the objective of this research is to find an economically attractive alternative method for hydrodesulfurization of petroleum fractions and to select a suitable adsorbent for this process.deep desulfurization of transportation fuels (gasoline, diesel, and jet fuels) is being mandated by governments and is also needed for future fuel cell applications. however, it is extremely difficult and cost...

in this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in esr processing has been investigated.the chemical composition and microstructure studies were evaluated, using spectrophotometer,omand edx analyses attached to sem.the results show that esr process has successfully reduced the amount and size of inclusions. in some c...

In recent years, biological desulfurization technology has attracted more and attention from domestic foreign researchers due to its mild reaction conditions, high efficiency, environmental protection. this study, bacteria were collected oil depots, sewage treatment plants sewage, using a screening medium with DBT as the only sulfur source. Three strains that can degrade isolated, numbered 1, 2...

With the enlarging of industrial desulfurization, the amount of FGD gypsum is increasing rapidly. The preparation of alpha-calcium sulfate hemihydrate (α-HH) is one of the biggest concerns for FGD gypsum reclamation. The influence of mixed chlorate solution of Mg-Ca-Na concentrations (5-30 wt%) and FGD gypsum concentrations(5-30 wt%) by hydrothermal salt solution method at atmospheric were inve...

The disposal of sulfur compounds from fossil fuels in general and diesel particularly has been stimulated worldwide due to their harmful environmental emissions during the combustion process. Several desulfurization techniques can be employed; however, photocatalytic considered as safest cost-effective route achieve such goal. This study introduces a novel hybrid photocatalyst made coupling bot...
