MCM-49 zeolite catalyst yɛ microporous aluminosilicate molecular sieve a ɛwɔ afã abiɛsa a ɛwɔ MWW topology, a ɛyɛ saa nhyehyɛe yi tẽẽ bere a wɔayɛ no. Sɛ́ acid catalyst anaa catalyst fã no, MCM-49 wɔ mfaso kɛse wɔ solid acid catalysis mfuw te sɛ alkylation ne isomerization.
MWW soronko abiɛsa-afã nhyehyɛe nhyehyɛe nhyehyɛe a MCM-49 zeolite ma no soronko nsusuwii-paw catalytic su ahorow. Na aluminium atom a ɛwɔ framework no mu no betumi ama Brønsted acid mmeae aba, na ɛde solid-state acidity a emu yɛ den aba.
