Summary: This study investigated the performance of different types of surfactants on the surface activity, emulsion size, and surface charge of five oil samples. The effects of various parameters on the interfacial tension of crude oil/surfactant solutions were comprehensively analyzed. The results showed that the properties of the surfactants, crude oil type, and ionic strength influenced the interfacial tension, surface charge, and microemulsion size, but not in a straightforward manner. Among the surfactants considered, the cationic surfactant showed the lowest dependency on the crude oil type, while the non-ionic surfactant showed the highest dependency. CTAB cationic surfactant exhibited the most efficient performance with a microemulsion size of 102 nm and surface charge near the isoelectric point.

Summary: Ammonia and hydrogen are carbon-free fuels with great potential for energy systems. While hydrogen has high expectations for a carbon-free economy, challenges in storage, distribution, and infrastructure delay its full implementation. Ammonia, on the other hand, delivers high energy density with an established infrastructure, making it a sustainable fuel solution. Constraints in using pure ammonia have led to the development of new strategies for application.
