Catalytic deoxygenation of neat stearic acid was studied at 360 °C under 10 bar argon or 5 vol % hydrogen in a fixed-bed reactor (down flow) using mesoporous-supported Pd/C (Sibunit) beads as catalyst. The results showed stable catalyst performance, giving about 15% conversion level acid. main liquid-phase product heptadecane, while the gaseous products were CO and CO2.
Dry reforming of methane (DRM) is a promising method to utilize two greenhouse gases, such as CH4 and CO2, produce synthesis gas. In the current work, both monometallic Ni bimetallic Ni–Fe catalysts with different Fe/Ni molar ratios, synthesized by solution combustion (SCS) in DRM, were investigated using feed ratio CH4/CO2/Ar 1:1:1 at 600–900 °C. The characterized several physicochemical techniques X-ray diffraction (XRD), scanning electron microscopy energy-dispersive (SEM-EDX)...
The catalytic oxidation of arabinose to arabinonic acid was investigated in a recycled packed bed reactor address pH control issues continuous processes. Packed reactors are pivotal the valorization biomass, making shift from batch systems critical for industrial applications. setup used 2.1% Au/γ-alumina catalyst extrudates and incorporated tandem system with liquid recycling loop maintain controlled 8, ensuring optimal reaction conditions. Experiments were conducted at temperature 70 °C,...
Carbon-supported mono- and bimetallic catalysts prepared via incipient wetness impregnation were systematically studied in aqueous-phase reforming (APR) of xylitol aiming at hydrogen production from biomass. The catalytic performance several VIII group metals their combinations, such as Pt, Ni, Pt-Ni, Re, Pt-Re, Ru, Pt-Ru, Pt-Co, was compared for APR a fixed-bed reactor 225 °C 29.7 bar (N2). Ni/C, Ru/C, Re/C displayed significantly lower activity to others. Activity selectivity H2 Pt-Ni/C,...
Isomerization of glucose, galactose and arabinose to corresponding keto-sugars was studied in the present work over a range heterogeneous catalysts.
Hydrodeoxygenation (HDO) of isoeugenol was investigated over several Ni (Ni/SiO2, Ni/graphite) and Co (Co/SBA-15, Co/SiO2, Co/TiO2, Co/Al2O3) catalysts at 200 300 °C under 30 bar hydrogen pressure in a batch reactor.
