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.
Claims7
A fixed bed catalyst composition comprising an extrudate, wherein
- the extrudate has a diameter of from about 0.05 to 0.5 inch and a length of from about 0.05 to 1 inch, and comprises:
- a macroporous alumina-containing matrix;
- and
- a metal having a hydrogenation function;
- wherein the matrix comprises macropores having zeolite Y crystallized on walls of the macropores.
