A Study on the Process Improvement of RJ-4 fuel Preparation using a Heteropoly Acid Catalyst

Heteropoly acid촉매를 이용한 RJ-4연료의 제조공정 개선연구

The study on the improvement of manufacturing process of RJ-4 liquid fuel that have high flash point, was carried out. In preparing of RJ-4 using commercially available MCPD, 1st, 2nd hydrogenation and isomerization reaction were enabled 1 step continuous process by combined use of heteropoly phosphoroustungstic cesium salt catalyst and 2nd stage-heat-controllable reactor. Also when heteropolyacid cesium salt was used as a isomerization catalyst instead of aluminum chloride, formation rate of exe-THDMCPD was higher, the catalyst could be easily separable from product and there was no production of waste acid, so this new reaction condition was confirmed as the environment friendly process.

인화점이 높은 합성 액체연료인 RJ-4의 제조공정 개선에 관한 연구를 수행하였다. 상용원료인 MCPD(Methylcyclopentadiene dimer)를 이용한 RJ-4 연료제조에서 헤테로폴리 텅스토인산 세슘염 촉매와 2단 열 조절반응기를 사용하여 1차, 2차 수소화 및 이성화반응이 1 단계 연속공정으로 가능함을 알 수 있었다. 또한 $AlCl_3$ 대신에 헤테로폴리산 세슘염을 이성화촉매로 사용시 exe-THDMCPD(Tetrahydrodimethylcyclopentadiene)을 얻는 속도가 더 빠르며, 생성물과의 분리가 용이하고, 폐산 발생이 없으므로 환경친화적인 공정임을 확인하였다.
