Despite Na\u2010exchanged zeolites are well\u2010known to resist coking in many cracking reactions, they are generally considered catalytically inert for polyethylene cracking due to absent acidity. Here, we show that encapsulated palladium nanoparticles in Na\u2010ZSM\u20105 catalyze efficient polyethylene hydroconversion to C\n                    <jats:sub>5<\/jats:sub>\n                    \u2010C\n                    <jats:sub>9<\/jats:sub>\n                    alkanes with minimal gas yield and negligible coke formation. Mechanistic studies reveal that dihydrogen undergoes heterolytic dissociation at the confined Pd\u2010zeolite interface, concurrently generating PdH hydrides and bridging hydroxyl groups that function as Br\u00f8nsted acid sites.
