Abstract

A novel experiment was carried out for the removal of organic sulphur by electron transfer process. In these experiments, the effect of conventional and microwave heating were investigated on desulfurization of organic sulphur. The aim of the study was formed soluble metal-organic sulfur bonds using Pd+2, Sn2+ and Sb3+ metal ions of variable valence state. In this way, it was tried to create a mechanism that cleavage the C-S bonds. Desulfurization is occur by breaking the aliphatic sulfur bonds of metal ions with high negative oxidation potential. As a result of the studies, the 24.30% of total sulfur was removed with Pd2+ ion. In microwave heating, it was determined that higher organic sulfur was removed in less leaching times.

Abstract

Bu Çalışmada, organik kükürdün elektron transfer işlemi ile uzaklaştırılması araştırılmıştır. Deneylerde, organik kükürdün uzaklaştırılmasında klasik ve mikrodalga ısıtma teknikleri kullanılmıştır. Çalışmada farklı değerlikli Pb, Sn ve Sb metal iyonları kullanılarak çözünebilir metal-organik kükürt bağlarının oluşturulması amaçlanmıştır. Bu sayede, C-S bağlarını parçalayan bir mekanizma oluşturulmaya çalışılmıştır. Böylece, yüksek negatif oksidasyon potansiyeline sahip metal iyonlarının alifatik sülfür bağlarının kırılmasıyla kükürt uzaklaştırma sağlanabilmiştir. Çalışmaların sonucunda toplam sülfürün %24.30'u Pd2+ iyonu ile uzaklaştırılmıştır. Ayrıca, mikrodalga ısıtmada, daha kısa zamanda daha yüksek organik sülfürün uzaklaştırıldığı belirlenmiştir.
