摘 要：The conversion of glycerol to acrylic acid was carried out by the one-pot process *** catalyst used in this conversion is Cu-modified HY zeolite synthesized using pro-analytical precursors and alternative precursors from natural resources i.e.,Indonesian natural zeolite and *** crystal structure and physicochemical properties of catalysts were determined by various characterization techniques such as XRD,FTIR,SEM-EDX,TEM,SAA,and TPD-NH_(3).Based on XRD analysis,it shows that HY and CuHY,both from synthetic and alternative precursors,are confirmed to have typical peaks of Y *** mapping images show a uniform distribution of Cu on the HY *** addition,the TEM analysis also shows uniform particle size *** results of catalytic glycerol conversion show that Cu-modified HY catalysts give a higher acrylic acid yield than *** results also show that the highest yield of acrylic acid was obtained in 27.5%and 25.8%at a dehydration time of 3 h using pro-analytical and natural resources CuHY catalyst,*** Cu-modified HY catalysts having weak acid sites show the best catalytic activity in the conversion of glycerol to acrylic acid.
