    • The present invention discloses a process for producing olefins from petroleum saturated hydrocarbons. The process of the present invention comprises: contacting a preheated petroleum saturated hydrocarbons feedstock with a dehydrogenation catalyst in a dehydrogenation reaction zone of a reaction system to obtain a petroleum hydrocarbon stream containing unsaturated hydrocarbon compounds, in which the dehydrogenation reaction has a conversion rate of at least 20%; and contacting the obtained petroleum hydrocarbon stream containing the unsaturated hydrocarbon compounds with olefins cracking catalyst in an olefin cracking zone of the reaction system to obtain a product stream containing olefins with a reduced number of carbon atoms.
    • 本发明公开了一种从石油饱和烃生产烯烃的方法。 本发明的方法包括:使预热的石油饱和烃原料与脱氢催化剂在反应体系的脱氢反应区中接触,得到含有不饱和烃化合物的石油烃流,其中脱氢反应的转化率为 至少20%; 并将所得到的含有不饱和烃化合物的石油烃物流与烯烃裂化催化剂在反应体系的烯烃裂化区中接触,得到含有碳原子数减少的烯烃的产物流。

    • The invention relates to an ethylene cracking furnace having a multi-pass radiant coil, comprising at least one radiant section. In the radiant section there are provided with bottom burners and/or sidewall burners, and at least one set of multi-pass radiant coil longitudinally arranged in the radiant section. The multi-pass radiant coil is a four- to ten-pass type radiant coil. At least one tube of the multi-pass radiant coil is arranged to be spatially adjacent to a tube which is not consecutive to said at least one tube. With this arrangement, the thermal radiation influence between tubes with high temperature can be reduced, so that the tubes with low temperature can absorb the radiation heat from the tubes with high temperature. Therefore, the surface temperature of the tubes with high temperature can be reduced, thus extending the lifetime of the radiant coil and the operational cycle of the cracking furnace.
    • 本发明涉及具有多遍辐射线圈的乙烯裂解炉,其包括至少一个辐射段。 在辐射部分中,设置有底部燃烧器和/或侧壁燃烧器,以及纵向布置在辐射部分中的至少一组多通道辐射线圈。 多遍辐射线圈是四到十通的辐射线圈。 多通道辐射线圈的至少一个管被布置成在空间上与不与所述至少一个管连续的管相邻。 通过这种布置,可以降低具有高温的管之间的热辐射影响,使得具有低温的管可以高温地吸收来自管的辐射热。 因此,可以降低高温管的表面温度,从而延长辐射线圈的寿命和裂解炉的操作周期。
