Synthesis of new composite materials for processing of methane into important petrochemical products

Abstract

The aim of this research was to develop the technology of new composite material synthesis for the processing of natural gas methane into olefins. The effects of technological parameters (temperature, volumetric rate, reaction mixture composition) on methane’s oxidative conversion into important petrochemical products has been studied. The paper presents data on methods developed for synthesis and physicochemical characteristics of catalysts. The technological parameters of the process conducted by means of integrated automated laboratory setup were optimized. It has been established that 10% K-30% Mn-10% Nb/50% glycine catalyst prepared by the solution combustion synthesis (SHS) method in solution was active for olefin formation at oxidative transformation of mixture 41.8% CH4+16.2% O2+42% Ar at a volumetric velocity of 3500 h-1. It was determined that at T=800°С, yields of C2H6 and C2H4 were 3.3 and 14.3%, respectively.
