Abstract:
PURPOSE: An apparatus for simultaneous production of synthetic oil and electricity is provided to synthesize synthetic oil by supplying synthetic gas to a Fischer-Tropsch synthesis reactor unit. CONSTITUTION: A steam methane modifier(1) generates a synthetic gas with a H2/CO ratio of 3:1 or more by modifying supplied natural gas. A first and a second heat exchanger(21,22) are installed in a heat exchanger supply pipe(2), to supply high temperature synthetic gas to a pressure-changing absorption separator(3). The pressure-changing absorption separator separates the synthetic gas into a synthetic gas with H2/CO ratio of 2:1, and high purity hydrogen, and supplies the same to a synthetic gas supply pipe and high purity hydrogen supply pipe, respectively. A Fischer-Tropsch synthesis reactor unit generates electricity by using the high purity hydrogen. A methane heat exchange supply pipe(6) has a third heat exchanger(61) to increase the temperature of methane, and supplies the methane.

Abstract:
PURPOSE: The secondary solvent for removing solvent compound and a removing method of sulfur compound using the same are provided to remove sulfur compound with high efficiency from coal extract of low class coal, and reduce cost of the whole procedure by showing high desulfurization efficiency from a small amount of secondary solvent. CONSTITUTION: The secondary solvent for removing solvent comprises deionized water, hydrogen peroxide, methanol, ethanol, phentanol, and one or the compound selected from PGMEA. A removal method comprises the step of introducing the secondary solvent which acts as hydrogen donor to coal extract and removes sulfide compound within coal extract obtained from the coal extracting process of low class in a form of hydrogen sulfide gas. The secondary solvent is also used with one selected from reforming catalyst of metal oxide, metal hydroxide, activated charcoal, and transition metal or desulfurizing agent composed of the mixture. The desulfurizing agent is Ni group reforming catalyst.

PURPOSE: A manufacturing method for a metal- or metal oxide-supported catalyst using a melt-infiltration process with a metal hydrate salt and a metal- or metal oxide-supported catalyst thereof are provided to easily and quickly mass produce the metal- or metal oxide-supported catalyst by using a nitrate hydrate metal salt or a chloride hydrate metal salt with a low melting point. CONSTITUTION: A manufacturing method for a metal- or metal oxide-supported catalyst using a melt-infiltration process with a metal hydrate salt comprises the following steps: The metal hydrate salt is mixed with a metal substrate with a porous structure. After the mixing process, the mixture is melted at the melting point of the metal hydrate salt such that the metal hydrate salt infiltrates into the substrate. The metal hydrate salt infiltrated in the supporter is plasticized at a high temperature and chagrined to nanoparticles. The metal hydrate salt has a melting point within 35 - 120 deg. C.
