Abstract |
A corona discharge hydrodesulfurization process was investigated for fuel oil containing 2.57% sulfur. A concentric tube, packed-bed reactor was used for the study. Up to 23% reduction in sulfur content, a linear relationship was shown between energy input to the oil and decrease in sulfur concentration. The energy required was too high to justify practical application of the process at its present state of development. Use of a desulfurization catalyst as a dielectric packing in the corona reactor improved the efficiency sixfold but reintroduced the problem of spent catalyst regeneration. In a separate short study, powdered bituminous coal was exposed to hydrogen in a corona discharge in the hope of converting FeS2 to magnetic FeS. (Author) |
