Abstract: A monolithic catalyst, including cobalt, a metal matrix, a molecular sieve membrane, and an additive. The metal matrix is silver, gold, copper, platinum, titanium, molybdenum, iron, tin, or an alloy thereof. The molecular sieve membrane is mesoporous silica SBA-16 which is disposed on the surface of the metal matrix and is a carrier of the active component and the additive. The thickness of the carrier is between 26 and 67 μm. The additive is lanthanum, zirconium, cerium, rhodium, platinum, rhenium, ruthenium, titanium, magnesium, calcium, strontium, or a mixture thereof. A method for preparing the monolithic catalyst is also provided.

Abstract: A catalyst, including a molecular sieve carrier and an active component. The active component includes: iron, manganese, copper, and a basic promoter potassium. The molecular sieve carrier is a cerium salt and/or praseodymium salt modified-aluminosilicate molecular sieve carrier and/or silica-rich molecular sieve carrier. A method for preparing a catalyst for Fischer-Tropsch synthesis, includes: 1) fully dissolving a ferric salt, a manganese salt, a copper salt, and an alkali or a salt containing potassium element in water to yield an aqueous solution, stirring and adding sodium lauryl sulfate to the aqueous solution, and continuing stirring to yield a uniform solution; and impregnating a modified molecular sieve in the uniform solution to yield a mixed solution; and 2) drying and calcining the mixed solution to yield the catalyst.
