Catalytic Reforming of Biogas to Produce Environmentally Friendly High Effective Fuels

Abstract

In today's world, environmental issues are becoming more and more relevant. In connection with the growing industrial activity of mankind, a large amount of CH4 and CO2 is emitted into the atmosphere. Since the start of the Industrial Revolution, CO2 concentrations have increased by more than 45 %, from 280 ppm in the mid-18th century to 415 ppm in 2019. Biogas mainly consists of 50 - 87 % methane, 13 - 50 % carbon dioxide and other gases. Conversion of biogas solves two important issues related to the utilization of greenhouse gases and the possibility of obtaining synthesis-gas with an optimal ratio of 1 : 1. Carrying out the Fischer-Tropsch synthesis reaction, the production of gasoline, jet fuel, ethanol and other oxygen-containing compounds is possible at this ratio. Development of new applied catalysts, as well as optimal technological conditions for synthesis-gas production in the process of catalytic conversion of biogas, is a contribution to the petrochemical sector, namely gas processing. Optimal conditions for the oxidative conversion of a model mixture of biogas into synthesis-gas on Ni-, Co- monometallic and Ni-Co bimetallic catalysts at different ratios to obtain maximum yield of products with rational consumption of raw materials and energy were determined: T = 700 °C, GHSV = 6,000 h-1, CH4 : CO2 : Ar = 1 : 1 : 1 ratio in the reaction mixture.
