Preparation method of 2-methyl furan

The invention discloses a preparation method of 2-methyl furan, comprising the following steps of: allowing gaseous furfural to contact with hydrogen in a hydrogenation reactor to carry out hydrogenation reaction in the presence of a hydrogenation catalyst under the condition of selective hydrogenation reaction, condensing a reaction product and separating an organic phase from a water phase, and sending the organic phase into a rectifying tower for rectification to obtain 2-methyl furan, wherein at least parts of heat discharged during the hydrogenation reaction process through heat exchange is taken as the heat source of the column bottom of the rectifying tower. According to the method, parts of heat discharged from the hydrogenation reactor is used to provide heat source for a reboiler of the rectifying tower, and preferably parts of heat discharged from the hydrogenation reactor is also used as the heat source for heating and vaporization of the liquid phase furfural raw material and for heating of gaseo
