METHOD FOR PREPARING NICKLE-BASED CATALYST CARRIED BY MODIFIED DOLOMITE AND APPLICATION THEREOF

摘要

A method for preparing a nickel-based catalyst carried by modified dolomite and an application thereof. The modified dolomite is obtained by means of high-temperature calcination, and the modified dolomite is used as a carrier, while nickle is used as an active component to prepare the nickel-based catalyst carried by modified dolomite. The nickel-based catalyst carried by modified dolomite has good catalytic activity and a stable structure, while air ducts do not easily become blocked due to calcination expansion at high temperatures. The prepared nickel-based catalyst carried by modified dolomite is used during a pyrolysis reaction of tar and macromolecular organic gas that are produced by the pyrolysis of organic solid waste, the catalyst being capable of effectively removing such substances.
