Abstract
A calcium silicate based nickel catalyst and a preparation method and application thereof are provided. The method includes: leaching a silicon based solid waste with an alkali agent to obtain a silicate leaching solution; adding the silicate leaching solution and a nitrate solution corresponding to a lanthanum metal dropwise to a calcium hydroxide suspension for a first precipitation reaction, and subjecting a precipitate produced by the reaction to filtration, drying and calcination to obtain a modified calcium silicate support; and dispersing the modified calcium silicate support in an anhydrous alcohol solvent to obtain a mixed suspension, adding an alcohol solution of a nickel salt dropwise to the mixed suspension for a second precipitation reaction, conducting heating and stirring until alcohols in the anhydrous alcohol solvent and the alcohol solution of a nickel salt are volatilized, and conducting drying and calcination to obtain the modified calcium silicate based nickel catalyst.
