An unsupported NiMo catalyst was modified by β-zeolite nanoclusters synthesized by the hydrothermal method. The effect of the nanoclusters on the acidity of unsupported catalyst was studied. Results showed that the Lewis acid and the total acid amount of the unsupported catalyst were improved. Indicating that the β-zeolite nanoclusters was successfully introduced into the unsupported catalyst. And the catalytic activity results showed that the introduction of β-zeolite nanoclusters not only led to the higher desulphurization and isomerization activity, but also improved the ratio of direct desulfurization paths (DDS), which is in favor of reducing hydrogen consumption.

通过水热法合成的β-沸石纳米团簇对无载体的Ni Mo催化剂进行了改性。研究了纳米团簇对无载体催化剂酸度的影响。结果表明，路易斯酸和无载体催化剂的总酸量均得到改善。表明β-沸石纳米团簇已成功引入无载体催化剂中。催化活性结果表明，β-沸石纳米团簇的引入不仅导致较高的脱硫和异构化活性，而且提高了直接脱硫路径（DDS）的比例，有利于减少氢的消耗。
