PURPOSE: A sulfide absorber for a solvent extracting process of coal and a sulfide absorption method using the same and coal purifying method are provided to effectively remove sulfide in organic solvent containing plastic component extract by using reactor including absorption. CONSTITUTION: A coal melting storage tank(10) stores an organic solvent. The stored organic solvent is moved to a reactor through high-pressure liquid pump(20). The reactor includes an absorbent(30). The reactor is heated by a high-temperature furnace(40). A pressure gauge(50) displays pressured in the reactor. The pressure is controlled by a pressure control valve(60). The absorption reaction of organic solvent is operated. The processed organic solvent is collected with a sample collecting container(70).

PURPOSE: A catalyst for acid components in high TAN crude oil and a manufacturing method thereof are provided to especially remove naphthenic acid among the acid components, and to improve activity and stability under acidic atmosphere. CONSTITUTION: A catalyst used for removing acid components in high TAN crude oil includes alkaline earth metal silicate or alkaline earth metal aluminate which is gained by reacting silicate or aluminate anions with alkaline earth metal cations. A molar ratio of alkaline earth metal/Si or Al is 10 or less. The catalyst is manufactured by a high-temperature plasticity method, a sedimentation method or a sol-gel method. The catalyst is used at a temperature of 150 °C ~ 500 °C. The catalyst for removing the acid components is a natural mineral of forsterite, talc or enstatite.
