    摘要: The present invention provides a hybrid catalyst which is prepared by mixing a methanol synthesis catalyst with SAPO-type zeolite as a methanol conversion catalyst, and a process for the preparation of hydrocarbons from carbon dioxide by using the hybrid catalyst. The hybrid catalyst of the invention can be used for preparing hydrocarbons having a carbon number of more than 2 from carbon dioxide under a relatively on the hydrocarbons produced. Therefore, the hybrid catalyst may be used for preparing various high-valued hydrocarbons from an ubiquitous carbon source of carbon dioxide.

    摘要: The invention is directed to a method of stabilizing metalloaluminophosphate molecular sieves and catalysts derived therefrom. In particular, the invention is directed to a method of treating such molecular sieves with one or more nitrogen containing compounds selected from the group consisting of amines, monocyclic heterocyclic compounds, organonitrile compounds and mixtures thereof to chemisorbed and/or physisorbed the compound onto the molecular sieve. The compounds may be easily desorbed before or during use and after storage. The invention is also directed to formulating the molecular sieve into a catalyst useful in a process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, preferably an oxygenate containing feedstock.
