C0₂ TREATMENTS USING ENZYMATIC PARTICLES SIZED ACCORDING TO REACTIVE LIQUID FILM THICKNESS FOR ENHANCED CATALYSIS

摘要

Techniques for absorbing or desorbing CO₂ include sizing enzymatic particles in accordance with the reactive liquid film thickness (δ_rf) of the reaction medium to increase enzymatic catalysis of the CO₂hydration or dehydration reaction. Absorption may include contacting a CO₂ containing gas with an aqueous absorption mixture and determining (δ_rf)of the C2O₂ hydration reaction, wherein (δ_rf) = (δ_ι)/ Ha where Ha² = (k₁.D_co2/(k_L)², Ha 2 and k₁ = k₂C_ab, k₂ being the CO₂ hydration kinetic constant in the mixture and C_ab being the concentration of the absorption compound. The mixture may be under conditions that provide(δ_rf) that is smaller than the liquid film thickness (δ_ι) through which mass transfer of the CO₂occurs. The size ratio of the enzymatic particles and(δ_rf) enhances enzymatic catalysis. Various implementations including processes, systems, formulations and kits are provided.
