摘要： Niobium, Nb, is refined from FeNb by electron beam melt refining. The amount of the impurities in the FeNb which form suboxides with oxygen is optionally determined. Sufficient oxygen is added to form oxides with these impurities. The electron beam melt refining process is carried out at a sufficiently high temperature and under a sufficiently low vacuum so that the impurities are removed as oxides from the liquid Nb and the purified Nb is recovered. Preferably the oxygen is added as an oxygen-containing compound such as Nb.sub.2 O.sub.5. The recovered Nb can be subjected to additional electron beam melt refining cycles to obtain the desired purity.

摘要： A delayed coking unit has a thermal shock-resistant, erosion-resistant internal lining to reduce thermally-induced mechanical stresses in the pressure boundary of the coke drum. The lining is effective to reduce or mitigate the transient thermal stress that occurs in the pressure boundary of the coke drum and to reduce or minimize the high thermal stress resulting from temperature differentials at the skirt-to-shell junction.
