The paper deals with the technological characteristic used Lanthanum basespheroiditic agent in a fountry and better synthetical mechanical properties through con-trasting trial on technology between Lanthanum and Cerium base spheroiditic agent nowoften used in fountries, and in this paper, the spheroidization mechanism for Lanthanumbase spheroiditic agent is preliminarily studied,too.

The CeO2-based catalysts with different supports(TiO2,MgO and Al2O3) were investigated in the direct partial oxidation of methane to syngas using their lattice oxygen in molten salt.
