They should show a preferred selectivity for propylene glycol and optionally ethylene glycol.
- the object is achieved by a hydrogenation catalyst containing 1 to 50 wt .-%, based on the total catalyst, of nickel on a support of carbon, wherein the hydrogenation catalyst does not contain rhenium.
- hydrogenation catalysts are suitable for the hydrogenation of sorbitol to glycols which contain nickel but not rhenium as active metal on a carbon support.
- the catalysts are accessible in a simple manner, since it only has to be impregnated with an active metal. In addition, they are significantly less expensive than known catalysts because they dispense with the use of expensive rhenium and use inexpensive carbon support.
- the catalyst according to the invention contains no rhenium. This means that no technically effective amounts of rhenium are contained in the catalyst and thus rhenium has no significance as an active metal.
- catalysts which contain only nickel as the active metal.
- further active metals such as molybdenum, vanadium or tin and mixtures thereof in addition to nickel.
- the catalyst of the invention contains nickel in an amount of 1 to 50 wt .-%, preferably 5 to 40 wt .-%, in particular 10 to 30 wt .-%, based on the total catalyst.
- the proportion of other metals is 0 to 25 wt .-%, preferably 0 to 15 wt .-%, in particular 0 to 5 wt .-%. If such metals are present, their minimum amount is preferably 0.5 wt .-%.
- no further active metals are particularly preferably present on the catalyst support. More preferably, only nickel is present as the active metal on the catalyst support. In particular, the carbon support is impregnated only with nickel as the metal.
- Any suitable carbon support can be used according to the invention.
- coconut shells, olive pits or peat coal can be used as carbon carriers. It is also possible to use synthetic carbon carriers. Coconut shell carbon is particularly preferably used as support.
- the carbon support can be used untreated or pretreated to prepare the catalyst.
- a pretreatment of the carbon is possible for example by heat, steam, acids or chemical pretreatment.
- a steam pretreatment of the coconut shell carbon is carried out with steam.
- the carrier may have any suitable particle size.
- the support preferably has an average particle diameter in the range from 0.5 to 5 mm, particularly preferably 0.75 to 3.5 mm, in particular 1 to 2 mm.
- the hydrogenation catalyst used according to the invention can be prepared by any suitable method. Usually, it is prepared by impregnating the carrier with a nickel salt solution, then drying and then reducing. The reduction is preferably carried out at a temperature above 300 ° C, more preferably in the range of about 300 ° C to 700 ° C, in particular in the range of 400 to 600 ° C, especially in the range of 400 to 500 ° C. For example, the reduction treatment may be carried out at about 500 ° C.
- the invention also relates to a catalyst which can be prepared by the above process.
- the invention also relates to a process for preparing the above catalyst by impregnating the support of carbon with a nickel salt solution, then drying the impregnated support and subsequently reducing the dried support at a temperature above 300 ° C.
- the abovementioned reduction temperatures are preferably used.
- Impregnation may be by any suitable impregnation method. Preferably, a vacuum impregnation is carried out. It can be assumed that any suitable nickel salts. Nickel nitrate is preferably used as the aqueous solution.
- the drying is preferably carried out at a temperature in the range of 50 to 150 ° C at normal pressure or preferably at reduced pressure. Most preferably, it is dried under vacuum or reduced pressure.
- the reduction is preferably carried out in the presence of a gas containing free hydrogen, in particular in a hydrogen atmosphere.
- the reduction may be followed by stabilization of the nickel-containing catalyst, for example in air at room temperature, in order to arrive at a storable stable nickel catalyst.
- Typical hydrogenation conditions in the hydrogenation of sorbitol are a temperature in the range of 150 to 350 ° C, preferably 200 to 300 ° C, in particular about 250 ° C, a hydrogen pressure in the range of 50 to 300 bar, in particular of about 150 bar, a Sorbitol concentration of 10 to 40 wt .-% in water, especially about 20 wt .-% in water, a starting pH in the range of 12 to 13, for example, adjusted by the addition of KOH.
- sorbitol is usually carried out at a temperature of 250 ° C, a hydrogen pressure of 150 bar, a pH of 12 to 13 to a 20 wt .-% - aqueous sorbitol solution.
- the degree of reduction of the sorbitol is preferably in the range of 50 to 99%.
- the strength of the catalysts is determined.
- the carbon carriers in particular the coconut shell carbon carriers, there is no reduction of the starch by the hydrogenation.
- the catalysts of the invention are thus preferably used for the hydrogenation of sorbitol to glycols, in particular propylene glycol and ethylene glycol, with small amounts of glycerol, or for the hydrogenation of glucose to sorbitol.
- the invention thus also relates to a process for the preparation of glycols by hydrogenation of sorbitol, in which the hydrogenation is carried out on a catalyst as described above.
