    摘要： Provided is a method for producing an MTW-type zeolite. The reaction mixture contains a silica source, an alumina source, an alkali source, and water is reacted with a seed crystal of a zeolite to produce an MTW-type zeolite. The reaction mixture has a composition, which makes a synthesized zeolite contain an MFI-type zeolite when the zeolite is synthesized solely from the reaction mixture, is used. As the seed crystal, a beta-type zeolite which has a ratio of SiO2/Al2O3 of 8 to 50 and does not contain a structure direction agent is used. The seed crystal is added to the reaction mixture, in a proportion of 0.1% by mass to 20% by mass based on a silica component in the reaction mixture. The reaction mixture to which the seed crystal has been added is heated at 100° C. to 200° C. in a sealed state.

    摘要： Molecular sieves and the use of such materials as hydrocarbon traps, particularly for reducing the emissions associated with the combustion of hydrocarbon fuels are described. Specifically, the use of molecular sieves such as zeolites as adsorbents for hydrocarbon gases, especially exhaust gases such as are formed during the combustion of hydrocarbons, and more particularly to the adsorption of hydrocarbon gases formed during the cold start operation of an internal combustion engine is described. In one embodiment, a method of treating exhaust gas that comprises a hydrocarbon combustion product is provided, the method comprising contacting the exhaust gas with a CON topology molecular sieve for a time period effective to facilitate adsorption of the hydrocarbon combustion product by the molecular sieve; passing a purge gas through the molecular sieve to remove adsorbed hydrocarbon combustion product; and contacting the purge gas containing the removed hydrocarbon combustion product with a hydrocarbon conversion catalyst.
