Longguang LG-T611 type high efficiency dual function ferromanganese desulfurizer is the transformation - absorption type, dual function and moderate temperature desulfurizer. The main characteristic is the higher hydr-conversion efficiency of the refractory organic sulfur. It could replace Cobalt, molybdenum and Zinc Oxide to be the organic sulfur and hydrogen sulfide in the refined light oil, natural gas, oil field gas, coke oven, carbon dioxide, nitrogen and hydrogen (the total sulfur could reach to 500×10^-6).
