â¢Biomass and heavy oil deposits are prospective fuel sources for the future.â¢Upgrading with modified hydrophobic zeolites would be a viable option.â¢Incorporation of F, P, silanes and rare-metals is prioritized in recent times.â¢H-BEA, H-ZSM-5 (MFI), and H-Y (FAU) zeolites have so far been evaluated.â¢Further investigations are necessary to realize the full benefits.
The future applications of zeolite catalysts could target the valorization of abundant biomass resources and the widely distributed heavy oil deposits. However, a major challenge that can limit this possibility is the low stability of the zeolite systems under the hydrothermal conditions. The paper therefore reviewed classified literature on the different methods being considered for improving the stability properties of zeolite catalysts. Zeolite frameworks modification with fluoride ions, phosphorus, rare metals and silanes provides an opportunity for improving the stability during reactions like cracking, alkylation, isomerization, dehydration etc. All of these reactions are commonly encountered during biomass valorization in hydrothermal media and the heavy oil valorization via catalytic cracking and/or aquathermolysis. The paper thus tailored the progress made and identify the directions for further investigations.
