In preparation of motor fuel, the bio-oil from pyrolysis of biomass must be further upgraded so as to improve its quality. However the catalyst used in the cracking reaction is easy to lose its activity due to being coked, so that it is important to study the coke formation and its effects on the catalyst activity in the cracking process.

为了获得高质量生物质燃料油，需要对生物质直接裂解得到的生物质油进行催化裂解精制：精制过程中催化剂容易结焦，对精制反应产生很大影响。

The components of the catalyst are sulfurated more completely with a longer reaction time. But the catalyst congregates into a large volume ball with a low BET surface area after a certain reaction. So the best range of reaction time is from 60 to 90 minutes.

研究发现，虽然硫化时间的延长可提高催化剂中金属组分的硫化物含量，但超过一定反应时间可导致硫化物过度结晶聚集，颗粒度增大，比表面下降，较佳的反应时间为60～90 min。

Compared with the conventional catalyst, the complex catalyst improved methanol anodic oxidation activity by 46 percent. The reason that it deceases the activation energy for the methanol and its ramification electro-oxidation reaction was estimated to be its special complex Keggin structure.

测试表明该添加剂降低了甲醇及其电氧化中间产物转化的活化能，改善了电极内部的质子传输状况，对甲醇的电化学氧化过程具有明显的促进作用，该复合催化剂与常规的Pt-Ru/C催化剂相比，甲醇的阳极氧化电流提高了46%。
