2021-12-13  Published January 1969. This report is concerned with technology and costs for the desulfurization of petroleum stocks. Although the hydrodesulfurization of light and middle distillates such as gasoline, naphtha, kerosene, and gas oil is also evaluated, the emphasis here is on sulfur removal from the resid- ual fuel oil where there is a growing concern today because of air pollution.

Sulfur in Petroleum: Petroleum Desulfurization Techniques

Thus, petroleum desulfurization is a challenging task for the refiners under the current environmental regulations. Keeping in view this scenario, worldwide researchers are striving to develop new desulfurization techniques that are cost effective and more efficient than HDS. In this regard, several new techniques for desulfurization of

Chemical desulfurization of petroleum fractions for ultra

2009-4-1  An improved desulfurization process for removing sulfur from hydro treated diesel oil based on the oxidation of thiophenic type sulfur-containing compounds with H 2 O 2 and acetic acid (AcOH) using H 2 SO 4 as catalyst has been studied. The experimental results show that the sulfone content in the oxidation product increased rapidly with an increase in acetic acid and sulfuric acid ratios from

Desulfurization of high sulfur petroleum coke by molten

2019-6-1  Abstract. Desulfurization by molten caustic leaching (MCL) at 400–500 °C has been investigated in order to reduce the sulfur content of petroleum coke. Effective parameters on desulfurization of petroleum coke, other than temperature, include alkali to feed (petroleum coke) mass ratio, time and mesh size in the ranges of 0.5–1.5, 1–3 h

2021-11-27  The term deep desulfurization refers to the removal of 90 to nearly 100% of the sulfur contained in the petroleum fraction. This corresponds to an average product sulfur level of 25 ppm in naphthas, 0.1 wt% in gas oils, and 0.3 wt% in residual fuel oils. These low sulfur contents are dictated by increasingly stringent government regulations.

Desulfurization of petroleum fractions by oxidation and solvent extraction. The known ability of several solvents to extract sulfur compounds selectively from petroleum fractions can be dramatically improved by oxidizing the sulfur from the divalent state (sulfide) to the hexavalent (sulfone). The oxidation process itself leads to the removal

Microbial desulfurization of organic sulfur compounds in

Several microorganisms were found to desulfurize dibenzothiophene (DBT), a representative of the organic sulfur compounds in petroleum, forming a sulfur-free compound, 2-hydroxybiphenyl. They are promising as biocatalysts in the microbial desulfurization of petroleum because without assimilation of the carbon content, they remove only sulfur
