Catalysts for biomass-to-liquid applications via Fischer–Tropsch synthesis need to be robust in terms of synthesis gas composition and should provide an attractive product spectrum to be implemented in the subsequent value chain. This chapter focuses on strategies to design catalysts, with a focus on current developments for active and support materials, as well as structuring and formulation. The following are discussed in particular: the ability of materials to cope with a high oxygen load and poisoning impurities in the synthesis gas; the ability to withstand deactivation processes; approaches to tailoring the product spectrum. Therefore, the impact of the structure and geometry of the catalysts is elaborated on, as well as promising combinations of active and supporting compounds. Hence, the chapter provides a link between material design, catalyst geometry and the reactor scale, while emphasising the Fischer–Tropsch catalyst.
