modified HZSM-5 catalysts regeneration were conducted by combusting coke with air at 550 • C for 2 h, the regenerated catalysts maintained similar activities for ten reaction-regeneration cycles.…”

Abstract:The massive consumption of fossil fuels and associated environmental issues are leading to an increased interest in alternative resources such as biofuels. The renewable biofuels can be upgraded from bio-oils that are derived from biomass pyrolysis. Catalytic cracking and hydrodeoxygenation (HDO) are two of the most promising bio-oil upgrading processes for biofuel production. Heterogeneous catalysts are essential for upgrading bio-oil into hydrocarbon biofuel. Although advances have been achieved, the deactivation and regeneration of catalysts still remains a challenge. This review focuses on the current progress and challenges of heterogeneous catalyst application, deactivation, and regeneration. The technologies of catalysts deactivation, reduction, and regeneration for improving catalyst activity and stability are discussed. Some suggestions for future research including catalyst mechanism, catalyst development, process integration, and biomass modification for the production of hydrocarbon biofuels are provided.

“…Among them, ZSM-5 has seen considerable use in industry as solid acid catalysts particularly in the fields of oil refining and petrochemistry. Because of its outstanding hydrothermal stability and high selectivity to light olefins, ZSM-5 zeolite has been widely used as the active component in catalytic cracking catalysts [4,5], aromatic alkylations [6][7][8][9], upgrading of bio-oils from pyrolysis of lignocellulosic biomass to produce fuels and chemicals [10][11][12][13][14][15] and conversion of triacylglycerides to light alkanes and aromatics [16,17]. Furthermore, one of the additives used in commercial FCC operation is based on the zeolite ZSM-5 [18].…”

“…Several researchers have used zeolite catalysts to convert carbohydrate and biomass feeds into aromatics [1][2][3][4][5][6]. Acidic catalysts enable cracking reactions that remove Al-MSU-S catalysts have acidity as well as hydrothermal stability, necessary for highly corrosive applications such as fast pyrolysis [11].…”
