摘要： The invention relates to a catalyst and a method for its manufacture. The catalyst is made of at least two metal foil strips (1, 2), transverse corrugations having been formed in at least one of them. The metal foil strips are formed into a honeycomb (4) containing channels (3). The strips are coated with a support or with supports, and at least one catalytically active agent such as a noble metal is added to the coated strips in order to produce a catalytic surface. In this case the catalytic surface has the physical structure derived from the coating. The honeycomb (4) has at least two catalytic surfaces (5, 6) differing from each other with respect to at least the support or the physical structure.

摘要： The invention relates to a process for the preparation of melamine from urea by feeding molten urea and hot ammonia gas into a reactor having a pressure within the range 50-150 bar and a temperature within the range 360-430 DEG C, whereby a reaction product is obtained which contains a liquid melamine melt and a gas mixture. This gas mixture is separated from the liquid melamine melt, and the liquid melamine melt thus obtained is directed to a vaporizer and is vaporized therein, and the melamine-containing gas obtained from the vaporizer is cooled in a quencher, in which case the melamine crystallizes in a very pure state, the purity being typically at minimum 99.9 %.

摘要： The invention relates to a liquid preservative composition which is suited for the preservation of green forage or the like and which contains as its active ingredient benzoic acid or its derivative. Benzoic acid or its derivative specifically promotes useful microbial activity in green forage. In the present invention their action is enhanced by adding to the composition propionic acid, which dissolves them, or a mixture of the same, together with formic acid and/or acetic acid. These acids also as such promote the said useful microbial activity. Other constituents which improve solubility and conventional agents promoting lactic acid fermentation can also be added to the composition.
