New insights on oxidative desulfurization for low sulfur residual oil production

Abstract

Combustion of heavy fuel oils releases sulfur oxides (SOx) which are known to be harmful for human health, causing various types of diseases, also contribute to acid rain. International Maritime...

Fractal growth of a fern-like nanostructured Cu2O film electrode for electrochemical reduction of CO2 to ethanol

“…shows constant deposition current except in the case of CuP5T5 where a slight drop is observed over a period of deposition time. 3…”

“…The acceleration of anthropogenic pollutant CO 2 gas to the surfeit level has highlighted the urgent need to develop techniques to circumvent the issue. [1][2][3][4] Reduction of CO 2 has been achieved by various methods including thermochemical, 5,6 photocatalytic, [7][8][9] electrochemical, [10][11][12] and photo-electrochemical. 13,14 CO 2 conversion to obtain value-added products by an electrochemical approach is regarded as a promising and cost-effective strategy to recycle it and simultaneously address the global energy demand.…”

“…In electrodeposition, particle growth, surface structure, morphology and the oxidation state of the deposited copper layers can be controlled by tuning the potential and duration of the deposition. 3,[35][36][37][38] It has been noted that random morphological arrangement makes it difficult to explain the direct relationship between the morphology and ECO 2 R. 3 To understand the morphology variation and its effect on CO 2 reduction, Gao et al studied three bismuth catalysts with different morphologies and their effect on the reduction efficiency of CO 2 . They found that among the three bismuth catalysts, 2D bismuth nanosheets show better performance (85%) over bismuth nanowires and nanospheres.…”

Catalytic Aquathermolysis of Emulsified Residual Oils with Naphthenates

“…Fossil fuels are expected to remain the predominant source of global energy for many decades due to their exceptional quality. − Countries worldwide are placing high expectations on the advanced processing and treatment of oil and gas resources, as well as the recycling of byproducts, to meet the growing demands associated with economic development and technological progress. − Residual oil, a byproduct of petroleum refining, poses challenges with a large density, high viscosity, elevated sulfur content, and poor mobility. Transporting residual oil is difficult, making the reduction of viscosity and desulfurization crucial, especially for its potential use in blending marine fuel oil. − …”
