A process for preparing acidic Zeolite Catalysts of medium or small pores with AIPO4 combined with catalytic activity and / or hydrothermal unaestabilidad improvedA process for improving the catalytic activity or laestabilida D hydrothermal Zeolite Catalysts and Cracking process for Hydrocarbon with a catalyst and a Composition of matterIncludes Zeolite Catalysts prepared by or improved processes.The process to improve the catalytic Activ ity of a catalyst of acidic Zeolite pores or small media comprises the steps of treating lazeolita with a Phosphorus Compound to form a ZeWavelet and combine with Phosphorus treated Zeolite treated with AIPO4 confosforo. The option onalmente zeolitatratada with Phosphorus is Calcined.The stage of combining with AIPO4 Zeolite can optionally be followed by steaming The Catalyst combined.The fosforosutiles containing compounds for the treatment of Zeolite include Phosphoric Acid or Ammonium dihydrogen phosphate, mono, fosfitosorgu00e1nicos, and organofosfinas.The Phosphorus containing Compound is preferably an Ammonium acid phosphate.The process to increase estabilidadhidrotu00e9rmica a Zeolite Catalyst comprises First treating a Zeolite with a compound containing Phosphorus and then mix with AIPO4.The catalizadorasu00ed prepared may be used alone or combined with other Catalysts.Can also be used in a p roceso for Cracking hydrocarbons which comprises contacting a feed material to a Hydrocarbon Catalyst prepared as described aboveMind.
