Selective Hydrogenation of 1-Hexyne Using Pd-Cu and Pd-W Supported on Alumina Catalysts

Chemical Engineering Transactions, 2013
Vinyl acetylene and 1-butyne are by products in mixed C4 separation processes and they must be eliminated due to their high flammability. However, C4 acetylene can be upgraded to higher value hydrocarbons such as 1,3-butadiene and 1-butene by using ...
