Procedure for producing an aluminium-boron-silicate catalyst with the configuration 0.8-1.2 M2/n 0 : Al203 : 0.005-0.1 B203 : 10150 Si02 : x H20. In the procedure, a reaction mixture is heated which contains a cation with organic nitrogen, an alkali metal oxide or a mixture of such, aluminium oxide, boron oxide and silicon dioxide and water, in a closed reaction vessel first at a higher temperature and thereafter at a lower temperature for producing an aluminium-boron-silicate catalyst. The cation containing organic nitrogen has been derived from pyrrolidine or tetraethyl, tetrapropyl or tetrabutyl ammonium chloride or their mixture. |
