Researchers at the startup have developed two catalytic adsorbents — AdE-Sorb and AdE-Sulfur — for ultra-deep desulfurization of diesel. Ultra-deep desulfurization reduces the sulfur content in diesel to less than 15 ppm. These adsorbents consist of clusters of catalytic metals, such as Ni, supported on zinc oxide (ZnO) nanowires.

Response surface methodology (RSM) was selected to optimize a desulfurization process with metal based ionic liquids ([Bmim]Cl/CoCl2) and potassium monopersulfate (PMS) together to remove benzothiophene (BT) from octane (simulating oil). The four experimental conditions of PMS dosage, [Bmim]Cl/CoCl2 dosage, temperature, and reaction time were investigated.

However, there is a limit to the cost reduction that can be achieved as hydro-desulfurization (HDS) chemistry requires elevated temperature and pressure for deep desulfurization and, of course, consumes hydrogen in the process. Hydro-desulfurization also cannot readily achieve the very low sulfur levels envisaged for future "zero sulfur" fuels.

Flue-gas desulfurization - Wikipedia

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
