延长渣油加氢装置运转周期的 RHT 技术及其工业应用

摘要

By deep analysis of the catalyst deactivation mechanism and reasons for pressure drop and catalyst bed hot point,RHT residue hydrodesulfurization technology with long operation cycle is devel-oped and applied. Series catalysts with good anti-carbon deposition and high capacity for metal deposi-tion were developed. RHT series catalyst showed good activity and excellent activity stability in many industrial applications and created huge economic efficiency for refineries.%通过研制抗积炭和脱金属、容金属能力高的催化剂，进行合理的级配装填，并控制反应器压差过早上升和热点过早出现，中国石化石油化工科学研究院开发了能显著延长操作周期的渣油加氢处理（RHT）技术及 RHT 系列渣油加氢催化剂。在多套渣油加氢装置的工业应用中，RHT 系列催化剂不仅表现出良好的活性，更表现出了优异的活性稳定性，延长渣油加氢装置的运转周期，为炼油厂创造了巨大的经济效益。
