Desulfurizing Coal By Chlorinolysis and Hydrogenation
85 percent of organic and pyritic sulfur in coal removed by combination of chlorinolysis and hydrogeneration. Coal is fed to hydrogenator after chlorination. Coal flows against hydrogen current increasing mixing and reducing hydrogen consumption. Excess hydrogen is recovered from gaseous reaction products. Product coal contained 62.5 percent less total sulfur than same coal after chlorination.
