In Fushun research institute of petroleum and petrochemicals, status quo and development of paraffin wax hydrofining technology as well as study on new hydrofining catalyst were introduced. The process studies show that new spherical catalyst for paraffin wax hydrofining has good activity and stability. Carbonizable substances, polynuclear aromatics and stability of hydrofined products accord with food paraffin national standards.%介绍了FRIPP石蜡加氢技术概况以及新型石蜡加氢精制催化剂研制和工艺研究方面取得的新进展,工艺研究表明,新研制的球形石蜡加氢催化剂具有较好的活性和稳定性,加氢产品的易碳化物、稠环芳烃和安定性指标符合食品石蜡国家标准.
