ABSTRACT
ABSTRACT The global use of fossil energy sources has led to the need to develop technologies capable of mitigating its consequences. One such option is anaerobic biodigestion, which is already scientifically well-established, although the use of its main products (biogas and biomethane) still requires further development before they can be employed in automotive vehicles, largely due to technical issues concerning their storage. The storage of methane using adsorption (Adsorbed Natural Gas - ANG) is a technology that requires less energy and moderate pressures and temperatures. However, the main storage techniques continue to be those that involve high pressures and/or cryogenic temperatures. The present work evaluates the performance of an unprecedented prototype developed by UFPR for the storage of methane by adsorption, employing commercial activated carbon. The factorial design (2²) indicated that the storage capacity of the system was 39.41 V /V using activated carbon, and the desorption process was effective at 60ºC. Thus, the use of adsorbents of low cost and easy access can provide very interesting results (>100 V / V), which contributes to make the technology viable.
