Abstract
A magnetically recoverable catalyst that includes a core material and a shell material, where the core material is an Fe—Co alloy containing Fe and Co in an equal molar ratio and the shell material is a graphitic carbon. A process for producing the magnetically recoverable catalyst includes mixing of nanoparticles of Fe3O4 with a Co metal-organic-framework material. The magnetically recoverable catalyst of the present disclosure can be used for selective hydrogenation of furfural.
Claims20
A magnetically recoverable catalyst comprising:
- a core material and a shell material;
- wherein the core material is an Fe/Co alloy comprising Fe and Co in an equal molar ratio;
- and
- wherein the shell material is graphitic carbon.
A process for producing a magnetically recoverable catalyst comprising:
- mixing nanoparticles of Fe3O4 with a Co metal-organic-framework material and grinding to form a precursor mixture, wherein the Fe and the Co are present in the precursor mixture in an equal molar ratio;
- and
- heating the precursor mixture to at least 600° C. under an inert gas to form the magnetically recoverable catalyst.
A process for the selective hydrogenation of furfural comprising:
- combining, in a reactor, furfural with a catalyst material comprising an Fe—Co alloy core and a graphitic carbon shell, wherein the Fe and Co are present in equal molar ratios;
- adding an alcohol;
- flushing the reactor at least one time with hydrogen gas;
- pressurizing the reactor to a pressure of at least 10 bar with hydrogen gas;
- and
- heating the reactor to a temperature of at least 140° C. to hydrogenate the furfural in the reactor in the presence of the catalyst material.
