Abstract
The present invention relates to an amorphous adsorbent composition capable of purifying a gaseous hydrocarbon fraction and methods for synthesizing the composition. The composition is advantageously capable of filtering non-combustible contaminants for increasing the quality and heating value of a gaseous hydrocarbon such as methane. The composition comprises a zeolite based framework that is at least partially collapsed and capable of selectively adsorbing and desorbing gaseous components such as methane and carbon dioxide for purifying the gaseous hydrocarbon fraction.
