Randomized trial shows improved kinetics for CO₂ hydrogenation to methanol, indicating better catalyst performance.

The research aims to study the kinetics of CO₂ hydrogenation to methanol using a Cu/ZnO/ZrO₂ catalyst under various conditions.
Experiments conducted under pressures of 30–60 bar and temperatures of 190–250 °C.
H₂ to CO₂ ratios varied from 1 to 6 to assess catalyst performance and stability.
A lumped 6-parameter kinetic model was developed and validated with an extensive dataset of 500 experimental points.
The CZZ catalyst demonstrated improved performance and stability in CO₂ hydrogenation compared to other Cu/ZnO-based catalysts.
The newly developed kinetic model matches or outperforms existing models in sensitivity and extrapolation capabilities.
Kinetic analysis covers a wide range of process conditions relevant for industrial applications.

Niquini et al. (2026) studied this question.
