Sludge pyrolysis oil has the potential to substitute for refinery petroleum products for its similar characters with petroleum. In this study, the diesel-like fraction, with high heating value and low sulfur content compared with sludge pyrolysis oil, was obtained from sludge pyrolysis oil which was processed by two-step distillation to remove volatile component and compounds with high boiling points. The chemical composition of diesel-like fraction was investigated by Gas Chromatograph / Mass Spectrometer. The results indicated that this part comprises compounds containing N and O element 48.3% and hydrocarbons 51.7%, the hydrocarbon chain length of the alkanes and alkenes distributes across the C10~C20 mass range in the latter which was close to that of diesel. The sulfur content of diesel-like fraction is 10 times higher than that of diesel, and other fuel characters were similar with that of diesel, which indicated that diesel-like fraction was promising to substitute for diesel. After adding 10% diesel-like fraction into 5 # diesel, the fuel characters of diesel changed so little that it did not influence the application of diesel, which would be significant to alleviate the shortage of petroleum.

The article presents the characteristics of characteristic oils of the Apsheron oil and gas region, as well as the hydrocarbon composition of light and oil fractions. Oils of the Apsheron oil and gas region in terms of light fractions, sulfur content, and density are comparable to marketing grades of oils. The standards for prices are: graded crude oil WTI, Light Sweet, Brent, and Russian oils Sokol, Urals, Siberian Light are approaching them. We have studied in detail the yields and hydrocarbon composition of light and oil fractions of oils from the Apsheron oil and gas region. To obtain oils with a high viscosity index, studies were carried out to change the structure of oil fractions using hydrogen using the example of oil fractions of Azeri oil. Due to the significant content of aromatic hydrocarbons, schemes for the processing of oil fractions have been developed, including selective purification of distillates, dewaxing (except for Guneshli oil), as well as hydrocatalytic treatment in a severe mode in the presence of industrial Russian catalysts. As a result, it was possible to obtain API group I oils, according to the viscosity classification corresponding to SAE 20 and SAE 30. Thus, a study of the qualities and hydrocarbon composition of oils from the Absheron oil and gas region showed that these oils are characterized by a high content of light fractions, low density, and low sulfur content. According to these indicators, these oils correspond to the marker oils. In order to obtain base oils with a viscosity index of ≥90 and an aromatic hydrocarbon content of ≥10, a traditional refining method was used: selective refining, dewaxing, and severe hydrotreating.

Torsional Properties

The mechanical properties in torsion of single wool fibers of biologically produced high- and low-sulfur content have been studied to determine the effects on torsional behavior. The modulus of rigidity and the torsional relaxation, i.e., the decay in torque with time at a constant degree of twist, were determined in fibers tested in glycerol (~0% RH), distilled water, and aqueous solutions of HCl at pH 0.8, 1.8, and 2.9. The sulfur content had no significant effect on the modulus of ridigidy or on the magnitude of the torsional relaxation of dry fibers. Again, for fibers tested in distilled water, no significant effect of sulfur content on the modulus of rigidity was observed, but the percent decay in torque was measurably affected. The decay in torque in 1 hr for fibers of normal wool amounted to 23% of the initial torque and that for fibers of sulfur-enriched wool amounted to 15%. This difference in torsional relaxation behavior of wet fibers of the two wools was not thought to be due to the difference in sulfur content but may partly be linked with the aspartic acid content of the two wools. The modulus of rigidity and the torsional relaxation of fibers in aqueous HCl decreased with decreasing pH to as little as one third of the values obtained in distilled water, presumably due to the breaking of salt links, the decrease being greater for the sulfur-enriched wools.

. The article deals with the problem of environmental pollution in the town of Usolye-Sibirskaya CHPP-11, which operates on the Zabituiskoye coal coals, which have an increased sulfur content (4,1%) and ash (23,0%). It is proposed to replace coal from the Zabituiskoye field with coal of the BZR grade of the Tulun section with reduced ash content, low sulfur content and good calorific value.

The ultra-low sulfur diesel (ULSD) is required to comply with stricter government policy on low sulfur content of transportation fuels. Better knowledge of the different factors that concern deep desulfurization of fuels is necessary to achieve ultra-low sulfur content and cheaper way of producing ULSD. Both the capital and operating cost of the adsorptive desulfurization process is cheaper compare to the conventional hydroprocessing. In the future, the need to produce more volume of fuels with very low sulphur content from low-grade feedstocks like heavy oil and light cycle oil in order to meet up with the global demand for sulphur-free fuels is pertinent. Several on-going researches are pointing to the use of adsorbents for removal of sulfur compounds from hydrocarbon refining stream. In this chapter, varieties of carbon nanomaterials suitable for adsorptive desulfurization are discussed. If the active lifetime, where the capacity of the adsorbents are adequate, the approach is practically feasible for commercial application.
