Biomass gasification produces syngas composed mainly of hydrogen, carbon monoxide, dioxide, methane, water, and higher hydrocarbons, till C4, ethane. The hydrocarbon content can be upgraded into richer hydrogen streams through the steam reforming reaction. This study assessed process at thermodynamic equilibrium five streams, with different compositions, from three biomass sources (Lignin, Miscanthus, Eucalyptus). simulations were performed on Aspen Plus V12 software using Gibbs energy...
The effect of La/AlZn/AlLa oxide supports on Ni-based catalysts performance was assessed for glycerol steam reforming renewable H2 production. NiAlLaOx showed the best providing a conversion into gaseous products 91 % and yield 5.40 molH2∙molG,in‐1 at 700 °C. Additionally, stability experiments lasting up to 24h were performed 625 °C, having been observed stable behavior with low coke formation. materials physicochemical properties, determined from different techniques (ICP-OES, N2-sorption...
Solids with potential application in tyrosol (Ty) removal by photo–Fenton processes have been synthesized using aluminum salt cake as a source. Two series of hydrocalumite layered double hydroxides (LDH) were synthesized: one containing structural Fe3+ (occupying octahedral positions the LDH) and another surface impregnated Fe3+; all solids calcined air at 750 ºC. The characterized powder X–ray diffraction, FT–infrared spectroscopy, thermal analysis, N2 adsorption–desorption isotherms –196...
Distillery wastewater (DW) is a byproduct of the wine distillery industry, posing environmental challenges due to its pollutant nature and costly disposal. This study investigates steam reforming as method for treating valorizing DW by removing pollutants while generating renewable hydrogen. Traditional (TR) autothermal (ATR − combining partial oxidation) processes are explored across varying compositions (mix 1–5) derived from lees, pomace, wine. Simulations performed under different...
In this work, in-house synthesized NiMgAl, Ru/NiMgAl, and Ru/SiO2 catalysts a commercial ruthenium-containing material (Ru/Al2O3com.) were tested for CO2 methanation at 250, 300, 350 °C (weight hourly space velocity, WHSV, of 2400 mLN,CO2·g−1·h−1). Materials compared in terms conversion CH4 selectivity. Still, their performances assessed short stability test (24 h) performed °C. All characterized by temperature programmed reduction (TPR), X-ray diffraction (XRD), N2 physisorption −196 °C,...
