Ni/γ-Al_2O_3是化学工业的重要催化剂,它常因反应积炭过多而失去活性.当高温再生处理烧去积炭时,负载金属镍又容易被烧结.因此,探索再生的新工艺成为人们重视的课题.本文根据氧化物和盐类能够在适当的条件下自发单层分散在载体上的原理,设计了两种再生Ni/γ-Al_2O_3催化剂的方法,为改进再生工艺提供了一些科学根据. Ni / γ-Al_2O_3 is an important catalyst in the chemical industry, and it often loses its activity due to too much carbon deposition in the reaction. When high temperature regenerative treatment burns carbon deposition, the loaded nickel metal is easily sintered. Therefore, People pay attention to the subject.In this paper, based on the principle that oxides and salts can be spontaneously monolayer dispersed on the carrier under appropriate conditions, two methods of regenerating Ni / γ-Al 2 O 3 catalyst were designed and some sciences were provided to improve the regeneration process according to.
