Methods of oxidative ammonia-sulfate leaching of natural raw materials of complex composition are widely used in industry [6-7].
In this case, the general model of cascade consists of three models of reactors arranged in series and connected by material flows of reagents.
The model of each reactor consists of blocks of chemical kinetics, hydrodynamics, and material balances.

Introduction SiO2 aerogel is one of nanometer porous materials with light mass.
This material possessed excellent thermal insulation property, because of the fine and porous nanometer structure, so it always have good extensive application prospect [1-5].

Especially, the topology optimization is referred to as the FE-based techniques for an optimal distribution of void and materials [5].
The approach presented in this paper is This research is supported by the National Natural Science Foundation of China Grant#50675027 simulated through ANSYS to verify the effectiveness and feasibility.
The assumption that the material density and material properties of the non-linear relationship as follows:    = = 1 1 vv EE a η (2) Where 1E is the elastic modulus of the actual material ( 1>α ), 1v is the Poisson's ratio.
And then we elected the material properties of the robot arm.

Materials and methods Materials It was studied a bentonite clay sample known commercially as Brasgel PA and two samples of shales high reactivity from two regions of the country: Araripe Basin-EP and Reconcavo Baiano from Candeias formation and Parnaíba Basin Shale from Pimenteiras-TO formation.
It was used an EDX-720 equipment from Shimadzu located at the Laboratory Characterization of Materials Engineering/CCT/UFCG.
