Witryna5 lis 2009 · The influence of indium on the properties of Pt–Re/Al2O3 catalysts used in naphtha reforming is studied. The addition of indium to the Pt–Re/Al2O3 catalyst produces a big decrease of acidity. It also produces an inhibition of the metal function, i.e., dehydrogenation and hydrogenolysis activity. The reaction of n-C5 isomerization … Witryna15 wrz 2024 · The first catalytic naphtha reforming came into practice at the start of World War II. It used a bed of catalyst to improve the yields by not just cracking non-aromatics out of the naphtha but also by changing some of the non-aromatics into aromatics. The catalyst used was a single base metal oxide on an inert support. fodmap onion garlic
