PURPOSE:To prepare hydrocarbon with a high conversion over a long period, by using a catalyst consisting of a specified crystalline silicate. CONSTITUTION:An aqueous mixt. of (A) silica source, (B) alumina source, (C) alkali (alkaline earth) metal source, (D) tetra(1-4C alkyl)ammonium salt and (E) methanol in which A/B is 10 or higher, E/water is 0.1-10, E/A is 5-100, hydroxy ion/A is 0.01-0.5 (excluding hydroxy ion from the organic base) and D/A is 0.01-1.0 by mol, is made to undergo crystallization reaction at 110-300 deg.C for 5hr-10 days. The reaction product is washed with water and dried at around 120 deg.C to obtain a catalyst consisting of a crystalline silicate which is shown by the molar ratio equation [where M is H or an alkali (alkaline earth) metal; n is the valency of M; p is 0.3-3.0 and q is 10 or higher] and has an X-ray diffraction pattern of the table when burned at 550 deg.C in the air. Then an oxygen-contg. compd., e.g. methanol, is brought into contact with the catalyst at 250-600 deg.C under normal or high pressure at a weight space velocity of 0.1-50hr<-1>. |
