As one of the most abundant metals in heavy oils, Ni has suffered so notably increasing impacts from industrial and traffic activities that anthropogenic Ni emissions have altered natural geochemical processes. The coral Ni/Ca has become a reliable…
Petroleum coke is industrial solid wastes and its disposal and storage has been a great challenge to the environment. In this study, petroleum coke was utilized as a novel co-reduction reductant of low-grade laterite ore and red mud. A ferronickel…
In this work, NiFe nanocatalysts with different molar ratios 1:0.33, 1:1 and 1:3 were synthesized by a modified inverse microemulsion method at Soft Chemistry conditions in order to apply them to heavy crude oil (HCO) in situ hydroprocessing and to…
In this work, nanocatalysts as Ni, Mo, Fe nanoparticles (NPs) were synthesized by the modified inverse microemulsion method at room temperature conditions in order to apply them to heavy crude oil (HCO) in situ hydroprocessing and to improve their…

A method combining ultracentrifugation and cloud point extraction is proposed for the separation and determination of Fe, Ni and V porphyrins in crude oil. An emulsion containing about 200 mg of crude oil, 6% (w v1) of Triton X-100, 1.6% (v v1) of…
To efficiently remove Ni from crude oils and also without corrosion occurring in the process, polymer brush with core-shell structure (PAA@SiO2) was synthesized by radical polymerization, in which micro-sized SiO2 as the core and polyacrylic acid as…
Through silane coupling and free radical polymerization, using SiO2 as core and poly4-vinylpyridine (P4VP) as shell, polymer brush with core-shell structure (P4VP@SiO2) was designed and synthesized. The structure of P4VP@SiO2 was further…
Palm oil is the vegetable oil refined and modified in the largest amount. In this study, we present the effect of wet fractionation and hydrogenation of RBD palm oil on the removal of 3-MCPD and glycidyl esters. Fractionated palmstearins had…
Abstract: General features of the distribution of vanadium and nickel in the products of two-step solvent fractionation of asphaltenes have been using the exampley of heavy crude oils from various fields of the VolgaUrals oil-and-gas basin (Russia).…

In a study to determine whether or not the Northeast Monsoon has a major effect on the distribution of metals in sediments, total Al, Cr, Fe, Mn, Ni, Pb and Zn were measured in twenty six surface sediment samples were collected from the South China…
Deoxygenation of pyrolysis vapor from palm fruit cake by different catalysts was prior investigated by using Ni/γ-Al2O3, Mo/γ-Al2O3, and NiMo/γ-Al2O3 prepared by wet impregnation method. NiMo/γ-Al2O3 showing the highest degree of deoxygenation (%DOD)…
A single-step new route has been developed to synthesize 2-pentanone from biomass-derived furfural via simultaneous hydrodeoxygenation (HDO), ring-opening (RO) and hydrogenation reactions over a bi-metallic Cu–Ni/SBA-15 catalyst in a fixed-bed…
Petroleum coke is a potential source of vanadium (V), nickel (Ni), and molybdenum (Mo) to water resources in Athabasca Oil Sands Region (AOSR) of northern Alberta, Canada. Large stockpiles of this bitumen upgrading byproduct will be incorporated into…

Once again in this chapter, we revisit the tension between preserving the Arctic and developing its resources for financial gain, national power and prestige, and geopolitical place marking. As we will see, some governments are far more interested in…
A series of nickel-magnesium mixed oxides (NiMg) of varying molar ratios, Ni9Mg, Ni2Mg, NiMg, NiMg2 and NiMg9, were synthesized using the co-precipitation technique. These materials were prepared as possible lower cost alternatives to Pd-based…
