In a previous study, the effect of the nanosize of NiO particles on its surface properties for the Quinolin-65 (Q-65) adsorption from toluene-based solution has been investigated and well established. In this work, the effect of nanosize of NiO particles on the catalytic thermo-oxidative decomposition of the adsorbed Q-65 was investigated using TGA/DTA and TGA-MS systems.Virgin Q-65 and Q-65 adsorbed...
In a previous study, we showed that Ni–Pd bimetallic nanocatalysts supported on fumed silica had better adsorption affinity and catalytic activity toward adsorption and post-adsorption decomposition of asphaltenes compared to the support without functionalization. In this study, the effect of oxide support types on the adsorption and subsequent steam gasification of adsorbed asphaltenes was studied...
Thermally cracked asphaltenes from Athabasca vacuum residue produced at four different process severities were investigated for adsorption and subsequent catalytic oxidation. Fe 3 O 4 nanoparticles were used for the removal of these four different thermally cracked asphaltenes from toluene solutions by a batch-adsorption technique followed by subsequent catalytic oxidation. Asphaltene...
A robust setup has been developed that permits determination of microcarbon residue (MCR) with high accuracy and precision, in as many as 26 petroleum materials at a time. The method requires usage of very small quantity of sample (mg). The effect of gas flow rate and sample vial size in our setup is presented. Effect of presence of small amounts of air during heating is also studied. The general...
