    • A process for treating a light cracked naphtha (1) to be used as an etherification or alkylation feedstock in which the mercaptans and diolefins react in a single pass fixed bed reactor (20) and are removed in a distillation column reactor (10) which hydrogenate the unreacted diolefins. The mercaptans are reacted with the diolefins to form sulfides which are higher boiling than that portion of the naphtha which is used as feed to the etherification or alkylation unit. The higher boiling sulfides are removed as bottoms along with any C6 and heavier materials. Any diolefins not converted to sulfides are selectively hydrogenated to mono-olefins for use in the etherification process. Certain C5 olefins, for example pentene-1 and 3-methyl butene-1 are isomerized during the process to more beneficial isomers.
    • 一种用于处理轻度裂化石脑油(1)的方法,其用作醚化或烷基化原料,其中硫醇和二烯烃在单程固定床反应器(20)中反应,并在蒸馏塔反应器(10)中除去,氢气化 未反应的二烯烃。 硫醇与二烯烃反应形成沸点高于用作醚化或烷基化单元的进料的石脑油部分的硫化物。 较高沸点的硫化物作为底部以及任何C6和较重的材料被除去。 任何未转化成硫化物的二烯烃都被选择性氢化成单烯烃,用于醚化过程。 某些C5烯烃,例如戊烯-1和3-甲基丁烯-1在该过程中被异构化为更有益的异构体。

    • The aging rate of the catalyst in a process for the concurrent alkylation of aromatic with olefin and distillation of reaction components (reactants and products) in a distillation column reactor (10) in a catalyst bed (101) wherein the catalyst also serves as the distillation structure, is retarded by limiting the conversion of olefin in the catalyst bed to about 90 percent. A portion up to and including the entire unreacted aromatic and olefin in the overhead (3) from the distillation column reactor are condensed and fed to a fixed bed alkylation reactor (20) to substantially finish the conversion with a portion of the effluent from the fixed bed reactor (13) recycled thereto to control the olefin content in the fixed bed reactor inlet to less than one volume percent, preferably less than 0.50 volume percent and thereby reduce the aging in that catalyst. A fixed bed transalkylation reactor (30) is used to convert the polysubstituted alkylated aromatic products to mono-substituted alkylated aromatic products.

    • A catalytic cracked naphtha is desulfurized with minimum loss of olefins and octane. The naphtha is fed to a first distillation column reactor (10) which acts as a depentanizer or dehexanizer with the lighter material containing most of the olefins and mercaptans being boiled up into a first distillation reaction zone (11) where the mercaptans are reacted with diolefins to form sulfides which are removed in the bottoms along with any higher boiling sulfur compounds. The bottoms are subjected to hydrodesulfurization in a second distillation column reactor (20) where the sulfur compounds are converted to H2S and removed. The lighter fraction containing most of the olefins is thus not subjected to the more harsh hydrogenation conditions of the second reactor (20).
    • 催化裂化石脑油以最少的烯烃和辛烷值的损失脱硫。 将石脑油加入到第一蒸馏塔反应器(10)中,该反应器(10)充当脱苯胺或脱脂装置,其中较轻的材料含有大部分烯烃和硫醇被煮沸成第一蒸馏反应区(11),其中硫醇与二烯烃 以形成硫化物,其随着任何更高沸点的硫化合物在塔底中除去。 将塔底物在第二蒸馏塔反应器(20)中进行加氢脱硫,其中硫化合物转化为H 2 S并除去。 因此,含有大部分烯烃的轻馏分不会受到第二反应器(20)的更苛刻的氢化条件的影响。
