Direct Catalytic Conversion of Biogas Methane to Formaldehyde

چکیده
Efficient Solid waste utilization is a challenging task. In rural areas organic wastes like cattle waste is available in abundant, which is not utilized in the valuable forms and in urban areas it is disposed off in an improper manner. In this study biogas primarily from cattle waste was generated by using a fabricated anaerobic biogas digester. The methane is easily separated from biogas by removal of CO2 using 40% KOH solution in three steps. After purification, direct conversion of methane to formaldehyde, which is a useful organic chemical using various metal oxide catalysts like SiO2, V2O5/SiO2, MoO3/SiO2 was investigated in a tubular reactor. The yields of methane conversion using various prepared catalysts was studied at varying temperature (from 400 C to 850 C) and at constant pressure (one atmospheric) over different catalyst beds. Among the various catalysts that were studied for methane conversion, the results showed that the V2O5/SiO2 catalyst favours the maximum formaldehyde conversion.

The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...
