The costs and environmental impacts of catalyst manufacture are often neglected during early-stage research because of a lack of accessible, standardized tools to assess them. Here we report the key features of CatCost, a free and public estimation tool for the evaluation of catalyst cost. We demonstrate its functionality with a case study of diverse catalysts (ZSM-5, Pt/TiO₂ and Mo₂C) for the catalytic fast pyrolysis of biomass. We quantified the economic and environmental improvements made by replacing circulating-bed ZSM-5 with more stable, fixed-bed Pt/TiO₂ and Mo₂C catalysts, while revealing the effects of synthesis methods and production scale on catalyst costs. The manufacture of ZSM-5 had a large processing cost contribution that was strongly scale dependent, whereas the costs of the other catalysts were dominated by raw materials at all scales. Furthermore, while ZSM-5 costs the least per kilogram, the more stable catalysts cost half as much per gallon of fuel.

由于缺乏可访问的标准化工具来评估催化剂制造的成本和环境影响，因此在早期研究中经常被忽视。在这里，我们报告了 CatCost 的主要功能，这是一种用于评估催化剂成本的免费和公共估算工具。_{我们通过对用于生物质催化快速热解的多种催化剂（ZSM-5、Pt/TiO 2}和 Mo ₂ C）的案例研究来展示其功能。我们量化了用更稳定的固定床 Pt/TiO ₂和 Mo _{2代替循环床 ZSM-5 所带来的经济和环境改善}C催化剂，同时揭示了合成方法和生产规模对催化剂成本的影响。ZSM-5 的制造具有很大的加工成本贡献，其强烈依赖于规模，而其他催化剂的成本在所有规模下都由原材料主导。此外，虽然 ZSM-5 每公斤的成本最低，但更稳定的催化剂每加仑燃料的成本只有一半。
