硫醇

Octyl mercaptan may exist in the base oil or continue to decompose to volatile low molecular mercaptan or H 2S.

辛硫醇有可能存在于基础油中，或在摩擦热的作用下继续分解生成挥发性的低分子硫醇或硫化氢挥发掉

There are mainly two ways to sweeten light oils: removal of mercaptan from the lightoils, and oxidation of mercaptan to less harmful disulfide.

轻质油品脱臭主要从两个途径达到脱臭目的，一是除去油品中的硫醇，二是将油品中的硫醇转化为危害性较小的二硫化物。

The results of the dissertation were concluded as follows:(1) It is essential to deposit a basic additive on the Mo-based catalysts for the synthesis of CH_3SH. The potassium-doped Mo-based catalysts exhibit the highest activity than that of the catalysts doped with the otherⅠA andⅡA group basic promoters. H_2-TPR and LRS characterizations suggest that the addition of a base leads to the transformation of octahedrally coordinated Mo to tetrahedrally coordinated Mo, thus leads to the split of low temperature reduction peaks. The interaction between the basic components and Mo lead to the formation of B-Mo interface phase, which are closely correlated with the formation of CH_3SH.(2) It has been found that Fe, Co, Ni and Te have evident promoting effects for the K-Mo/SiO_2 catalysts.

主要结果归纳如下：(1)在Mo基催化剂中，必须添加碱才具有可观的合成甲硫醇活性，在IA和IIA族元素中，K是最佳的碱促进剂，当K/Mo摩尔比为2，前驱体为K_2CO_3，采用共浸法制备的K-Mo催化剂活性最高。H_2-TPR和LRS表征显示，碱的加入导致表面八面体钼氧物种向四面体转化，催化剂的低温还原峰发生分裂，碱助剂与钼之间存在强相互作用形成了B-Mo"界面相"，该物种与合成甲硫醇密切相关。
