出光兴产株式会社开发了用于固定床渣油（渣油）加氢脱硫（HDS）装置的含铁（Fe）沸石催化剂。该催化剂名为 R-HYC，通过增加中间馏分油并同时减少塔底燃料油，表现出高渣油加氢裂化 (HYC) 活性。渣油 HDS 装置的商业应用已于 20 世纪 80 年代至 90 年代实现。由于R-HYC的HDS活性相对较低，因此该催化剂已被商业HDS催化剂取代，以应对近年来的降硫法规。为了满足当前炼油厂的需求，例如应对油价飙升和作为主要能源的燃料油市场萎缩，我们重新开发了新型R-HYC催化剂，该催化剂应具有良好的HYC和HDS能力。为了更实际地适用于现有的常压渣油脱硫（ARDS）装置，R-HYC催化剂与传统加氢处理催化剂（例如加氢脱金属（HDM）和HDS）的合适组合正在研究中。
Idemitsu Kosan Co., Ltd. had developed the iron (Fe) containing zeolite catalysts for the fixed bed residual oil (resid) hydrodesulfurization (HDS) unit. The catalysts, named R-HYC, showed high resid hydrocracking (HYC) activity by increasing the middle distillates and concurrently decreasing the bottom fuel oil. Commercial application with resid HDS units had been realized in 1980s–1990s. Because of relatively less HDS activity of R-HYC, the catalyst has been replaced with commercial HDS catalysts to correspond the lowering sulphur regulation in recent years. In order to meet the present demands on refineries, such as coping with the soaring oil price and shrinking market for fuel oil as the primary energy sources, we resumed developing new R-HYC catalysts, which should have good abilities in both HYC and HDS. For more practical purpose to be applicable to the existing atmospheric residue desulfurization (ARDS) unit, a suitable combination for the R-HYC catalyst with the conventional hydrotreating catalysts, such as hydrodemetallization (HDM) and HDS, has been under investigation.
