Application of biodiesel derived from olive oil production wastes at marine diesel engine and evaluation of gasseous emission trends

As a carbon neutral fuel, biodiesel is one option in future IMO scenarios for reducing intensity shipping sector, and at same time emission of pollutants. Some oily wastes, such as waste from olive oil production, might be used production second-generation biodiesel. The current study looks into the effect on characteristics gaseous pollutant emissions NOx CO slow-speed two-stroke marine diesel engines that do not have any after-treatment devices or engine control technology installed to reduce emissions. While ship was berthed harbor, tests were performed two separate loads 210 rpm. powered by fuel blends 7%, 20%, 25% v/v derived wastes generated during processing. For lab conditions, base-catalyzed transesterification implemented. According findings, there are tendencies reduced when utilizing blended fuels.
