This work aimed to evaluate the effect of niobium addition on nickel-based catalysts and their performance in dry reforming reactions to produce syngas (H and CO). Different quantities of NbO (5, 10, and 20% w/w) were used to prepare the catalysts, while a fixed content of Ni was applied (20%). The catalysts were supported on MCM-41.

Article Synopsis
- Upgrading biogas to biomethane is important for utilizing renewable fuels from biomass waste, and this study investigates the efficiency of coconut-shell activated carbon (CAC 8X30) for this process through Pressure Swing Adsorption (PSA).
- The research involved characterizing the adsorbent and estimating adsorption parameters for methane (CH), carbon monoxide (CO), and water (HO), comparing CAC 8X30 with zeolite 13X under different conditions.
- Results showed CAC 8X30 had significant micropore volume and demonstrated better selectivity for CO over CH in humid conditions, suggesting a potential combined use with zeolite 13X for effective biogas upgrading.

The Brazilian aviation industry is currently developing biofuel technologies that can maintain the operational and energy demands of the sector, while reducing the dependence on fossil fuels (mainly kerosene) and greenhouse gas emissions. The aim of the current research was to identify the major environmental, economic and social impacts arising from the production of aviation biofuels in Brazil. Despite the great potential of these fuels, there is a significant need for improved routes of production and specifically for lower production costs of these materials.
