摘要
本文用氧吸附法和程序升温脱附（ＴＰＤ）法分别考察低Ｎｉ／改性Ａｌ２Ｏ３催化剂的分散度，环已烷和苯的吸附脱附性能。结果表明：该催化剂分散性好，表面至少存在两种吸附中心。苯、环已烷在该催化剂的表面上属于一级可逆吸附脱附过程，催化剂表面能量分布不均匀。
This paper studied the absorption and desorption characteristics of cyclohexane and benzene on the low Ni/Al 2O 3 catalyst by the method of TPD, and the dispersion-degree of Ni on the low Ni/Al 2O 3 Catalyst was determined, The result indicated that there were at least two kinds of adsorption centre on the surface of the catalyst, The dispersion degree of Ni was improved, Benzene and cyclohexane were the first order reversible adsorption and desorption process. The energetic distribution of the catalyst is unequal.
