Abstract

The invention relates to a preparation method of a molybdenum modified molecular sieve loaded nickel-based methane dry reforming catalyst. The catalyst takes a molecular sieve as a carrier, nickel and molybdenum are respectively loaded on the molecular sieve by a sequential impregnation method, and dispersion of active species and strong interaction with the carrier are realized. The molybdenum-modified molecular sieve supported nickel catalyst is obtained through drying, high-temperature calcination and programmed heating reduction, the catalytic activity can be effectively improved, and carbon deposition in the reaction is effectively eliminated through dynamic conversion of molybdenum oxide and molybdenum carbide on the molecular sieve constructed in the reaction. Finally, the catalytic material with high sintering resistance and carbon deposition resistance is obtained. The catalyst has the advantages of simple preparation process, low cost and high catalytic efficiency.

Description

technical field

[0001] The invention relates to a nickel-based catalyst supported by a molybdenum-modified molecular sieve, a preparation method and an application, and belongs to the technical fields of nano-catalyst preparation technology and environmental protection. The catalyst can effectively solve the problem of sintering of reactive components under high temperature conditions and carbon deposition in the reaction. Background technique

[0002] With the rapid development of society, the combustion and consumption of fossil energy has brought about increasingly serious environmental problems, among which carbon dioxide and methane gas are one of the main culprits causing the greenhouse effect. Methane dry reforming reaction can efficiently utilize CH 4 and CO 2 Conversion to syngas CO and H 2 , on the one hand, this reaction can reduce the use of fossil fuels to alleviate the greenhouse effect, on the other hand, its product H 2 Syngas with a / CO of 1 is the main ...
