The metals, such as Fe, Cu and Co, which can be reduced by KBH〓, can not change the catalytic properties obviously if only small amount of them are added to Ni-B alloys; those who can not react with KBH〓, such as Zn〓, are washed out during the preparation, so they also can not change the catalytic properties; while addition of the elements in VIB group, such as Cr, Mo and W, can increase the hydrogenation activity magnificently.

同样，我们通过添加第三组分来修饰Ni-B合金，可以被还原的金属，如Fe、Co、Cu等，少量添加并不能明显改变其反应性能；而与KBH〓不发生反应的金属，如Zn，以离子形式加入后，除了少量离子被吸附在催化剂表面外，基本不残留在催化剂里，因此对反应性能也没有太大的改变；只有VIB族元素，如Cr、Mo、W的加入才会很大改进Ni-B催化剂在蒽醌加氢中的催化性能，尤以Cr的修饰作用最好。

The flame-retardant/smoke-suppressant of PVC may be divided into three kinds. The first is FRs , includes the compounds lying in IVB～VIB, such as TiO〓, V〓O〓, Cr〓O〓 and MoO〓; The second is FRs , includes the compounds lying in VⅡB～IB, such as MnO〓, Fe〓O〓, Co〓O〓, CuO and ZnO. The third is FRs , includes the compounds of subgroup A, for example Mg 〓, Al 〓, Sb〓O〓, carbonate and phosphate.

PVC的阻燃抑烟剂可分为三大类，第一类阻燃抑烟剂为元素周期表中IVB～VIB族的化合物，以TiO〓，V〓O〓，Cr〓O〓和MoO〓为代表，第二类阻燃抑烟剂为元素周期表中VⅡB～ⅡB族的化合物，以MnO〓，Fe〓O〓，Co〓O〓，CuO和ZnO为代表，第三类阻燃抑烟剂为三氧化二锑，氢氧化镁，氢氧化铝等主族元素的化合物。

The higher gasification temperature, the higher the relative enrichments of As, Cd, Co, Cr, Cu, Mg, Ni, Pb, Se and the lower of Zn in the high temperature coke and the low temperature coke.

痕量元素在高、低温焦中受气化温度影响变化趋势相同，即随着气化温度的升高，As、Cd、Co、Cr、Cu、Mg、Ni、Pb、Se的相对富集系数增加，Zn的相对富集系数减小，Mn、Hg、V、Sr的相对富集系数变化很小。

There are other factors to influence the occurrence of trace elements. The higher gasification temperature, the higher the relative enrichments of As, Cd, Co, Cr, Cu, Mg, Ni, Pb, Se and the lower of Zn in the high temperature coke and the low temperature coke. The RRE of Mn, Hg, V, Sr are not affected by gasification temperature in the high temperature coke and the low temperature coke.
