The production of waste textiles has increased rapidly in the past two decades along with rapid development economy, majority which been either landfilled or incinerated, resulting energy loss and environmental pollution. Microwave pyrolysis, can transform heterogeneous complex feedstocks into value-added products, is considered one most competitive technologies for processing textiles. However, achieving selective product formation during microwave pyrolysis remains a significant challenge. Herein, sodium acetate, potassium nickel acetate were introduced through an impregnation method as raw materials to improve efficiency. optimized process parameters indicated that had favorable promotional effect three acetates. Notably, containing 1.0% Ni exhibited highest gas rate, hydrogen-containing combustible reaching 81.1% 61.0%, respectively. Using X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier infrared spectroscopy (FTIR), Raman characterize before after it was found converted metallic (Ni0) pyrolysis. This active site significantly enhanced process, yield increased, disorder pyrolytic carbon also rose. proposed Ni0-enhanced mediated by offers novel efficient disposal simultaneous resource recovery

A promising method for converting greenhouse gases such as CO2 and CH4 into useful syngas is the dry reformation of methane (DRM). 5Ni-ZSM-5 2 wt.% Ce, Cs, Sr, Fe, Cu-promoted catalysts are investigated DRM at 700 °C under atmospheric pressure. The characterization, including XRD, TPR, TPD, TPO, N2 adsorption–desorption, TGA, TEM, Raman spectroscopy, revealed that catalyst’s active sites distributed throughout pore channels on surface, contributing to stability catalyst. Specifically, CO2-TPO followed by O2-TPO experiment using spent confirmed oxidizing capacity during reaction. Ce-promoted catalyst showed greatest increase in catalytic activity among other catalysts. 5Ni+2Ce-ZSM-5 exhibited twice concentration acid compared Cs-promoted counterpart, even though both achieved similar quantities basic sites. Without compromising H2 CO selectivity, this finding underscores crucial role enhancing conversion. With a GHSV 42,000 mL/(h.gcat), demonstrated impressive conversion rates 42% 70% 800 °C. reactants spend more time over subsequent reduction 21,000 resulting best performance with 80% 83% conversions.
