Abstract
"PROCESSO DE HIDRODESSULFURIZAçãO SELETIVA DE NAFTA". é descrito um processo de hidrodessulfurização seletiva de nafta contendo olefinas e compostos organossulfurados, que minimiza a hidrogenação de olefinas e resulta em um produto com teor reduzido de enxofre, o que é conseguido por hidrodessulfurização em dois estágios e remoção de H~ 2~S do efluente do primeiro estágio. Uma corrente de hidrogênio e pelo menos um composto não-reativo adicionado é alimentada no primeiro estágio, sendo a fração molar de H~ 2~ compreendida em uma faixa de 0,2 a 1,0 e limitando H~ 2~S na entrada do reator a não mais que 0,1% em volume. No segundo estágio é alimentada uma corrente de hidrogênio e pelo menos um composto não-reativo adicionado, sendo a fração molar de H~ 2~ compreendida em uma faixa de 0,2 a 0,7 e limitando H~ 2~S na entrada do reator a não mais que 0,05% em volume."SELECTED NAFTA HYDRODULFURIZATION PROCESS". A selective naphtha hydrodesulphurization process containing olefins and organosulphurous compounds is described which minimizes the olefin hydrogenation and results in a reduced sulfur product, which is achieved by two-stage hydrodesulphurization and removal of H ~ 2 ~ S from the product. effluent from the first stage. A hydrogen stream and at least one non-reactive compound added are fed in the first stage, the molar fraction of H ~ 2 ~ being in the range of 0.2 to 1.0 and limiting H ~ 2 ~ S at the inlet of the hydrogen. reactor to not more than 0,1% by volume. In the second stage a hydrogen stream and at least one non-reactive compound are added, the molar fraction of H ~ 2 ~ within a range of 0.2 to 0.7 and limiting H ~ 2 ~ S at the input of the hydrogen. reactor to not more than 0,05% by volume.
