The invention further relates to the production of the catalyst according to the invention and to a process for ammonia synthesis using the catalyst according to the invention.

Abstract: The invention relates to a method for producing iron-containing shaped catalyst bodies by means of 3D printing technology and to iron-containing shaped catalyst bodies that are obtainable by this method and to their use as catalysts in the ammonia synthesis or the Fischer-Tropsch reaction.

Abstract: Disclosed is a process whereby completed catalysts can be produced from the iron oxides, and these catalysts can be activated and employed directly after activation for ammonia synthesis from synthesis gas, comprising for example a mixture of nitrogen and hydrogen. A process is also disclosed to produce pre-reduced catalyst precursors, which are first reduced under controlled conditions and subsequently passivated in an oxidizing atmosphere, before they are used in ammonia synthesis as catalysts. These pre-reduced catalysts can be activated significantly more quickly and under milder conditions than the iron oxides.

Abstract: The present invention provides a process for preparing 1,2-pentanediol by reacting furfuryl alcohol with hydrogen in the presence of a catalyst system. The catalyst system contains platinum oxide or contains ruthenium supported on aluminum oxide or activated carbon. The invention also relates to the respective catalysts and processes for producing the catalyst system.

Abstract: A process for applying a lubricant to a plurality of yarn packages directly to a dye bath in a package dyeing machine during the dyeing process. The process includes placing a plurality of yarn packages into a package dyeing machine. The plurality of yarn packages are then dyed in the package dyeing machine and the dye bath is cooled. A lubricant is then directly applied to the dye bath and the plurality of yarn packages in the package dyeing machine. In the preferred embodiment, the lubricant is a wax emulsion based on paraffin wax with a melting point of between about 138.degree. F. to 143.degree. F.

Abstract: A process of treating sheet materials with an aqueous treating composition is disclosed in which surfactants are incorporated in the composition to permit it to be foamed with gas to provide a foam which is stable in the form of a thin layer long enough to be handled, but which will collapse completely when heated. This is preferably done by employing a mixture of water soluble surfactant to stabilize the foam and water insoluble defoamer to break the foam when heat is applied. This foam is applied to a surface of the sheet material to provide stable foam thereon, and heat is employed to simultaneously cause the foam to collapse and dry the composition.

Abstract: Polyethylene terephthalate fiber-containing fabric is flameproofed by application of an aqueous suspension of finely divided particles consisting essentially of octagonal hexabromide formed by the incomplete bromination of cis, trans, trans cyclododecatriene to provide a mixture having a melting point in the range of 177.degree.-191.degree. C. determined by differential scanning colorimetry using a heating rate of 10.degree. C. per minute. The treated fabric is dried and then heated with the octagonal hexabromide particles thereon to a temperature above the melting point of the mixture, but not in excess of about 200.degree. C. for a period long enough to achieve adequate penetration (30 seconds), to cause the hexabromide particles to diffuse into the fibers of the fabric to maximize fire resistance and obtain proper fixation of the particles to the fabric in a manner providing durability to laundering with minimum damage to the fabric.

Abstract: A textile treating composition adapted to provide a relatively permanent antistatic and dirt repellent finish and consisting essentially of an aqueous dispersion of:1. about 10% to about 20% of an antistatic agent comprising a compound of the formula ##STR1## in which R is an alkyl radical having 14 to 20 carbon atoms, R.sub.1 and R.sub.2 are, each independently, alkyl, hydroxy alkyl, alkyl substituted by carboxylic and/or sulphonic acid groups, aminoalkoxyalkyl or aminoalkyl wherein the amino group is unsubstituted or substituted by hydroxyalkyl, cyanoalkylaminoalkyl or by the group R--CO-- or --R--CO--NH-alkoxyalkyl wherein R is alkyl having 14 to 20 carbon atoms, or one of R.sub.1 and R.sub.2 is hydrogen;2. about 3% to about 35% of an aqueous dispersion of hard particles having a weight average particle diameter of less than about 2 microns;3. about 1% to about 6% of a fluorine-free inorganic or organic monobasic or polybasic acid;4. 0% to about 5% of an antimicrobic agent; and5.
