Targeted desulfurization process and apparatus integrating gas phase oxidative desulfurization and hydrodesulfurization to produce diesel fuel having an ultra-low level of organosulfur compounds

탄화수소 공급물의 탈황은 표적 차단점 온도에서 공급물을 플래시 처리하여 2개의 분획을 얻음으로써 성취된다. 제1 분획은 표적 차단점 온도 이상에서 비등하는 내화성 유기 황 화합물을 함유한다. 표적 차단점 온도 미만에서 비등하는 제2 분획은 내화성 황-함유 화합물을 실질적으로 포함하지 않는다. 제2 분획은 온화한 조건 하에 조작되는 수소화탈황 반응 구역에서 수소화탈황 촉매와 접촉하여 유기 황 화합물의 분량을 초저 수준으로 감소시킨다. 제1 분획은 기상 촉매 산화 반응 구역에서 화학식 Cu x Zn 1 - x Al 2 O 4 를 갖는 산화 촉매 위에서 가스 산화제와 접촉하여 내화성 유기 황 화합물을 내지 SO x 및 저황 탄화수소로 전환한다. 부산물 SO x 는 이후 제거되어, 감소된 수준의 유기 황 화합물을 함유하는 스트림을 제조한다. Desulfurization of the hydrocarbon feed is accomplished by flashing the feed at the target cutoff temperature to obtain two fractions. The first fraction contains refractory organic sulfur compounds boiling above the target cutoff temperature. The second fraction boiling below the target cutoff temperature is substantially free of refractory sulfur-containing compounds. The second fraction is brought into contact with the hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operated under mild conditions to reduce the amount of organic sulfur compounds to very low levels. The first fraction is contacted with a gas oxidant on an oxidation catalyst having the formula Cu x Zn 1 - x Al 2 O 4 in the gas phase catalytic oxidation zone to convert refractory organic sulfur compounds to SO x and low sulfur hydrocarbons. Byproduct SO x is then removed to produce a stream containing reduced levels of organic sulfur compounds.

Mild hydrodesulfurization integrating gas phase catalytic oxidation to produce fuels having an ultra-low level of organosulfur compounds

탄화수소공급물의 탈황은 처음에 전체 공급물을 온화한 조건 하에 조작되는 수소화탈황 반응 구역에서 수소화탈황 촉매와 접촉시켜 불안정 유기 황 화합물을 제거함으로써 성취된다. 수소화탈황 반응 구역의 플래시 처리 칼럼 다운스트림은 유출물을 표적 차단점 온도에서 분별화하여 2개의 탄화수소 연료 분획을 얻는다. 표적 차단점 온도 이상에서 비등하는 제1 분획은 남은 내화성 유기 황 화합물을 함유한다. 표적 차단점 온도 미만에서 비등하는 제2 분획은 유기 황 화합물을 실질적으로 포함하지 않는데, 왜냐하면 이 분획 범위에서 비등하는 유기 황 화합물은 온화한 수소화탈황에 의해 초기에 제거되는 불안정 유기 황 화합물이기 때문이다. 제1 분획은 기상 촉매 산화 반응 구역에서 화학식 Cu x Zn 1-x Al 2 O 4 를 갖는 산화 촉매 위에서 가스 산화제와 접촉하여 내화성 유기 황 화합물을 SO x 및 저황 탄화수소로 전환한다. 부산물 SO x 는 이후 제거되어, 감소된 수준의 유기 황 화합물을 함유하는 스트림을 제조한다. Desulfurization of the hydrocarbon feed is accomplished by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operated under mild conditions to remove unstable organic sulfur compounds. The flash treatment column downstream of the hydrodesulfurization zone fractionates the effluent at the target cutoff temperature to obtain two hydrocarbon fuel fractions. The first fraction boiling above the target cutoff temperature contains the remaining refractory organic sulfur compounds. The second fraction boiling below the target cutoff temperature is substantially free of organic sulfur compounds because the organic sulfur compounds boiling in this fraction range are unstable organic sulfur compounds that are initially removed by mild hydrodesulfurization. The first fraction is contacted with a gas oxidant on an oxidation catalyst having the formula Cu x Zn 1-x Al 2 O 4 in the gas phase catalytic oxidation zone to convert the refractory organic sulfur compounds into SO x and low sulfur hydrocarbons. By-product SO x is then removed to produce a stream containing reduced levels of organic sulfur compounds.
