Abstract:
본 발명은 유용성(Oil-soluble) 몰리브데늄 계열 이금속 촉매의 제조방법 및 이를 이용한 중질유의 수소화 전환방법에 관한 것으로, 높은 비점의 중질유(重質油)를 낮은 비점의 경질유(輕質油)로 전환시키기 위하여 유용성 몰리브데늄 계열 이금속 촉매를 제조하고 중질유을 촉매 수소화 전환하는 방법에 관한 것이다. 이를 위하여 유용성으로 제조가 어려운 몰리브데늄 이금속 촉매를 수산화물 전구체를 경유하여 제조함으로써 금속들의 비율 조정 및 제조가 용이하도록 하며, 중질유의 수소화 전환반응 시 유용성 촉매를 사용함에 따라 분산효과가 뛰어나 수소화 전환반응에서 소량의 촉매만을 사용하여도 우수한 반응 효과를 기대할 수 있도록 하는 것이다.
Abstract:
본 발명은 2가지 이상의 금속이 결합된 수산화물 계열 전구체의 표면 개질을 통한 유용성(Oil-Soluble) 입자 제조방법에 관한 것이다. 더욱 상세하게는 서로 다른 금속들의 결합으로 이루어진 유용성 입자를 제조하는 것으로, 서로 다른 금속염들을 유기산들과 동시에 혼합하여 유용성 입자로 제조하는 대신에 금속들의 비율 조정 및 제조가 용이한 수산화물 계열 전구체들을 먼저 제조한 후에 유기산들과의 반응을 유도하여 유용성 입자로 제조하는 것을 특징으로 한다.
Abstract:
The present invention relates to an indirect gasifier with a dual bubbling fluidized bed. The indirect gasifier comprises: a first bubbling fluidized bed reactor (100) including a gasification area (110) in which materials to be gasified are fed and gasified to be discharged as a synthetic gas; and a second bubbling fluidized bed reactor (200) that is installed adjacent to the first bubbling fluidized bed reactor (100) with a wall (300) therebetween and includes a combustion area (210) in which materials to be combusted are fed and combusted to be discharged as a combusted gas. A fluid sand transferring device (400) is installed on the wall (300) so as to move the gasification area (110) and combustion area (210), so that heat that is generated during combustion in the combustion area (210) is transferred to the gasification area (110). According to the configuration of the present invention, fluid sand is circulated by being horizontally moved in two bubbling fluidized bed reaction areas so that heat that is generated during combustion is transferred to the gasification area (110) and raw materials, which are fed in the indirect gasifier, are gasified. Fluid sand can be horizontally circulated so that the indirect gasifier can be stably and easily operated.

PURPOSE: A method for preparing oil-soluble particles is provided to obtain the oil-soluble particles based on various metal by inducing the reaction with organic acid after a hydroxide-based precursor is prepared. CONSTITUTION: Two or more metal compound aqueous solutions are mixed and stirred(S11). The pH of the mixed aqueous solution is controlled between 5.0 and 10.0 in order to cause coprecipitation. Precipitate is collected through the coprecipitation(S12). A hydroxide-based precursor combined with two or more metal is prepared. The surface of the hydroxide-based precursor is modified using organic acid through an esterification reaction. The organic acid is one selected from a group including aliphatic acid, alicyclic acid, aromatic acid, phosphorus-containing acid.

Abstract:
A fuel oil-refining apparatus is provided to remove chloride components contained in fuel oil, which is obtained by treating waste plastic or waste oil, thereby producing high-quality fuel oil without chloride components. A chemical refinement unit(60) mixes low-quality fuel oil and basic aqueous solution, wherein the low-quality fuel oil is prepared by pyrolyzing and distilling one component selected from waste plastic, waste synthetic resin, waste rubber, or waste oil. A water-oil separator(70) separates fuel oil from the mixture of the fuel oil and the basic aqueous solution. A horizontal partition wall(730) is disposed in the middle of the water-oil separator to divide an inside space of the water-oil separator into a first space(710) and a second space(720). Upper portions of the first space and the second space communicate with each other. Further, a fuel oil-refining apparatus(200) additionally contains a water-oil mixer(80) at an upper part of the chemical refinement unit.
