Deep Hydrodesulfurization Catalysis and Process
Abstract
Driven by the growing demand for ultraclean fuels and the increasing
use of heavy oils, sulfur removal from fossil oils has received and
will continue to attract much attention in the coming years. Tremendous
efforts have been expended on the discovery and development of new
catalysts for hydrodesulfurization (HDS) process. This talk aims to
identify limiting factors bearing on the chemistry and catalysis in
deep HDS. The emphasis is on low-pressure operations. Among the topics
discussed are reactivity-property relationships, catalyst
functionalities, organonitrogen inhibiting effects, quantification of
active sites via transient experiments, and catalyst/process
synergisms.
