SAPO-18 Applications
Catalytic field:
1. Methanol to olefin (MTO) reaction: the core catalyst or catalytic component for producing ethylene and propylene.
Isomerization, alkylation, and dewaxing processes of hydrocarbons.
Environmental catalysis: reduction of nitrogen oxides (NOx) and oxidative degradation of volatile organic compounds (VOCs).
2. Adsorption and Separation Field:
Capture carbon dioxide from flue gas, natural gas, or biogas.
Separation of light hydrocarbons (such as separation of isomers of C ₂/C ∝ and C ∝/C ₄).
3. Other fields:
Gas storage in energy systems, such as hydrogen and methane.
Ion exchange purification in water treatment.
