The microstructure of petroleum vacuum residue films for bituminous concrete: a microscopy approach.
Selected carbon-rich refinery residues ('binders') mixed with mineral particles can form composite materials ('bituminous concrete') with bulk mechanical properties comparable to those of cement concrete. The microstructural mechanism underlying the remarkable composite properties has been related to the appearance of a rigid percolating network consisting of asphaltenes and mineral particles [...
متن کاملSample preparation procedure for the determination of polycyclic aromatic hydrocarbons in petroleum vacuum residue and bitumen
This paper describes a novel method of sample preparation for the determination of trace concentrations of polycyclic aromatic hydrocarbons (PAHs) in high-boiling petroleum products. Limits of quantitation of the investigated PAHs in materials of this type range from tens of nanograms per kilogram to <20 μg/kg. The studies revealed that in order to separate most of interferences from the analyt...
متن کاملCadmium removal using waste residue generated after recovery of base metals from manganese nodules
The laboratory scale investigations on Cd removal characteristics of waste manganese leach residue (wMNR), generated by reduction roasting – ammonia leaching of manganese nodules have been studied. Adsorption studies show rapid kinetics of Cd adsorption. About 90% of total Cd adsorption occurs within 15 min contact time and equilibrium is attained within 30 min. The quantity of Cd adsorption in...
متن کاملHeavy Metals Residue in Cultivated Mango Samples from Iran
Background: Heavy metals contaminations are recognized as the serious risk to our environment. The aim of the present study was to analyze heavy metals residue in cultivated mango samples from Iran. Methods: Totally, 72 mango samples were randomly collected among six different mango genotypes cultivated in Southern Iran from June to July 2015. Lead, chromium, cadmium, and arsenic were determin...
متن کاملbiosurfactants and their use in upgrading petroleum vacuum distillation residue: a review
it has been known for years that microbial surface active agents have a wide range of applications not only in oil spill environment but also in many industries. their properties including: (i) changing surface active phenomena, such as lowering of surface and interfacial tensions, (ii) wetting and penetrating actions, (iii) spreading, (iv) hydrophylicity and hydrophobicity actions, (v) microbi...
