    • A method of supporting a hydrocarbon synthesis catalyst material comprising a catalytically active metal and a carrier material on a substrate comprising the steps of: (a) applying the catalyst material to the substrate; and (b) heating the catalyst material to form a catalyst material layer fixed to the substrate, characterised in that - the catalyst carrier is a porous inorganic refractory oxide or precursor therefor; - the catalyst material applied in step (a) comprises 60 to 90 weight% solvent calculated on the total weight of the catalyst material layer; - when the catalyst material is subjected to the heating step (b) it comprises at most 10 weight% of solvent, calculated on the total weight of the catalyst material layer; - in heating step (b) the catalyst material is heated to a temperature in the range between 250°C and 800°C; - cracks having sub-millimetre widths are uniformly formed in the layer; - after step (b) the catalyst material layer has a thickness of 5-200 microns. The control of cracking of the catalyst material on the substrate, especially the presence of cracks at regular distances such that there is no continuous catalyst layer on the substrate surface, reduces any stress build-up.

    • A spray dried particulate catalyst comprising a catalytically active component, a carrier and optionally a catalyst promoter, is described. The catalyst has a decrease in average particle diameter following the Shear Test as described herein of 25% or less. The fraction of catalyst particles being less than 10 µm in size, can also be less than 20%. The present invention also provides a method of manufacturing a particulate catalyst material comprising preparing an aqueous slurry, spray drying the aqueous slurry using a spray drier with an inlet temperature of less than 300 °C, and calcining the particulate obtained. The invention has found that catalyst strength may be improved by careful manipulation of the spray drying conditions. In particular, it has been found that a catalyst that is spray dried at a relatively low gas inlet temperature, preferably in the range of 200 °C to 250 °C, shows advantageous attrition characteristics (in terms of attrition resistance) compared to catalysts prepared by spray drying at higher temperatures.
    • 描述了包含催化活性组分,载体和任选的催化剂促进剂的喷雾干燥的颗粒催化剂。 如本文所述的剪切试验后,催化剂的平均粒径降低了25%以下。 催化剂颗粒尺寸小于10μm的部分也可以小于20%。 本发明还提供一种制备颗粒状催化剂材料的方法,包括制备含水浆料,使用入口温度低于300℃的喷雾干燥器喷雾干燥含水浆料,并煅烧所获得的颗粒。 本发明已经发现,通过仔细操作喷雾干燥条件可以提高催化剂强度。 特别地,已经发现,在相对低的气体入口温度,优选在200℃至250℃的范围内喷雾干燥的催化剂与制备的催化剂相比,显示出有利的磨耗特性(耐磨性) 通过在较高温度下喷雾干燥。
