The latest processes for desulfurization of liquefied gas

A production process for desulfurizing liquefied petroleum gas used in vehicles by adsorption, utilizing alumina gel as a carrier and basic catalysts based on cobalt titanate and zinc oxide as desulfurization adsorbents, for liquid-phase fixed-bed desulfurization under normal temperature and pressure； Liquefied petroleum gas is dried and dehydrated using activated alumina desiccants, then passes through a layer of hydrated alumina to absorb moisture. It is subsequently desulfurized using a specially formulated desulfurization adsorbent, filtered to remove impurities, and stored in a gas tank. A desulfurization adsorbent made from cobalt titanate, zinc oxide, and aluminum oxide gel was used to remove water and sulfur from liquefied petroleum gas produced in refineries, which **helped to reduce the emissions of SO2 in exhaust gases ； At the same time, this process is highly effective in removing organic polysulfides that are difficult to eliminate, addressing the issue of corrosion of vehicle engines and equipment caused by harmful substances present in automotive fuels. This opens up broad prospects for the use of liquefied petroleum gas produced by refineries as a clean fuel for vehicles. Just for reference
