In this study, surface-adsorbed species of 1,2-dichlorobenzene (1,2-DCB) on mesoporous $V_2O_5/TiO_2$ catalysts synthesized by spray pyrolysis were investigated through the adsorption/desorption performed using in situ FT-IR cell. Also, the comparison of adsorbed species with $TiO_2$ and $V_2O_5/TiO_2$ synthesized by the incipient wetness was carried out.

The objective of this study is to develop a platinum/hexaaluminate pellet catalyst for the decomposition of eco-friendly liquid propellant. Pellet catalysts using hexaaluminate prepared by ultrasonic spray pyrolysis as a support and platinum as an active metal were prepared by two methods. In the case of the pellet catalyst formed by loading the platinum precursor onto the hexaaluminate powder and then adding the binder (M1 method catalyst), the mesopores were well developed in the catalyst after calcination at 550 ℃. However, when this catalyst was calcined at 1,200 ℃, the mesopores almost collapsed and only a few macropores existed. On the other hand, in the case of a catalyst in which platinum was supported on pellets after the pellet was produced by extrusion of hexaaluminate (M2 method catalyst), the surface area and the mesopores were well maintained even after calcination at 1,200 ℃. Also, the catalyst prepared by the M2 method showed better heat resistance in terms of platinum dispersion. The effects of preparation method and calcination temperature of Pt/hexaaluminate pellet catalysts on the decomposition of liquid propellant composed mainly of ammonium dinitramide (ADN) or hydroxyl ammonium nitrate (HAN) were investigated. It was confirmed that the decomposition onset temperature during the decomposition of ADN- or HAN- based liquid propellant could be reduced significantly by using Pt/hexaaluminate pellet catalysts. Especially, in the case of the catalyst prepared by the M2 method, the decomposition onset temperature did not show a large change even when the calcination temperature was raised at 1,200 ℃. Therefore, it was confirmed that Pt/ hexaaluminate pellet catalyst prepared by M2 method has heat resistance and potential as a catalyst for the decomposition of the eco-friendly liquid propellants. 본 연구의 목적은 친환경 액체 추진제 분해반응에 적용하기 위하여 백금이 담지된 헥사알루미네이트 펠렛 촉매를 개발하는것이다. 초음파 분무 열분해법으로 제조한 hexaaluminate를 지지체로 사용하고 백금을 활성금속으로 사용한 펠렛 촉매를 두가지 방법으로 제조하였다. 백금 전구체를 헥사알루미네이트 분말에 담지한 후에 바인더를 첨가하여 성형한 펠렛 촉매의경우(M1 method 촉매), 550 ℃에서 소성한 촉매는 메조기공이 잘 발달하였다. 그러나 이 촉매를 1,200 ℃에서 소성하면 메조기공이 거의 무너지고 약간의 거대기공만 존재하였다. 반면에, 헥사알루미네이트를 성형하여 펠렛을 제조한 후, 펠렛 위에백금을 담지한 촉매의 경우(M2 method 촉매), 1,200 ℃에서 소성한 후에도 표면적과 메조기공이 잘 유지되는 것으로 나타났다. 또한, 백금 분산도 측면에서도 M2 method로 제조한 촉매의 내열성이 더 우수하였다. 펠렛 촉매 제조 방법과 소성온도가ammonium dinitramide (ADN) 또는 hydroxyl ammonium nitrate (HAN)을 주성분으로 하는 액상 추진제의 분해반응에 미치는 영향을 분석하였다. ADN 기반 액체 추진제 및 HAN 기반 액체추진제의 분해반응에서 Pt/hexaaluminate 펠렛 촉매를 사용하면 분해 개시 온도를 큰 폭으로 내릴 수 있음을 확인하였다. 특히, M2 method로 제조한 촉매의 경우, 소성온도를 1,200 ℃로 올린 경우에도 분해 개시 온도가 큰 변화를 보이지 않았다. 따라서 M2 method로 제조한 Pt/hexaaluminate 펠렛 촉매가내열성을 보유하고 있으며, 친환경 액상 추진제의 분해 반응용 촉매로서 잠재력이 있다는 것을 확인하였다.

Objective: Personal mobility vehicles (PMV) have been used widely as a means of replacing bicycles in recent years because of their convenience and high economic efficiency. On the other hand, accidents related to PMV are also increasing, but there have been few studies in this area. This study examined the factors that increase the severity of damage and determine the characteristics of the PMV compared to the accidents on a bicycle. Methods: Retrospective observational studies were performed. The variables related to the accident were collected and analyzed for patients who visited the emergency room due to a PMV and bicycle accident. Multivariate logistic regression analysis was used to determine the factors affecting the severity of the patients. The odds ratios were calculated and compared between injuries related to PMV and bicycles. Results: A total of 1,124 patients (bicycles 1,017, PMV 107) were enrolled in this study. In multivariate regression analysis, the severity of PMV was higher (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.06-2.83) than that of a bicycle. The factors affecting the severity of the patients were age (OR, 1.02, 95% CI, 1.01-1.03), alcohol use (OR, 1,70; 95% CI, 1.04-2.70), ambulance transport (OR, 2.46; 95% CI, 1.78-3.40), and wearing a helmet (OR, 2.06; 95% CI, 1.36-3.13). Conclusion: PMV showed higher severity of damage than a bicycle. The PMV, which is a new transportation means, is insufficient for the prevention of safety compared to bicycles where driving regulations and wearing protective equipment are common. Additional studies on the precise mechanisms of injury and damage are expected to prevent accidents and reduce their severity.

부생가스 중 LDG, BFG, FOG 등에서는 CH4, H2, CO, CO2 등 다성분혼합물의 상태로 존재하며 일산화탄소를 대량으로 배출하여 지구온난화를 가중시키고 있다. 만일 경제적으로 일산화탄소를 분리회수할 수 있는 분리기술이 된다면 탄소자원화의 원료를 값싸고 공급할 수 있다. 본 실험에서는 부생가스내에 일산화탄소를 분리 회수하는 분리막 정제 시스템 개발을 위한 연구를 수행하였다. 분리막 공정 설계에 필요한 데이터를 확보하기 위하여 분리막 모듈의 이산화탄소, 일산화탄소, 질소, 메탄 등을 대상으로 기체들의 조성, 공급온도 및 공급압력, 스테이지컷 등의 운전조건을 고려하여 분리실험을 수행하였다. 실험한 결과를 바탕으로 공정 설계 인자에 따른 공정설계 시뮬레이션을 구성하였으며, 막분리 공정 설계 시뮬레이션 결과 및 실험결과를 비교 분석하였다.
