PURPOSE: A process for preparing metal phosphide catalyst is provided to improve the activation per unit area for metal phoshpide catalyst by generating particle size distribution at narrow margin. CONSTITUTION: Nickel(II) chloride hexahydrate 1.82 g(1.5 mmol Ni loading) and sodium hypophosphite 1.64 g(3 mmol P loading) are fused in a distilled water 40 ml. The aqueous solution is stirred with an alumina carrier. The dissolution including the alumina carrier is slowly deposited at 80°C. The solution is dried at 80°C for 8 hours. The nitrogen flows at 100sccm for dried solid, and the temperature of the solid is increased up to 300°C.
Abstract:
Provided is a method for purifying pyrolysis oil form waste containing hydrocarbon. The pyrolysis oil of the waste containing hydrocarbon is divided into light oil and heavy oil. The light oil is processed using a first hydro-cracking catalyst. The heavy oil is processed using a second hydro-cracking catalyst in a lower liquid hour space velocity than the hydro-cracking process of the light oil.
Abstract:
The present invention relates to a 6-hydroxy-2-naphthoic acid manufacturing method using naphthalene and, more specifically, to a 6-hydroxy-2-naphthoic acid manufacturing method comprising: a step of manufacturing sulfated naphthalene by performing sulfating reaction on naphthalene; a step of manufacturing sulfuric acid naphthalene alkali salt by performing neutralization reaction on sulfated naphthalene; a step of manufacturing beta naphthol alkali salt by performing hydrolysis reaction on sulfuric acid naphthalene alkali salt; and a step of performing carboxylation reaction on beta naphthol alkali salt. The present invention can manufacture 6-hydroxy-2-naphthoic acids from naphthalene through a simplified process when compared to an existing process by consecutively applying beta naphthol potassium salt as a reactant of carboxylation reaction by allowing the beta naphthol potassium salt to be a product of naphthalene hydroxylation reaction.
