Crude oil; is a fossil fuel containing carbon, hydrogen, sulfur and many other components one of the world's largest most widely used energy sources. However, in order for crude oil to be as an source, it must refined. With use petroleum products obtained result refining, very high amounts SOx gas are released into atmosphere. These gases seriously harm both environment human health. This study...

Microbial Enhanced Oil Recovery (MEOR) is a potential technology for residual heavy oil recovery. Many heavy oil fields in Oman and elsewhere have difficulty in crude oil recovery because it is expensive due to its high viscosity. Indigenous microbes are capable of improving the fluidity of heavy oil, by changing its high viscosity and producing lighter oil fractions. Many spore-forming bacteri...

gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...

This article contains errors in the units used for carrier mobility. In Fig. 2a–d, the units on the y axis should be ‘cm2V 1s 1’ not ‘V 1s 1cm 1’. Similarly, the second and third sentences of the second paragraph of the ‘Quantum yield calculation’ section should read ‘From Fig. 2 and Table 1, we obtain fm(1þ c1)1⁄4 11 cm2V 1s 1 and fk21⁄4 11 10 10 cm3s 1. These data compare well with the corres...

An alomina-based nano adsorbent was prepared by modification of the external surface of γ-alumina (γ-Al2O3) nanoparticles with functional groups of a new Schiff base 4-[(2-hydroxy-3-methoxy-benzylidene)-amino]-5-methyl-2,4-dihydro-[1,2.4]triazole-3-thione] “L”. In order to the removal of Cr(VI) from aqueous solutions, we used the reaction of the sodium dodecyl sulfate coated nano-alumina with L...

In the present study, adsorption of Co(tsPc)-4 using γ-Alumina was investigated. γ-Alumina was prepared by gel combustion method. The XRD pattern revealed that the synthesized γ-Alumina is amorphous and SEM image showed its nanosize scale while BET surface area about 501 m2/g and pore size of 7 nm implies highly porous surface which is a characteristic property of a high-quality adsorbent. In t...

Spherical mesoporous silica MCM-41 was synthesized for adsorptive removal of sulfur compounds from fossil fuels using 1mM solution of dibenzothiophene (DBT) in dodecane as model oil. The prepared silica adsorbent has been characterized by nitrogen adsorption-desorption analysis as well as Small Angle X-ray Scattering (SAXS), and transmission and Scanning Electron Microscopy (SEM) methods. R...

Oxidative desulfurization of model oil and heavy fuel (HFO) was investigated under mild conditions using H2O2 as an oxidant acetonitrile extractant. The influence factors in the oxidation extraction processes were evaluated optimized. molecular characteristics raw feedstock desulfurized oils, corresponding phases systematically analyzed by APPI FT-ICR MS, 1H NMR, etc. results showed that rate d...

We show that small amounts of copolymer that decorate an oil/water interface can greatly enhance the stability of swollen surfactant hexagonal phases, comprising oil tubes regularly arranged in a water matrix. Both the radius of the tubes and the thickness of the aqueous channel between the tubes can be controlled independently over large ranges. Such soft composite materials offer a potential ...
