    • The present invention relates to an active and selective zeolite catalyst having MTT structure that is useful in skeletal isomerisation of light olefins. It also relates to a method for the manufacture of said catalyst. The method for the manufacture of the zeolite catalyst having MTT structure comprises the steps of a) Preparing of a gel mixture capable of forming crystalline material, and said mixture comprising sources of alkali or alkaline earth metal (M,) of an oxide of a trivalent element (X), of an oxide of a tetravalent element (Y), water and a directing agent (R), and said mixture having a composition, in terms of molar ratios, within the following ranges; (I) b) Maintaining of said mixture under sufficient conditions, including a temperature of from about 100° C. to about 250° C., under dynamic mode of stirring until crystals of said material are formed, recovering the material, and b) Removing of said directing agent (R) partly or totally with a calcination procedure, whereby a zeolite catalyst having MTT structure is obtained.

    • A process for converting an olefin feed to hydrocarbons suitable for fuel components or their feedstock. According to the process, an olefin feed, possibly together with another hydrocarbon feed, is contacted in a reactor with a catalyst in order to produce a hydrocarbon having at least one alkyl side chain. In the invention, the olefin feed is contacted with a particle-form fluidized catalyst in a circulating-bed reactor, wherein the catalyst forms the circulating bed of the reactor. When the operation is carried out in a circulating-bed reactor, the retention time of the feedstock is short. In this case, iso-olefins are formed quite selectively from n-olefins in isomerization. Since the useful life of the catalyst lengthens while the catalytic activity of the bed remains high for a long time, the conversion level also remains high. A long useful life of the catalyst is an economically highly significant advantage. In a circulating-bed reactor the regeneration of the catalyst can be carried out quite flexibly, and the operation of the reactor need not be interrupted for the duration of regeneration.
    • 将烯烃进料转化为适用于燃料组分或其原料的烃的方法。 根据该方法,烯烃进料可能与另一种烃进料一起在反应器中与催化剂接触,以便产生具有至少一个烷基侧链的烃。 在本发明中,烯烃进料在循环床反应器中与颗粒形式的流化催化剂接触,其中催化剂形成反应器的循环床。 当在循环床反应器中进行操作时,原料的停留时间短。 在这种情况下,异构烯烃在异构化中非常选择性地从正构烯烃形成。 由于催化剂的使用寿命延长,而床的催化活性长时间保持较高,转化率也保持较高。 催化剂的长期使用寿命是经济上显着的优势。 在循环床反应器中,可以相当灵活地进行催化剂的再生,并且在再生持续期间不需要中断反应器的操作。
