Abstract

탄화수소의 크래킹 동안 코크스(coke) 형성을 방지하도록 방오제로 처리된 열분해 크래킹 관의 유효성을 유지하기 위한 방법. 이러한 처리의 이점은 처리된 열분해 크래킹 관에 채우기 전에 황-함유 공급원료를 탈황함으로써 강화된다.

Description

크래킹 관 상의 코크스 형성을 방지하기 위한 탄화수소의 열 크래킹 방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (5)

  1. 탈황 탄화수소 공급물을 크래킹 조건하에서 작동되며, 코크스 형성을 방지하기 위해 공급물과 접촉하는 표면에 주석 및 실리콘이 침착되어 있는 처리된 크래킹 관으로 통과시키는 것을 포함하는 탄화수소의 열 크래킹 방법.
  2. 청구항 1에 있어서, 탈황 탄화수소 공급물이 약 50ppmm 이하의 황 농도를 갖는 방법.
  3. 청구항 1 또는 2에 있어서, 탈황 탄화수소 공급물의 크래킹 동안 처리된 크래킹 관내의 코크스 형성 속도가 1-탈황 탄화수소 공급물의 크래킹 동안 처리된 크래킹 관내의 코크스 형성 속도보다 작은 방법.
  4. 청구항 3에 있어서, 비-탈황 탄화수소 공급물이 약 50ppmm 이상의 황 농도를 갖는 방법.
  5. 청구항 1 또는 2에 있어서, 탈황 탄화수소 공급물을 제공하기 위해 황의 적어도 일부를 제거하기 위하여 황을 함유하는 탄화수소 공급물을 탈황하는 것을 포함하는 방법.
