Abstract

The analysis of the method of reducing gas obtaining by natural gas air reforming with cooling and drying of obtained products on the first stage of the process, their heat treatment in the catalyst layer, chilling and drying — on the second stage is made. It is determined that the temperature of a thermal gas treatment at the second stage of the process, shall not be less than 850–950 °C, which allows to increase the ratio (CO + H2)/CO2 in the resulting reducing gas. The values of the minimum temperature of gas processing on the second stage of the process depending on the pressure in the system are calculated. The total heat effect of chemical reactions depending on the temperature of gas heat treatment at different pressure is defined. It is shown the possibility of compensation for the heat expenditure required for the chemical reactions behavior in the temperature region above 850 °C by gas overheating in excess of the required level prior to its entering into catalyst bed on the second stage of the process.
