摘要： A manufacturing method of a honeycomb structure includes a forming step of forming a honeycomb formed body by use of a kneaded material containing a cordierite forming raw material, a slurry coating step of coating a coating layer forming slurry which contains a cordierite forming raw material on four regions in a rotation area when each of two straight lines passing through the center of gravity of the cross section and extending in a diagonal direction of main quadrangular cells is rotated in a range of ±x° of the center of gravity in a circumferential surface, and a firing step of firing the honeycomb formed body on which the slurry is coated. The value x is in a range of 7 to 45, and the slurry is adjusted so that the coating layer has a porosity higher than that of the honeycomb structure body as much as 5% or more.

摘要： Provided are zeolite catalysts that allow reactions to proceed at temperatures as low as possible when lower olefins are produced from hydrocarbon feedstocks with low boiling points such as light naphtha, make it possible to make propylene yield higher than ethylene yield in the production of lower olefins, and have long lifetime.The zeolite catalysts are used in the production of lower olefins from hydrocarbon feedstocks with low boiling points such as light naphtha. The zeolite catalysts are MFI-type crystalline aluminosilicates containing iron atoms and have molar ratios of iron atoms to total moles of iron atoms and aluminum atoms in the range from 0.4 to 0.7. The use of the zeolite catalysts make it possible to increase propylene yield, to lower reaction temperatures, and to extend catalyst lifetime.

摘要： This invention is for a catalyst for conversion of hydrocarbons. The catalyst contains a zeolite with one element from Group 13, Group 14, or the first series transition metals and, optionally, germanium and/or aluminum in the zeolite framework. At least one Group 10 metal, such as platinum, is deposited on the zeolite. Examples of the elements in the framework are tin, boron, iron or titanium. The catalyst is prepared by synthesizing a zeolite with one element from Group 13, Group 14, or the first series transition metals and, optionally, germanium and/or aluminum in the zeolite framework; depositing the metal; and calcining after preparation of the zeolite and before or after depositing the metal. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with alkanes having 2 to 12 carbon atoms per molecule and recovering the product.
