Steps:

Catalytic reaction study
To test the performance of the catalysts, the liquid-phase hydro-genation of 1-heptyne under mild reaction conditions was carriedout using approximately 5 mg of reduced catalyst dispersed in10 cm3reactant mixture of 1-heptyne (Aldrich) in toluene (2%v/v).The reaction was performed in a 100 cm3stainless steel autoclavereactor (JASCO, Tokyo, Japan) at a pressure of 4 bar H2and at tem-perature of 30C for 5-120 min. After that, the liquid product wascollected and analyzed by using gas chromatography equippedwith a flame ionization detector (FID) and GS-alumina capillary col-umn. The catalytic reaction tests were conducted under the absenceof mass transfer/diffusion resistance. The highest stirring speed(1000 rpm) was used to eliminate the external mass transfer resis-tance and the effect due to pore diffusion was minimized by usingsmall particle size catalysts. The catalysts were thoroughly grindedinto powder form prior to the reaction tests.
