Abstract: PURPOSE: A catalyst for Fischer-Tropsch synthesis is provided to function as the fixed bed catalyst of both an ordinary fixed bed reactor and a multichannel reactor which generates reactions at a high space velocity. CONSTITUTION: A catalyst with a dual particle structure includes center particles and an outer particle layer(2). The center particles are made of heat transferring materials(1). The heat transferring materials are selected from a group including metals, metal oxides, ceramics, and a mixture of the same. The outer particle layer surrounds the center particles and is attached to the surface of the center particles by a binder material layer(3). The outer particle layer is composed of a support and powdered catalyst particles containing metal particles. The powdered catalyst particles are supported on the support. The heat transferring materials are selected from a group including SiC, alumina, alundum, silica, aluminum, stainless steel, copper, and a mixture of the same. The support is selected from a group including alumina, silica, zirconia, titania, and a mixture of the same.

Abstract: 본 발명은 피셔-트롭쉬 합성용 슬러리 반응에 의한 액체 탄화수소 화합물의 제조방법에 관한 것으로서, 더욱 상세하게는 합성가스로부터 촉매를 이용한 피셔-트롭쉬(Fischer-Tropsch; FT) 합성용 슬러리 반응을 수행하는 경우에 반응 중에 탄소수 7~12개의 고비점 알코올을 슬러리 반응매체의 첨가제로 사용하거나 FT 반응에서 생성되는 부산물로부터 분리된 상기 고비점 알코올을 재순환시켜 사용함으로써, 촉매의 뭉침 현상(catalyst clogging)에 의한 FT 반응활성 저하를 억제할 수 있음과 동시에 C5+ 이상의 탄화수소로의 선택성을 향상할 수 있게 되어 카본 활용 면에서 효율적인 피셔-트롭쉬 합성용 슬러리 반응에 의한 액체 탄화수소 화합물의 제조방법에 관한 것이다.

Abstract: PURPOSE: A preparing method of a liquid hydrocarbon compound by a slurry reaction for a fischer-tropsch synthesis is provided to prevent agglomeration of a catalyst in a slurry reactor, and to improve a F-T synthesis reactive catalyst for more stable GTL process. CONSTITUTION: A preparing method of a liquid hydrocarbon compound by a slurry reaction for a fischer-tropsch synthesis is performed under the presence of high-boiling point alcohol of 7~12 carbon numbers. The high-boiling point alcohol is re-purified by being divided from a by-product produced from the F-T synthesis. The boiling point of the high-boiling point alcohol is over 150 deg C. The concentration of the of the high-boiling point alcohol is 5,000~50,000 parts per million.
