Abstract
A zeolite-containing fixed bed catalyst is formed by pre-shaping a mixture of a reactive aluminum-containing component and a matrix component into pre-shaped particles, and contacting the pre-shaped particles with a reactive liquid containing a silicate for a sufficient time and temperature to form an in-situ zeolite within the pre-shaped particles. The contacting of the pre-shaped particles and the liquid is achieved such that there is relative movement between the pre-shaped particles and the liquid.
Claims20
A fixed bed catalyst comprising:
- a pre-shaped particle having been formed from a mixture of a reactive aluminum-containing component and one or more matrix-forming components, wherein the pre-shaped particle is shaped in a form of an extrudate, pellet, or sphere;
- and
- zeolite Y crystallized on the pre-shaped particle, the zeolite Y having been crystallized by contacting the pre-shaped particle with a liquid containing a reactive silicate component for a time and at a temperature sufficient to crystalize the zeolite Y.
