摘要： PURPOSE: To provide a crystalline aluminosilicate composition containing transition elements, giving seven diffraction lines each having specific lattice spacing and specific relative intensity in the X-ray diffraction pattern, and able to be easily regenerated and activated after using as a catalyst.
CONSTITUTION: A crystalline aluminosilicate composition containing transition elements, and giving seven diffraction lines exhibiting the lattice spacings and relative intensities shown in the table in the X-ray diffraction pattern (the relative intensity is given by taking the intensity of either diffraction line corresponding to the lattice spacing of 10.0±0.4 or 3.83±0.05Å as 100). The composition is useful as an adsorbent or a catalyst. When it is used as a catalyst, it can be easily regenerated and activated by heating at a temperature considerably lower than the spontaneous ignition point of the tar deposited on the catalyst (about 530°C), e.g. at 380°C. The composition can be prepared, e.g. by adding a transition element compound or a transition metal to the aqueous raw material mixture liquid for the preparation of crystalline aluminosilicate.

摘要： PURPOSE: In preparing an olefin from methanol and/or dimethyl ether, to reduce the amount of a diluent used, to improve rate of reaction and selectivity, to prevent a catalyst from deteriorating, by reducing rate of feed of a raw material per crosssectional area of catalytic layer and per hour.
CONSTITUTION: Using a catalyst comprising crystalline aluminosilicate zeolite (e.g., FZ-1 zeolite, etc.), olefin is prepared from methanol and/or dimethyl ether by a catalytic reactor of fixed bed. In the reaction, methanol and/or dimethyl ether are fed in amounts in range from 0.3W15g per sec per crosssectional area of catalyst, and the amount of a diluent used is reduced. The heat of reaction produced per crosssectional area of catalytic layer in a direction perpendicular to the direction of the raw material and per hour can be made small. The reduction in the amount of the feed of the diluent can save energy.
