Abstract
Description
상기 기술된 개선안에도 불구하고, 지금까지 2 내지 8 주 또는 그 이상의 오랜 수행 시간은 필수적이었다. "수행 (running-up) 시간"은 촉매가 현재의 기술 수준에 따라 공기 표준 ㎥ (N㎥) 당 80 g 이상의 o-크실렌의 필요한 최종 적재량을 달성하는, 즉 촉매가 비가역적으로 손상되지 않고 정상 상태로 산화되는데 필요한 시간을 말한다. 여기서, 특히 주의할 점은 열점이 특정 임계값 (통상적으로 450 내지 480 ℃)을 초과하지 않도록 보장되어야 하는데, 그렇지 않으면 PA 선택성, PA 생성물의 품질 및 촉매의 수명이 매우 불리한 영향을 받을 수 있기 때문이다.
실시예 : 촉매 조합 | 염조 온도 (℃) | 수행 시간 | 30 일 동안 평균 PA 수율 (중량%) | 30 일 동안 조 PA 중의 프탈리드 평균 함량 (몰%) |
8: I(a), IV(b), VII (c) | 380-370 | 7 | 111.5 | 0.10-0.19 |
9: II(a), V(b), VII (c) | 370-366 | 10 | 113 | 0.15-0.25 |
10: 비교 IV(b)/VII(c) | 365-355 | 32 | 112.5 | 0.05-0.22 |
11: 비교 I(a)/VII(c) | 380-370 | 10 | 113 | 0.37-0.58 |
12: 비교 IV(b) + 스테아타이트/VII(c) | 375-365 | 11 | 113 | 0.33-0.55 |
13: 비교 III/VI/VIIc | 380-370 | 적재량는 지속 시간 동안 공기 N㎥ 당 약 40 g 이상의 o-크실렌 값으로 증가될 수 없다 | (수행 시간 아래의 설명 참조) | (수행 시간 아래의 설명 참조) |
실시예: 촉매 조합 | 염조 온도 | 수행 시간 | 30 일에 걸친 평균 PA 수득량 | 30 일에 걸친 조제 중의 평균 프탈리드 함량 (몰%) |
14: I(a)/IV(b)/VII(c) | 375 | 13 | 110 | 0.14-0.19 |
15: II(a), V(b), VII (c) | 366 | 15 | 111.5 | 0.14-0.24 |
16: 비교 IV(b)/VII(c) | 356-353 | 적재량는 지속 시간 동안 공기 N㎥ 당 약 90 g의 o-크실렌 값으로 증가될 수 없다 | ("수행 시간"아래의 설명 참조) | ("수행 시간"아래의 설명 참조) |
17: 비교 I(a)/VII(c) | 370-366 | 적재량는 목적하는 공기 N㎥ 당 약 105 g의 o-크실렌 값으로 증가될 수 있지만, 폐기 기체 중의 프탈리드의 높은 값과 크실렌의 상당량, 0.1 내지 0.2%가 N㎥ 당 90 g 이상의 적재량에서 관측된다. | ("수행 시간"아래의 설명 참조) | ("수행 시간"아래의 설명 참조) |
