Synthesis of molybdenum sulphide with controllable layer number and application of molybdenum sulphide with controllable layer number in aromatic phenol and ether reactions

Abstract

The invention discloses synthesis of a molybdenum sulphide catalyst with a controllable layer number, and application of the molybdenum sulphide catalyst with the controllable layer number in aromatic phenol and ether reactions. The catalyst takes molybdenum sulphide as a main active component; one or more of the metals, namely, nickel, cobalt, iron, ruthenium, rhodium, palladium, osmium, iridium, platinum and copper, can be added to serve as a second component; the catalyst can be loaded on one or a composite carrier of a carbon material (including AC, VB, CF, Graphene, CT, a mesoporous carbon material and the like), a molecular sieve (including a sliicon-alumininm molecular sieve and a phosphorous-aluminium molecular sieve), an oxide (including gamma-Al2O3, ZrO2, TiO2 and the like), and is used for catalytic hydrogenation reactions of aromatic phenols and ether compounds. The catalyst can catalyze the conversion of the aromatic phenols and the ether compounds into high value-added fine chemicals efficiently under the conditions that the temperature is 150 to 350 DEG C and the initial hydrogen pressure to 2 to 6 MPa. The preparation method for preparing the molybdenum sulphide catalyst is simple and feasible; layer number controllable synthesis of the molybdenum sulphide can be realized; moreover, both a precursor and the catalyst are stable in air; the catalyst has very high stability.

Description

technical field [0001] The invention belongs to the technical field of catalytic conversion of biomass derivatives, in particular to the synthesis of a molybdenum sulfide catalyst with a controllable layer number and its hydrogenation reaction in lignin single / dimerization model compounds such as aromatic phenol and ether small molecule compounds A method for preparing high value-added fine chemicals with an aromatic structure. Background technique [0002] As we all know, since the three technological revolutions, energy has become the lifeblood of the national economy. And the energy on earth is limited. Fossil fuels, represented by oil, are a major source of energy, accounting for three-quarters of the world's energy supply [1] . Fossil fuels are non-renewable energy sources. With their increasing consumption, rising prices, and the improvement of environmental protection regulations, energy shortages, energy conservation and emission reduction have become important fa...
