Description

 The obtained Ni-Al2O3-MxOy/cordierite (M: Na, K, La, Ce) catalysts for the biogas conversion process (CH4 + CO2) are characterized by high carbon resistance, that ensures their stability in the process of methan dry reforming. Modification of of Ni-Al2O3/cordierite compositions with rare earth and alkali metal oxides extends the method of intensification of the process of VCM by introducing into the reaction gas mixture of oxygen additives, which allows to lower the temperature of reaching high rates of hydrogen output (synthesis gas), slowing down carbon deposition on a catalyst surface. It is shown that zeolite Ni-BEA catalysts with different Si/Al modulus are high activity and stability in the DMR process at relatively low temperatures (99% of methane conversion at T ≤ 700 ° C). Dealumination has been found to significantly reduce the concentration of Al-containing acid centers on the surface of the catalyst, which are usually the centers of carbon formation, which impedes the widespread use of zeolites as carriers of DRM catalytic compositions.
