Amorphous alloy catalysts are used to catalyze the liquid hydrogenation of furfural to furfuryl alcohol

Furfuryl alcohol, chemically known as furanmethanol and 2-hydroxymethylfuran, is an important organic raw material. Furfuryl alcohol is widely used in industry, can be used as a smell in the production of calcium fructose and many other organic products, but also can be used as raw materials to prepare various properties of furan resin, furfuran alcohol-urea-urea-formaldehyde resin and phenolic resin, as well as plasticizers with excellent cold resistance. In addition, in recent years, it has also been widely used in synthetic fiber, rubber, pesticide and casting industries. Furfuryl alcohol is an important derivative of furfural and is the main product of furfural deep processing, and furfuryl alcohol mainly comes from furfural catalytic hydrogenation. At present, there are two methods for the catalytic hydrogenation of furfural to furfuryl alcohol in industry: liquid phase hydrogenation and gas phase hydrogenation. Most of the catalysts for the production of furfuryl alcohol in China are Cu-Cr catalysts imported from abroad, which contain carcinogens Cr, so in recent years, the main research hotspot is no Cr catalysts that do not pollute the environment or less pollution.
Mo modification was added to an amorphous alloy catalyst to catalyze the reaction of furfural by liquid phase hydrogenation to furfuryl alcohol. A series of characterization methods such as differential scanning calorimetry (DSC), specific surface test (BET), programmed temperature reduction (TPR) and programmed temperature desorption (TPD) were used to study the thermal stability and surface properties of the catalyst and explore the active center of the catalyst. The results show that the amorphous alloy catalyst shows high catalytic activity and selectivity for furfuryl alcohol, and when the content of added Mo in the catalyst is 1.25%~2.5%, the conversion rate of furfural and furfuryl alcohol selectivity reach 100%.

Reni nickel catalyst science knowledge(1)

Physical and chemical properties: Reni nickel catalyst before activation is silver-gray amorphous powder (nickel-aluminum alloy powder), with a moderate degree of flammability, partial activation in the presence of water and the production of hydrogen easy agglomeration, long-term exposure to air is easy to weather. Nickel-aluminum alloy powder is activated into gray-black particles, accompanied by active hydrogen, extremely unstable, oxidative combustion in the air, must be immersed in water or ethanol for preservation. It was first used by American engineer Murray Rainey as a catalyst in the hydrogenation of vegetable oils. The preparation process is to treat nickel-aluminum alloy with concentrated sodium hydroxide solution, in this process, most of the aluminum will react with sodium hydroxide and dissolve, leaving a lot of micropores of different sizes. In this way, the surface of Raininickel is a fine gray powder, but from a microscopic point of view, each tiny particle in the powder is a three-dimensional porous structure, this porous structure greatly increases its surface area, and the large surface area brings high catalytic activity, which makes Raininickel widely used as a heterogeneous catalyst in organic synthesis and industrial hydrogenation reactions. Since "Rainey" is a registered trademark of Grace Chemicals, strictly speaking, only products manufactured by the company's Davidson Chemical Division can be called "Lanny Nickel". The term "metal backbone catalyst" or "sponge-metal catalyst" is used to refer to catalysts with a microporous structure and physical and chemical properties similar to Raney nickel.
