摘要
开发出一种新型柴油催化氧化脱硫技术 ,在TS 2催化剂、空气氧化剂作用下 ,对柴油进行催化氧化脱硫 ,可有效地脱除柴油中的硫化物。在评选出的实验条件下 ,处理后的柴油硫质量分数从 15 0 0～ 160 0 μg/g降至 15 0μg/g以下 ,脱硫率和柴油收率分别达到 90 %和 97%以上 ,达到世界燃料规范Ⅱ类柴油硫含量标准。该法常压低温操作、无需氢源和H2 O2 氧化剂 ,克服了柴油加氢脱硫和H2 O2 氧化脱硫的缺点 。
A new diesel catalyzing-oxidizing desulfurization technology has been developed, and by the technology, sulfides in diesel have been evidently removed with TS-2 catalyst and air oxidant. Under the selected experimental conditions, sulfur content of the treated diesel has been reduced from 1 500-1 600 μg/g to below 150 μg/g, the desulfurization rate and diesel yield have researched 90% and 97% respectively, and the sulfur content standard of World Wide Fuel CharterⅡ has been met. The technology provides a new way to produce low sulfur content diesel at atmospheric pressure and low temperature without using hydrogen and hydrogen peroxide oxidant. As a result the shortcomings of diesel hydrodesulfurization and oxide-desulfurization have been overcome.
