FCC-benzinekben lévô egyedi olefinek átalakulásának vizsgálata a hidrogénezô kéntelenítés körülményei között
During heterogeneous catalytic desulphurization of FCC gasoline (full range or heavy FCC gasoline) many chemical reactions take place apart from the main reactions. Thus the hydrocarbon composition of the final product changes which significantly influences other important properties (e.g.: researchand motor octane number, storage stability etc.) of the product. In the paper conversion of individual olefins and its effect on the octane number was investigated in a laboratory scale reactor system.Tovább
