铂族金属催化剂在粗汽油重整和控制污染方面仍起着重要作用。由于催化剂在使用过程中发生钝化,人们越发关心这当中所发生的化学反应。阿根廷的M. Parera等人研究了这种催化剂的钝化和再生。他指出,双金属催化剂,如铂-铼-硫/氧化铝,比铂/氧化铝催化剂有更好的选择性,且更稳定,因而目前得到广泛应用。这类催化剂的含铂量仅约 Platinum group metal catalysts still play an important role in crude gasoline reforming and pollution control. Due to passivation of the catalyst during use, people are increasingly concerned about the chemical reactions that take place. M. Parera et al. Of Argentina studied the deactivation and regeneration of this catalyst. He pointed out that bimetallic catalysts, such as platinum-rhenium-sulfur / alumina, are more selective and stabler than platinum / alumina catalysts and are therefore widely used today. The platinum content of such catalysts is only about
