载体的选择及其物性的要求,载体在催化剂在方面载的作用,选择适宜的载体是确保催化性能的关键,具有的比表面积能使活性组分得以较高的分散,载体的主要物性要求载体的孔结构能提供尽可能大的反应接触面积,提高活性组分的分散度。小孔径,有利于催化剂的初活性和容纳更多的金属,用于载体在催化剂在方面裂解汽油段加氢的新型贵金属催化剂的制备。
Carrier selection and physical properties of the carrier in the catalyst contained in the role of the appropriate choice of carrier is to ensure the catalytic performance of the key to have the specific surface area of the active components can be higher dispersion of the carrier’s main physical properties require the carrier The pore structure provides as large a reaction contact area as possible and increases the dispersibility of the active ingredient. The small pore size facilitates the initial activity of the catalyst and accommodates more metal for the preparation of a new noble metal catalyst for the support hydrogenation of the catalyst in the cleaved gasoline section.
