Cogasification
of olive pomace, almond shell, and petcoke was carried
out by thermogravimetric analysis coupled with mass spectrometry.
Binary and ternary blends were compared in terms of their reactivity,
outlet-gas emissions, H2/CO ratios of effluents, and synergistic
effect. Synergistic and antagonistic effects were observed with cogasification
of blends, but that depended on the ratios of raw materials in the
feed. In this regard, the higher the biomass content, the greater
the weight loss, the higher the decomposition rate and, thus, the
higher the gasification reactivity. Moreover, the synergistic effect
on the gasification of the
raw materials did not show a clear trend in gas emissions. In general,
the higher the biomass content, the greater the H2 and
CO2 yields, and the less CO was released. On comparing
binary and ternary blends, it was seen that the former presented better
results in most parameters studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
