What are the Challenges in Ultra Deep Desulfurization?
One of the primary challenges is the removal of refractory sulfur compounds such as thiophenes, benzothiophenes, and dibenzothiophenes, which are more resistant to conventional desulfurization methods. Another challenge is maintaining the balance between high desulfurization efficiency and the preservation of fuel quality, as severe conditions can lead to undesirable side reactions and loss of valuable hydrocarbons.
