Abstract
A catalyst composition and a method for the transalkylation of heavy aromatics includes core-shell mesoporous silica-beta zeolite (BZ@MSi) composite particles including a mesoporous silica (MSi) shell, a beta zeolite (BZ) core particle, and nickel (Ni). The mesoporous silica shell encompasses the BZ core particle, with a thickness ranging from 10 nm to 100 nm. The thickness of the mesoporous silica shell is ranges from 10 nm to 100 nm. Further, Ni is dispersed over the BZ@MSi composite particles in an amount ranging from 0.1 wt. % to 10 wt. % relative to the total weight of the BZ@MSi composite particles.
