本文介绍了ＶＲＤＳ－ＦＣＣ组合工艺的开发过程及工艺特点。通过对孤岛减压渣油加氢脱硫产品（ＨＶＲ─低硫重质燃料油）理化性质的研究，对全厂催化裂化原料的总体优化调配，对催化剂的评选和操作条件的确认，并在工业装置和实验室小型ＦＣＣ装置进行了掺炼ＨＶＲ的探索性试验，确立了ＶＲＤＳＦＣＣ组合工艺，纳入了大型工业装置的正式运行行列。为拓宽催化裂化原料，提高原油加工深度，提高企业经济效益方面发挥了巨大作用。
This article describes the VRDS-FCC combination process development process and process characteristics. Through the study of physical and chemical properties of isolated island hydrodesulfurization products (HVR - low sulfur heavy fuel oil), the overall optimization and deployment of FCCU raw materials, the selection of catalysts and the confirmation of operating conditions, Devices and lab-scale FCC units were exploratory experiments on HVR blending and the VRDSFCC combination process was established to include the formal operation of large industrial installations. In order to broaden the catalytic cracking of raw materials, increase the depth of crude oil processing, improve the economic efficiency of enterprises has played a significant role.
