Abstract

The invention discloses a catalyst for preparing 2-methyl furan through furfural gas phase hydrogenation and a preparation method thereof. The catalyst contains the following components in percentage by mass: 52-56% of CuO, 40-42% of SiO2 and 3.0-6.0% of CeO2. The preparation method of the catalyst comprises the following steps: (1) respectively preparing a soluble salt solution of copper, a soluble salt solution of cerium and a silica sol, and mixing to obtain a mixed solution; (2) adding an alkaline precipitant into the mixed solution to perform precipitation, and heating to obtain a precipitate; and (3) drying and roasting the precipitate sequentially to obtain the catalyst. Compared with the prior art, the catalyst has the following advantages: (1) the catalyst has single components, namely only has three components, and the raw materials are cheap and readily available; (2) the catalyst, which does not contain extremely poisonous cancerogenic substance Cr, does not have harm to environment and human body; (3) the catalyst has relatively predominant low-temperature activity; and (4) the catalyst has relatively high activity and selectivity.

Description

technical field

[0001] The invention relates to a catalyst for preparing 2-methylfuran by gas-phase hydrogenation of furfural and a preparation method thereof, belonging to the field of catalyst preparation and application. Background technique

[0002] 2-Methylfuran is an important organic chemical intermediate, which is widely used in medicine, pesticide and fine chemical industry. 2-Methylfuran is used to prepare vitamin B1, chloroquine phosphate and primaquine phosphate and other drugs, synthetic pyrethroid pesticides and flavors and fragrances, and is also a good solvent. At present, 2-methylfuran is considered as an important fuel additive with a high octane number (131), which can be used as an oil additive to improve the anti-knock performance of gasoline, and has a high energy density, which is better than fuel ethanol. better.

[0003] The industrial production of 2-methylfuran is carried out by gas-phase catalytic hydrogenation of furfural, mainly using CuCr sys...
