【摘要】 在进行粗萘加氢精制时,要求催化剂具有高活性和良好的选择性。即脱硫、脱氮等精制活性高,而萘加氢生成四氢萘的量要少。我们自制了一种以大孔氧化铝作载体的Co-Mo-Al型催化剂,在适宜的工艺条件下可以满足上述要求,同时催化剂上积炭也不高,是一种较为理想的加氢精制用催化剂。更多还原

【Abstract】 In the hydrofining of raw naphthalene, attempts were made both to suppress the excessive formation of tetralin and to achieve satisfactory desulfurization with least fouling of catalyst.By the use of a new catalyst at appropriate reaction condition, it was found that tetralin was as low as 4.20% and S content at 18.8ppm in the product and the coke formation was low on the catalyst.更多还原
