Modelling of methane dry reforming over Ni/CaO–Al2O3 catalyst

This paper presents the results of investigations into dry methane reforming (DMR). The process was aimed at obtaining synthesis gas required for the production of dimethyl ether (DME). The effect of temperature, pressure and inlet gas composition on the process was determined in the experimental part of this work. The tests were carried out in a laboratory tubular reactor over a Ni/CaO–Al2O3 catalyst. The obtained experimental results were used to verify literature kinetic data and to develop a mathematical model of the DMR process.

In order to produce valuable syngas, industrial processes of dry reforming of methane and steam reforming of methane must be further developed. This paper is focused on reviewing recently examined catalysts, supporting the mentioned technologies. In both processes the most popular active material choice is usually nickel, due to its good availability. On the other hand, noble metals, such as ruthenium, rhodium or platinum, provide better performance, however the solution is not cost-effective. Materials used as a support influence the catalytic activity. Oxides with basic properties, such as MgO, Al2 O3 , CeO2 , are frequently used as carriers. One of the most promising materials for reforming of methane technologies are hydrotalcites, due to adjustable composition, acid-base properties and possibility of incorporation of various metals and complexes.
