摘要:在化工生产、科学家实验和生命活动中,催化剂都大显身手。例如,硫酸生产中要用五氧化二钒作催化剂。由氮气跟氢气合成氨气,要用以铁为主的多分组催化剂,提高反应速率。在炼油厂,催化剂更是少不了,选用不同的催化剂,就可以得到不同品质的汽油、煤油。化工合成酸性和碱性色可赛思催化剂。车尾气中含有害的一氧化碳和一氧化氮,利用铂等金属作催化剂可以迅速将二者转化为无害的二氧化碳和氮气。本文就铂催化剂的组成、应用、优点、制备方法、使用方法、失活原因以及再生方法作如下论述。

Abstract: In the chemical production, scientists experiment and life activities, catalysts flourish. For example, the production of sulfuric acid as a catalyst in the use of vanadium pentoxide. By the ammonia nitrogen with hydrogen gas, use of iron-based multi-packet catalyst increases the reaction rate. At the refinery, the catalyst is indispensable, use of different catalysts, you can get different quality of gasoline, kerosene. Chemical synthesis of acidic and basic color can be SHINES catalysts. Vehicle exhaust of harmful carbon monoxide and nitric oxide, the use of
a metal such as platinum as a catalyst can be quickly converted to be either harmless carbon dioxide and nitrogen. Enzymes are plants, animals and anisms produce proteins with catalytic ability anisms almost all chemical reactions
carried out in enzyme catalysis, brewing industry, the pharmaceutical industry as a
