| 1 | Kinetics and mechanistic study of n-alkane hydroisomerization reaction on Pt-doped g-alumina catalyst显示文摘The catalysts g-alumina(GA,the reference catalyst)and Pt doped g-alumina(PGA-s)were synthesized using a simple sol-gel technique,in which at first preparation of porous base(GA),then impregnation of platinum salt over the base and finally reduction of platinum in the surface of the support were done.These catalysts prepared in different mole ratios of Pt:Al as 2:1,1:1 and 1:2 are named as PGA-1,PGA-2 and PGA-3 respectively.The isomerization of n-alkanes(n-hexane,nheptane and n-octane)were investigated over the synthesized catalysts.The 2-methyl pentane(2-MP),2,2-dimethyl pentane(2,2-DMP)and 2,3-dimethyl hexane(2,3-DMH)are the major products of respective isomerization of n-hexane,n-heptane and n-octane,besides a small amount of other branched isomers are also produced.The product distribution is comparable to that reported for Pt based other catalysts.The optimal mole ratios of Pt:Al is 1:1(PGA-2)gives quite good catalytic activity for isomerization of n-alkane.Even through in reusability study,PGA-2 gives better performance than others.We have mainly focused on kinetic study,reaction mechanism behind isomerization and calculated the order of reactions and activation energies of the isomerization reactions in the present work. | Abhishek Dhar Rohit L.Vekariya Pushan Sharma | 2017 | Petroleum2017，3，4： | 1 |
