| 1. A zeolite which has a framework density of from 10 T/nm3 to 16 T/nm3 and a carbon content of from 1% by weight to 6% by weight and satisfies the following (1) or (2):
(1) the zeolite is an aluminophosphate which has a nitrogen content of from 0.5% by weight to 12% by weight and in which the
aluminum may be partly replaced by Me;
(2) the zeolite is a silicoaluminophosphate in which the aluminum may be partly replaced by Me and which, when burned to a
carbon content lower than 0.3% by weight, retains the framework structure possessed by the silicoaluminophosphate before the
burning:
(provided that Me in (1) and (2) above is at least one element selected from the elements in Groups 2A, 7A, 8, 1B, and 2B
of the periodic table).
