Special Issue Information

Dear Colleagues,

Owing to the increased concern for climate change and oil shortage, carbon-neutral society has become an important research topic. Although various kinds of strong strategies are being suggested to realize a carbon-neutral society, the additional use of carbon capture and utilization (CCU) and biomass is being suggested as an essential process to achieve carbon-neutral targets. Among many technologies, catalytic pyrolysis of lignocellulosic biomass occupies important research because it can increase the value of final products as fuel or chemical feedstock. Many kinds of catalytic research using metals, zeolites, base catalysts, natural inorganics, etc., are being introduced in recent years. However, several limitations on the product quality and operation cost make us consider additional research to increase product selectivity and catalyst life. This Special Issue is dedicated to topics such as the catalytic pyrolysis of lignocellulosic biomass and/or catalytic upgrading of biomass pyrolysis products via various technologies, catalytic pyrolysis, ex situ upgrading of pyrolysis products, co-feeding of hydrogen efficient feedstock, hydrodeoxygenation, hydrogenation, etc.

It is our pleasure to invite you to submit a manuscript to this Special Issue. Reviews, communications, and full research papers related to catalyst use in the value addition of biomass fuel are especially welcome.

Peanut shells, a major economic and oil crop in China, boast an abundant availability and remarkably high lignin content compared to other agricultural residues. Previous work indicated that the modified hierarchical zeolite (Zn-ZSM-5/MCM41) was effective in promoting the conversion of intermediate macromolecules during the lignin pyrolysis reaction and enhancing the yield and selectivity of liquid products. Thereby, this study aims to improve the quality of liquid products in the ex situ catalytic microwave co-pyrolysis of peanut shells and LDPE by utilizing Zn-ZSM-5/MCM41. Employing a compound center experimental design, we optimized reaction conditions through response surface analysis. The impact of microwave pyrolysis temperature and the catalyst-to-feedstock ratio on yield distribution and liquid product selectivity was explored. Results indicated a marginal increase in liquid product yield with rising pyrolysis temperatures. Moreover, an initial increase followed by a subsequent decrease in liquid product yield was observed with an increase in the catalyst-to-feedstock ratio. Optimal conditions of 450 °C and a catalyst-to-peanut hull ratio of 2.34% yielded the highest bio-oil yield at 34.25%. GC/MS analysis of the bio-oil revealed a peak in hydrocarbon content at 68.36% under conditions of 450 °C and a catalyst-to-feedstock ratio of 13.66%. Additionally, the quadratic model effectively predicted bio-oil yield and the selectivity for major chemical components. This study underscores the potential of Zn-ZSM-5/MCM41 in optimizing liquid product quality during catalytic co-pyrolysis, offering insights into bio-oil production and its chemical composition.
