1) full hydrogen tech-nique
2) hydrogenation process
Improving the hydrogenation process to extend the service life of catalyst;
The requirement to effectively process these crudes has accelerated the de- velopment of world hydrogenation processes,and hydrocracking and hydrotreating capacities have been growing at a greater pace.
The problems of China s base oil processes under the high prices of crude oil are pointed out as follows:①for the traditional base oil process,the problem is that the great diversity of refining crude oil leads to decline in the quality of base oil and corrosion towards facilities;②and for the base oil hydrogenation process,the problem is mainly the operation under capacity.
3) hydrogen making process
4) dehydrogenation process
Reasonable application of dehydrogenation process during plate production;
5) Hydrogen relieving technique
6) HD process
The effect of various H-desorption pressures in HD process on sintered NdFeB permanent magnets is studied.
It shows that to choose an optimal H-desorption grade in HD process is important .
