1, Mo2C/ SAPO -11 catalyst was prepared by temperature programming reduction method using n-hexane as the source of carburization.

2, Latest advances in synthesis of silicoaluminophosphate ( SAPO )molecular sieves and their application in industrial catalysis were reviewed.

3, Ms. Kvarnstrom said SAPO saw no reason to raise its terror alert level, which has been at "elevated" since October.

4, In this paper, the latest advances in the application of silicoaluminophosphate ( SAPO ) molecular sieves to isomeric catalysis are reviewed.

5, It is an important and urgent problem to find some good ways to improve the stability of SAPO molecular sieves.

6, One story says that soap got its name from Mount Sapo, a place where ancient Romans used to sacrifice animals to their gods.

7, Several zeolite catalysts were selected to convert 1 hexene to 2,3 dimethyl 2 butene (DMB 2) in this work. ZSM 35 and SAPO 11 zeolite are suitable skeletal isomerization catalysts.

8, The invention relates to a modification method of a SAPO molecular sieve, mainly aiming at solving the problem of poor performance of the SAPO molecular sieve in the prior art.
