    • The invention refers to a process for the obtainment of a catalyst useful in the isomerization of light paraffins, fundamentally based on acid treatment of a synthetic mordenite at temperatures between 40.degree. and 100.degree. C. followed by treatment with steam-air at temperatures between 300.degree. and 600.degree. C. which makes is possible to optimize the SiO.sub.2 Al.sub.2 O.sub.3 framework ratio and the amount of extraframework aluminum of the zeolite. The mordenite thus obtained is mixed with an inorganic refractory oxide such as Al.sub.2 O.sub.3 and a metal of group VIII, basically Pt, is added in an amount between 0.1 and 0.5% by weight referred to the final catalyst.The catalyst has been tested in the isomerization of light refinery fractions (C.sub.5 and C.sub.6) and has a high activity and selectively of branched isomers with a low production of gases and a high octane number for the light gasoline obtained.
    • 本发明涉及获得可用于轻链烷烃异构化的催化剂的方法,其基本上是基于在40℃至100℃之间的合成丝光沸石的酸处理,然后在300℃的温度下用蒸汽 - 空气处理 DEG和600℃,这使得可以优化SiO 2 Al 2 O 3骨架比和沸石的粉末铝的量。 由此获得的丝光沸石与无机耐火氧化物如Al 2 O 3和基本上Pt的金属基本上相加,以与最终催化剂相关的0.1至0.5重量%的量加入。 催化剂已经在轻馏分馏分(C5和C6)的异构化中进行了测试,并且具有高活性和选择性地具有支链异构体,其中所得到的轻质汽油的气体产量低,辛烷值高。
