Blog. what are the 6 major sources of methane? - dsinm.com In 2021, about 17.5 billion gallons of biofuels were produced in the United States and about 16.8 billion gallons were consumed. It is produced from the anaerobic (without oxygen) breakdown of organic matter that can include anything ranging from manure to sewage to plant material and even crops. The equipment used to create the right anaerobic conditions (occurring in the absence of oxygen) and capture the gas is called a biodigester, which acts as a mechanical stomach. These results clearly show that non-thermal plasmas offer a promising solution to overcome the thermodynamic barrier for the direct transformation of CH4and CO2into a range of strategically important platform chemicals and synthetic fuels at ambient conditions, said Dr. Xin Tu, from the University of Liverpools department of electrical engineering.

Conversion to liquid or gaseous fuels. Typically, the conversion will require high temperature, energy intensive syngas production process and high pressure syngas processing for chemical synthesis. endstream endobj startxref Digestion carried out by these microorganisms creates methane, which can be used as it is locally or upgraded to biogas equivalent to natural gas quality, enabling the transport of the biogas over longer distances. The United States was a net exporter of about 0.8 billion gallons of biofuels in 2021, with fuel ethanol accounting for the largest share of gross and net exports of biofuels. The researchers from the University of Liverpool have developed a plasma synthesis process for a direct, one-step activation . At times, concentrations can reach as high as 75%. It is estimated that under ideal conditions, 10 kg of biomass can produce 3m of biogas. Furthermore, they have been identified in syntrophic relationships with sulfur and iron reducing bacteria, and there is potential that they could be combined with other microbes to facilitate the final degradation of biomass waste into usable and storable bioenergy in the form of methane.
