Approaches to enhance the value of Ca Voi Xanh gas via its transformation into nanocarbon materials
Abstract
Ca Voi Xanh gas has high contents of impurities, namely H2S, CO2 and N2. The transformation of this gas into high-value products is a potential approach to enhance its value without pre-treatment. In fact, it is a promising feedstock for nanocarbon production, including carbon nanotubes (CNT) and carbon nanofibres (CNF). Their applications can be found in various areas of which markets are promising. Two methods for nanocarbon production can be considered, namely methane decomposition and dry reforming of methane. Methane decomposition brings higher nanocarbon yields while dry reforming of methane can produce better quality nanocarbon products. A number of issues need to be solved before these processes can be commercialised, such as improvements of nanocarbon yields and their recovery methods.
