ABSTRACT

The supply of environmentally friendly petroleum products has extreme importance in ensuring a reliable healthy climate globally. The elimination of obstinate sulfur complexes is an enormous task in the current challenging legislative situation for fuel refining companies. The conversion of these obstinate sulfur complexes is challenging in the progression of deeper photocatalytic oxidative desulfurization. As an eco-friendly, inexpensive and non-lethal oxidant with bountiful accessibility, oxygen prevailing in the air is utilized in the deep photocatalytic oxidative desulfurization process as a reliable substitute for hydroperoxide and other expensive hydroperoxide derivatives. However, the superlative activation of oxygen under light irradiations is hitherto a challenge. This potential review critically analyzes the recent strategies employed for the development of efficient materials for the progression of deep aerobic photocatalytic oxidative desulfurization system for the removal of obstinate sulfur complexes. Furthermore, the associated technologies influencing the deep photocatalytic oxidative desulfurization performances have been identified and significant parameters for the process optimization are evaluated to address the forthcoming challenges.

摘要

环保石油产品的供应对于确保全球可靠的健康气候极为重要。在燃料精炼公司当前充满挑战的立法形势下，消除顽固的硫络合物是一项艰巨的任务。这些顽固的硫配合物的转化在更深层次的光催化氧化脱硫过程中具有挑战性。作为一种环保、廉价和非致命的氧化剂，空气中的氧气被广泛用于深度光催化氧化脱硫过程，作为氢过氧化物和其他昂贵的氢过氧化物衍生物的可靠替代品。然而，在光照射下氧的最高级活化仍然是一个挑战。这篇潜在的综述批判性地分析了最近用于开发有效材料的策略，以促进深度好氧光催化氧化脱硫系统去除顽固的硫配合物。此外，已经确定了影响深度光催化氧化脱硫性能的相关技术，并对工艺优化的重要参数进行了评估，以应对即将到来的挑战。
