METALLOALUMINOPHOSPHATE MOLECULAR SIEVE WITH CUBIC CRYSTAL MORPHOLOGY AND METHANOL TO OLEFIN PROCESS USING THE SIEVE

Title:

METALLOALUMINOPHOSPHATE MOLECULAR SIEVE WITH CUBIC CRYSTAL MORPHOLOGY AND METHANOL TO OLEFIN PROCESS USING THE SIEVE

Document Type and Number:

Japanese Patent JP2002191980

Kind Code:

A

Abstract:

To provide a catalyst for converting methanol into light olefins along with the process itself.

The catalyst is a metalloaluminophosphate molecular sieve having the empirical formula (ELxAlyPz)O2 (wherein SL is a metal such as silicon or magnesium; x, y, and z are the mole fractions of EL, Al, and P respectively). The molecular sieve has predominantly a plate crystal morphology in which the average smallest crystal dimension is at least 0.1 μm and has an aspect ratio of no greater than 5. Use of this catalyst gives a product with a larger amount of ethylene versus propylene.
