Catalyst LCA — Zeolite Beta Synthesis
Life Cycle Assessment · Zeolite Beta Catalyst
Catalyst — LCA Calculator
Functional unit: 1 kg H-form zeolite Beta. Enter your own process quantities (kg or kWh or MJ per kg product) for the selected synthesis route. Factors are sourced from GREET 2025 where available; specialty synthesis reagents not modeled in GREET (organic template, metal-alkoxide/aluminate precursors) use published cradle-to-gate factors instead — each row is tagged with its source.

Data sources: Electricity, natural gas (upstream), sodium hydroxide, sodium silicate, aluminum sulfate, ammonium nitrate/chloride/sulfate — Argonne GREET 2025 Rev.1 / GREET2 / GREET Building module (cradle-to-gate). Natural gas combustion — EPA/IPCC default (HHV basis), added on top of GREET's upstream-only fuel factor. Colloidal silica, TEOS, aluminum isopropoxide, sodium aluminate, TEAOH — published cradle-to-gate factors (ecoinvent-3.7-derived) from the source zeolite-Beta synthesis LCA manuscript, since GREET does not model these specialty reagents.
Simplifications: Wash-water and ion-exchange-water volumes are excluded (typically a minor contributor). Zeolite Beta seed crystals (SOF route) are not modeled — the original study computes this via a separate nested synthesis calculation. This is a simplified, user-customizable estimate, not a full reproduction of the source study's uncertainty/sensitivity analysis.
