Springer Diameter-Transformed Fluidized Bed: Fundamentals and Practice: 27 (Particle Technology Series, 27)

This book puts forward the concept of the Diameter-Transformed Fluidized Bed (DTFB): a fluidized bed characterized by the coexistence of multiple flow regimes and reaction zones, achieved by transforming the bed into several sections of different diameters. It reviews fundamental aspects, including computational fluid dynamics simulations and industrial practices in connection with DTFB. In particular, it highlights an example concerning the development of maximizing iso-paraffins (MIP) reactors for regulating complex, fluid catalytic cracking reactions in petroleum refineries. The book is a must-have for understanding how academic and industrial researchers are now collaborating in order to develop novel catalytic processes.

About the Author Youhao Xu received his BSc in 1985 and MSc in 1988 from East China University of Science and Technology. Thereafter, he received a PhD in 2006 from the Research Institute of Petroleum Processing (RIPP) of Sinopec. Currently, he is a Chief Scientist at Sinopec in the field of petroleum refining. He has over 30 years’ experience in research and development in fluid catalytic cracking (FCC) processes and invented the diameter-transformed fluidised bed reactor. He has enabled effective regulation of complex gas-solid catalytic reactions by establishing the fluidised bed reactor platform and by recognising the coexistence of multiple temperature zones and multiple flow regimes in a single reactor. Based on this platform, several technologies have been developed such as high heavy hydrocarbon utilisation, clean gasoline production and light olefin production. He proposed the concept of two reaction zones for cracking and conversion reactions (i.e., isomerisation and hydrogen transfer), and thus invented the MIP (maximising iso-paraffins) process. He correlated coke yield and conversion, and thereafter developed a catalytic cracking-hydrogenation integrated process for the highly effective conversion of heavy hydrocarbons. The above processes have been applied in 115 commercial units with an annual capacity totalling 154 million tons, accounting for 81% of all FCC units in China and providing 57% of gasoline for Chinese vehicles. Currently, 84% of FCC units in Sinopec facilities utilise the diameter-transformed fluidised bed reactor. Youhao Xu has been the recipient of numerous awards including the: 1) State Scientific and Technological Progress Award (twice), Second Class; 2) China Patent Gold Award; 3) China Patent Excellence Award (twice); 4) Sinopec Technological Invention Award, First Class; 5) Sinopec Scientific and Technological Progress Extra Award; 6) Sinopec Scientific and Technological Progress Awards (three times), First Class once, Second Class twice; 7) China Youth Science and Technology Award in 2006; 8) the first Sinopec Scientific and Technological innovation Merit Award (one of two winners). He holds 194 Chinese patents and 58 international patents and has published 103 papers having 1,470 citations. He authored the monograph “Catalytic Cracking Chemistry and Process”, co-authored the monograph “Diameter-Transformed Fluidized Bed: Fundamentals and Practice”, both in Chinese, and co-
