摘要：

The use of Spanish natural clays as additional silica sources to synthesize 13X zeolite from kaolin with adequate specifications to be used as a detergent builder has been investigated. A bentonite has been selected as the most appropriate, and the best calcination conditions for its use have been determined. The process variables for the different synthesis steps have been optimized and compared with those obtained using other additional silica sources. The scale-up to a pilot plant and the recovery of mother liquors has been verified.
