To tune the product selectivity by controlling the complicated reaction path is a big challenge in Fischer–Tropsch synthesis. Here, we report an integrated catalytic process for the direct conversion of syngas (CO/H₂) into different types of liquid fuels without subsequent hydrorefining post-treatments of Fischer–Tropsch waxes. Outstanding selectivities for gasoline, jet fuel and diesel fuel as high as 74, 72 and 58% are achieved, respectively, by only using mesoporous Y-type zeolites in combination with cobalt nanoparticles. The types of liquid fuels can be readily tuned by controlling the porosity and acid properties of the zeolites. We further build a new product-distribution model for the bifunctional catalysts, which do not obey the traditional Anderson–Schulz–Flory (ASF) distribution. The present work offers a simple and effective method for the direct synthesis of different types of liquid fuels.

通过控制复杂的反应路径来调节产物的选择性是费托合成中的一大挑战。在这里，我们报告了合成气直接转化（CO / H ₂）转化为不同类型的液体燃料，而无需对费托蜡进行后续的加氢精制后处理。仅通过将中孔Y型沸石与钴纳米颗粒结合使用，可以分别实现高达74％，72％和58％的出色的汽油，喷气燃料和柴油燃料选择性。通过控制沸石的孔隙率和酸性质，可以容易地调节液体燃料的类型。我们进一步为双功能催化剂建立了新的产品分配模型，该模型不遵循传统的安德森-舒尔茨-弗洛里（ASF）分配。本工作为直接合成不同类型的液体燃料提供了一种简单有效的方法。
