Catalytic and Process Study of the Selective Hydrogenation of Acetylene and 1, 3-butadiene (Hardcover)
About this item
The thesis offers novel methods for catalyst and process design for the selective hydrogenation of acetylene and 1,3-butadiene. The author predicts the properties of supported Pd-Ni bimetallic catalysts using density functional theory (DFT) calculations and temperature-programmed desorption (TPD). The excellent correlation between model surfaces and supported catalysts demonstrates the feasibility of designing effective bimetallic catalysts for selective hydrogenation reactions. The author also proposes a method to design non-precious metal catalysts to replace precious metals. Meanwhile, the process of selective hydrogenation of acetylene is modified by coupling the selective adsorption to the selective hydrogenation in liquid phase, and the ethylene selectivity is greatly improved while the heat transfer is greatly enhanced. By analyzing the mechanism of liquid-phase hydrogenation, the author proposes a multi-stage slurry bed reactor for industrial application.
