The invention provides methods for converting hydrocarbons as starting material by industrial fixed-bed reaction processes with a zeolite shaped catalyst which has a low content of inorganic binder and a high pore volume and which shows high catalytic activity, long catalyst life and high crushing strength. A zeolite shaped catalyst used in the methods of the invention includes zeolite and an inorganic binder and is obtained by kneading zeolite, a starting material of an inorganic binder, shaping auxiliary(ies), organic polymer particles having an average diameter of 0.1 to 6 μm and water into a kneaded product, and extruding, drying and calcining the kneaded product; and the zeolite shaped catalyst has a zeolite component content of not less than 60 wt % relative to the total weight, a pore volume of 0.4 to 1.0 ml/g, a half-volume pore diameter of 80 to 500 nm and a crushing strength of not less than 0.9 kg.
A hydrocarbon conversion method comprising catalytically cracking hydrocarbon starting material containing olefins into olefins that are lower than the starting material with use of a zeolite shaped catalyst, the zeolite shaped catalyst being obtained by kneading zeolite powder, a starting material of an inorganic binder, shaping auxiliary (ies) organic polymer particles having an average diameter of 0.1 to 6 μm and water into a kneaded product, and extruding, drying and calcining the kneaded product.
