Abstract
La presente invención se refiere a un catalizador de ácido fosfórico cristalino sólido con una intensidad total de rayos-X del fosforo de sílice mayor al 30 porciento con respecto a la alfa-alúmina y comprendiendo cristalitos tanto de ortofosfato de sílice como de pirofosfato de sílice con la cristalinidad deseada del catalizador de ácido fosfórico producida mediante la cristalización de una mezcla amorfa de un óxido de ácido de fósforo y un meterial silíce en una proceso de cristalización operado a una temperatura desde 250º hasta 450ºC, y a una concentración de vapor desde 3 hasta 50 moles porciento en base al vapor total en el proceso de cristalización.The present invention relates to a solid crystalline phosphoric acid catalyst with a total silica phosphor X-ray intensity greater than 30 percent relative to alpha-alumina and comprising crystallites of both silica orthophosphate and silica pyrophosphate with the desired crystallinity of the phosphoric acid catalyst produced by crystallizing an amorphous mixture of a phosphoric acid oxide and a silicon meterial in a crystallization process operated at a temperature from 250 ° to 450 ° C, and at a vapor concentration from 3 to 50 % moles based on total vapor in the crystallization process.
