Abstract: Abnormal analysis of geochemical elements is a significant link in the mineral resources prediction.
Due to the polyphyleticism of the metallogenic material and ore-forming process is characterized by multiple stages. there are two type of the metallogenic elements ,i.e., main ore-forming elements and associated elements.
And the composition of the sample material may also be the result of a variety of geochemical action.

Experimental
Materials.
Three raw materials can be converted to hydrocarbons and obtained the required components through deoxygenation and cracking in a single system.
High temperature promoted aromatized and coked, as the temperature increased, deactivation of the catalyst increased and three raw materials represented different laws, castor oil and rubber seed oil were more easily to cause deactivation.

Keywords: BaCo0.7Fe0.2Nb0.1O3-δ; Carbon dioxide; Stability; Oxygen permeation
Abstract Mixed ionic-electronic conducting BaCo0.7Fe0.2Nb0.1O3-δ perovskite is a newly developed promising ceramic membrane material.
Starting raw materials were ball milled in ethanol using zirconia grinding media for 24hrs and calcined at 1223K for 10hrs.
The MIEC perovskite materials must maintain the perovskite structure under working conditions to ensure the stable oxygen permeation flux.
After annealed under pure oxygen, minute hexagonal structure is appeared in the sample, which illustrates a suitable level of oxygen vacancy in compound would stabilize the cubic phase of material.
