    • A process of making a supported catalyst includes steps of preparing a washcoat containing a mixture of hydrolyzed silicon alkoxide and a filler, depositing the washcoat on a surface of a solid support, drying the washcoat deposited on the surface of the solid support to form a coating on the surface of the solid support, and distributing a metal catalyst on the coating. The resulting supported catalyst may be used in a reaction vessel, such as a fixed bed reactor, for effecting a catalytic reaction, such as catalytic hydrogenation of an edible oil. The washcoatings can be formulated to provide a viscous composition that can be applied to form a thick coating on a substrate. The dried washcoatings exhibit excellent stability, cohesive layering strength, and adhesive strength between the coating and a substrate.
    • 制备负载催化剂的方法包括制备含有水解硅烷醇盐和填料的混合物的修补基面涂层的步骤,将固体涂料沉积在固体载体的表面上,干燥沉积在固体载体表面上的修补基面涂料以形成涂层 在固体载体的表面上,并且在涂层上分布金属催化剂。 得到的负载型催化剂可以用于反应容器,如固定床反应器,用于进行催化反应,如食用油的催化氢化。 洗涂剂可以配制成提供粘性组合物,其可以用于在基材上形成厚涂层。 干涂料在涂层和基材之间表现出优异的稳定性,内聚层强度和粘合强度。
