前言石脑油催化重整的催化剂,自1949年美国UOP公司开发了铂催化剂以后,铂—卤素—氧化铝催化剂在约廿年的时间内成为重整催化剂的主流,铂重整催化剂虽然有较好的活性、稳定性和选择性,但不能满足高辛烷值汽油和高芳产的要求。1968年出现了铂—铼双金属重整催化剂,它具有稳定性好,容碳能力高,低压低氢油比下产品收率高和辛烷值高的特点。因此,铂—铼催化剂的出现引起了催化重整第二次划 Introduction Catalyst for catalytic reforming of naphtha Since the platinum catalyst was developed by the UOP Company in the United States in 1949, the platinum-halogen-alumina catalyst has become the mainstream of the reforming catalyst in about 20 years. Although the catalyst for the reforming of platinum Good activity, stability and selectivity, but can not meet the high octane gasoline and high aromatic requirements. The platinum-rhenium bimetallic reforming catalyst appeared in 1968. It has the characteristics of good stability, high capacity of carbon content, high yield of products under low pressure and low hydrogen oil ratio and high octane number. Therefore, the emergence of platinum-rhenium catalyst caused the second draw of catalytic reforming
