A method for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms, including bringing a raw material which contains a light hydrocarbon having 2 to 7 carbon atoms as a main component into contact with a catalyst composition for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms. The catalyst composition for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms is coated with an amorphous silicon oxide compound and contains a crystalline aluminosilicate, and the silicon oxide compound is a silicon oxide compound derived from a compound represented by XSi(OR), where X represents a hydrogen atom or an alkyl group, R represents an alkyl group, and n represents an integer of 0 to 4.

Method for producing monocyclic aromatic hydrocarbon having 6-8 carbon atoms

To provide a hydrocarbon reforming/trapping material which is capable of adsorbing and reforming a hydrocarbon. A hydrocarbon reforming/trapping material of the present invention has an SiO/Al2Oratio of from 7 to 12, and contains an Fe(II)-substituted beta zeolite which is ion-exchanged by Fe(II) ions. The amount of supported Fe(II) is preferably 0.001-0.5 mmol/g with respect to the Fe(II)-substituted beta zeolite. This Fe(II)-substituted beta zeolite is suitably produced by dispersing and mixing a beta zeolite having an SiO/AlOratio of from 7 to 12 in an aqueous solution of a water-soluble compound of divalent iron, and mixing and stirring the solution, so that Fe(II) ions are supported on the beta zeolite.

Hydrocarbon reforming/trapping material and method for removing hydrocarbon

The purpose of/problem to be addressed by the present invention is to provide: an Fe(II)-substituted beta-type zeolite useful for the catalytic removal of a variety of gases; and a production method therefor. The SiO/AlOratio in this Fe(II)-substituted beta-type zeolite is equal to or more than 7 but less than 10. This Fe(II)-substituted beta-type zeolite is obtained by being subjected to ionic exchange with Fe(II) ions. It is preferable that the Fe(II) loading amount be in the range of 0.001-0.4 mmol/g of the Fe(II)-substituted beta-type zeolite. It is preferable that the Fe(II)-substituted beta-type zeolite be produced using a method in which a beta-type zeolite having an SiO/AlOratio of equal to or more than 7 but less than 10 is dispersed in an Fe(II) water-soluble-compound aqueous solution, and then mixed and agitated to cause the beta-type zeolite to carry Fe(II) ions.

The purpose of/problem addressed by the present invention is to provide: an Fe(II)-substituted MEL-type zeolite useful for the catalytic removal of a variety of gases; and a production method therefor. The SiO/AlOratio in this Fe(II)-substituted MEL-type zeolite is in the range of 10-30 inclusive. This Fe(II)-substituted MEL-type zeolite is obtained by being subjected to ionic exchange with Fe(II) ions. It is preferable that the Fe(II) loading amount be in the range of 0.001-0.4 mmol/g of the Fe(II)-substituted MEL-type zeolite. It is preferable that the Fe(II)-substituted MEL-type zeolite be produced using a method in which an MEL-type zeolite having an SiO/AlOratio in the range of 10-30 inclusive is dispersed in an Fe(II) water-soluble-compound aqueous solution, and then mixed and agitated to cause the MEL-type zeolite to carry Fe(II) ions.

To provide an Fe(II)-substituted beta type zeolite which has been ion-exchanged with Fe(II) ions and can effectively adsorb and remove nitrogen monoxide or hydrocarbon contained in gas to be cleaned, even if oxygen is present in the gas at a high concentration or the temperature of the gas is low. In the Fe(II)-substituted beta type zeolite, a ratio of SiO/AlOis preferably 10 to 18, a BET specific surface area is preferably 400 m/g to 700 m/g, a micropore specific surface area is preferably 290 m/g to 500 m/g, and a micropore volume is preferably 0.15 cm/g to 0.25 cm/g. The amount of Fe(II) supported is preferably 0.01% by mass to 6.5% by mass based on the Fe(II)-substituted beta type zeolite.

After sand of one layer is loaded into a sand layer elevator (20), a shading mask (38) is positioned above the sand, and a diffused laser beam is irradiated from a diffused laser irradiating source (16). Thereby, a predetermined range of sand under the shading mask (38) is exposed and this exposed portion is cured. This operation is repeated for a predetermined number of sand layers and cured portions are piled up to directly form a 3-D sand mould. Particularly, a diffused laser beam is used to cure a wide range of sand at a time, thereby making sand mould mass-production possible.
