1. A catalyst system comprising:
a core comprising a ZSM-5zeolite;
a shell comprising a mesoporous fibrous silica comprising KCC-1 and heteroatoms comprising aluminum, the shell in direct contact with at least a majority of an outer surface of the core; and
wherein:
the catalyst system has a Si/Al molar ratio of greater than 5 to equal or less than 20, and
at least a portion of the shell has a thickness of from 90 nanometers (nm) to 180 nm.
