Mesoporous nano Ni-Al2O3 catalyst for CO2 methanation in a continuously stirred tank reactor
نویسندگان
چکیده
Mesoporous nano Ni-Al2O3 catalysts were prepared by using Pluronic P123 (P123) and fatty alcohol polyoxyethylene ether (AEO-7) as structure directing agents (SDAs), applied for CO2 methanation in a continuously stirred tank reactor (CSTR). Compared with NiAl-A AEO-7 SDA NiAl-N without SDA, NiAl-P possesses ordered mesopores, high Ni dispersion, large metal surface area amounts of adsorbed CO2, which benefits conversion. Under the conditions 1.0 MPa, 300 °C H2/CO2 ratio 4, shows highest conversion 74.0% CH4 yield 73.6%.

متن کاملKinetic studies of CO2 methanation over a Ni/γ-Al2O3 catalyst.
The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...
متن کاملBifurcation Phenomena for an Oxidation Reaction in a Continuously Stirred Tank Reactor. Ii Diabatic Operation
We extend an investigation into the bifurcation phenomena exhibited by an oxidation reaction in an adiabatic reactor to the case of a diabatic reactor. The primary bifurcation parameter is the fuel fraction; the inflow pressure and inflow temperature are the secondary bifurcation parameters. The inclusion of heat loss in the model does not change the static steady-state bifurcation diagram; the...
متن کاملMATLAB Simulation for Continuous Stirred Tank Reactor
This paper presents control of the nonlinear system represented by a Continuous Stirred Tank Reactor (CSTR) using MATLAB’s Graphical User Interface (GUI). This simulation provides computation for various values of the input variables, which made this program universal for the wide range of the users without theoretical knowledge about modeling, simulation, and control.

Different mixtures were digested in a single-stage, batch, mixed, laboratory scale mesophilic anaerobic digester at the Biomass Research Centre Laboratory (University of Perugia). The yield and the composition of biogas from the different substrates were evaluated and the cumulative curves were estimated. Two experimental campaigns were carried out, the first on three mixtures (chicken, pig and...
