Abstract

Dimethyl ether (DME) gas is expected to gradually replace the LPG supply in order to maintain national energy sustainability in Indonesia, thus study on DME storage as fuel gas is needed. Aluminum-based Metal Organic Framework (Al-MOF) have been explored in the last decades and is one of many potential candidates for DME gas adsorbent in a fuel tank. Moreover, Indonesia has a high abundance of aluminum ores that can be used to produce factory-scale Al-MOF. This work tries to identify some possible Al-MOF which can potentially be applied in the DME fuel tank storage. A systematic literature review was used in this study, based on scientific peer-reviewed journal articles written in English, especially articles published in the last 10 years (2012-2022). This study finds that there are several possible top candidates to be explored for DME adsorbent based on pore size and surface area of the synthesized MOF, namely Al-BDC and Al-BTC, in which BDC = 1,4-benzene dicarboxylate and BTC = 1,3,5-benzene tricarboxylate. Each candidates shows different pore morphology and physical properties but remains possible to be developed in practical use. In addition, the proposed Al-MOF are feasible to produce in industrial scale and has good thermal stability. Nevertheless, further research on gas adsorption-desorption using real DME gas samples, including computational simulation, is required before these adsorbents were used in actual forms and real conditions.
