    摘要: THE INVENTION RELATES TO SILICEOUS MATERIALS, PARTICULARLY ZEOLITE-BASE CATALYSTS, WHICH EMPLOY ACID-TREATED BOEHMITE ALUMINA AS A BINDER. THE ACID TREATMENT CONSISTS OF TREATMENT OF THE BOEHMITE WITH AT LEAST 0.5 EQUIVALENT OF ACID PER MOLE OF BOEHMITE. THE ACID EMPLOYED IN THE TREATMENT IS A MINERAL ACID HAVING A MONOVALENT ANION OR A SALT THEREOF, E.G., NITRIC ACID, HYDROCHLORIC ACID OR THEIR SALTS. THE CATALYSTS FIND UTILITY IN PROCESSES SUCH AS CRACKING, HYDROCRACKING, HYDROTREATING, ISOMERIZATION, ETC. THE BINDER COMPOSITION COMPRISING THE ACID-TREATED BOEHMITE MAY ALSO BE USED FOR BINDING A VARIETY OF SILICEOUS COMPOSITIONS SUCH AS AMORPHOUS COMBINATIONS OF SILICA AND ALUMINA, ACTIVATED CLAYS, SILICA GEL, ETC.
