Enhanced production of hydrocarbons from the catalytic pyrolysis of maize straw over hierarchical ZSM-11 zeolites

Liu Wu et al.

Summary: The importance of ZSM-11 zeolite as a catalyst for producing hydrocarbon-rich bio-oil through catalytic fast pyrolysis (CFP) of biomass has been revealed in this study. By synthesizing and testing ZSM-11 with different morphologies, acidities, and secondary mesopores, it was found that nanosized ZSM-11 with optimal acidity and introduced mesopores showed improved bio-oil yield and hydrocarbon selectivity. NS-ZSM-11 (20)-0.3 exhibited satisfactory bio-oil yield and hydrocarbon selectivity, along with excellent reusability in regeneration-pyrolysis cycles.

Liu Wu et al.

Summary: Catalytic fast pyrolysis (CFP) is an efficient method for converting biomass waste into biofuels, and the choice of catalyst is crucial for its success. In this study, the researchers tested ZSM-11 zeolite with straight channels as a potential catalyst for biomass CFP. The ZSM-11(40) catalyst showed excellent deoxygenation ability and suppressed coke and polyaromatic formation. Furthermore, the catalyst exhibited good reusability after three cycles.

Fischer-tropsch synthesis in monolith catalysts coated with hierarchical ZSM-5

Chunxiang Zhu et al.

Summary: Fischer-Tropsch synthesis is explored as a one-step process for converting synthesis gas to hydrocarbons, with novel catalysts for in-situ upgrading of products synthesized and tested. The use of hierarchical ZSM-5 co-catalysts relaxes mass transfer limitations, improving conversion and selectivity. Loss of catalyst activity due to pore plugging is observed, but in-situ regeneration enables stability in FTS performance.

Effect of Mesopores in ZSM-5 on the Catalytic Conversion of Acetic Acid, Furfural, and Guaiacol

Qingfeng Che et al.

Summary: Recent studies have shown that mesoporous ZSM-5 catalysts exhibit higher catalytic efficiency in converting biomass into renewable aromatic hydrocarbons compared to conventional microporous catalysts. The larger mesopores in the catalyst provide more channels for reactant transportation, leading to increased aromatics production, while the smaller mesopores facilitate multistage cracking and coke deposition. This research highlights the importance of mesoporous structure in improving the catalytic conversion efficiency of biomass and suggests future investigation into hierarchical mesopore structures.

Zeolites as effective desiccants to solve hygroscopicity issue of post-consumer mixed recycled polyolefins

Emilia Garofalo et al.

Summary: This study addresses the hygroscopicity issue of post-consumer mixed recycled poly-olefins (PCMP) and proposes a novel solution using zeolites as desiccant additives during PCMP extrusion. The results show that zeolites can effectively function as desiccants during PCMP processing, ensuring higher strength of the resultant systems compared to traditional drying methods. The use of a compatibilizing agent further improves mechanical performance, offering a tangible contribution to the sustainability of the packaging industry and EU plastic recycling targets.
