报告介绍 | Abstract: In this lecture, I will cover two main topics: 1) Grace overview, and 2) Novel catalytic approach towards C4 olefins and gasoline octant in fluid catalytic cracking (FCC). Many refiners in North America have an economic incentive to produce more LPG olefins (preferably butylene’s) within the FCC product streams to serve as feed reactants in downstream alkylation processes in order to increase the octane value of the overall refinery gasoline pool. In this talk, we will discuss the reaction networks involved in acid-catalyzed light olefins formation, the variables that determine gasoline octane, and the ways by which Grace can exploit such pathways using novel catalytic solutions that increase butylene yield and octane value within the FCC unit. Such governing principles are validated by significant value uplifts within commercial operations that leverage these novel technologies. In recent years, Grace has commercialized several catalyst technologies, including ACHIEVE®400, ACHIEVE®400 Gold, and ACHIEVE®400 Prime. These solutions are producing high value alkylation feedstock, shifting product yields toward higher butylene to propylene ratio and rendering high-octane FCC gasoline. ACHIEVE®400 incorporates isomerization activity within the catalyst particle by using two different types of zeolites – a traditional Y zeolite and a specially tuned pentasil zeolite. Incorporation of isomerization activity into the particle itself results in a more desirable yield pattern than the use of a traditional ZSM-5 additive. About the speaker: Dr. Yuying Shu is a Senior Principal Scientist at W. R. Grace, located at Columbia in Maryland of USA. Before joining Grace, she had been an Associate Professor and group leader at Dalian Institute of Chemical Physics (2005-2006), a Visiting Scientist at Chemical Engineering Department of University of Delaware (2004-2005), a Research Associate at Chemical Engineering Department of Virginia Tech (2002-2004), a COE (Center of Excellence) Research Fellow and a NEDO Post-doctoral Researcher at Catalysis Research Center of Hokkaido University Japan (2000-2002). She received her Ph.D. in 2000 at Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Her major research interest is the development of new catalysts and new chemical reactions. Dr. Shu has worked in developing FCC catalysts and additives for many years and has become an expert in this field. She has filed 30 patents, and many were granted, including 7 granted US patents. She has published over 70 peer-reviewed journal articles and has given many conferences and invited lectures. She has received many awards including most recent one "2020 GATE” (the Grace Award for Technical Excellence, Grace's most prestigious scientific award), “2018-2020 Premier Awards” (Grace's most prestigious company-wide recognition of performance excellence), "Top Innovator of The Year for 2010 in Maryland”. She has made many significant contributions to Grace Catalysts Technologies and successfully led the efforts to the discovery of ten commercial catalysts and catalyst platforms. |
