A process for producing para-xylene and ethylbenzene from Caromatics containing ethylbenzene includes the steps of sending Caromatics containing ethylbenzene to an ethylbenzene liquid-phase adsorption separation device, wherein a suction liquid containing ethylbenzene and a suction residual liquid are obtained after the adsorption separation, and the desorbents in the suction liquid and the suction residual liquid are removed to obtain ethylbenzene and a suction residual oil; sending the suction residual oil to a para-xylene adsorption separation device, and unadsorbed components are discharged as a raffinate from the adsorbent bed; the adsorbent bed is rinsed with a desorbent to desorb the para-xylene therein and obtain an extract; the desorbents in the extract and the raffinate are respectively removed to obtain para-xylene and a raffinate oil; sending the raffinate oil to a xylene isomerization device to carry out xylene isomerization, and the isomerization product is fractionated.

A method for constructing a real-geographic-space scene in real time based on a panoramic-video technique is provided. By using a measuring robot and the attitude sensors, accurately determining the geographic coordinates and the attitudes of the cameras, where the cameras may be installed in a fixed or stringing manner, where in the fixing type a plurality of neighboring videos at the same moment undergo orthographic correction and splicing, and in the stringing type the cameras are installed to a guiding device and may locally, independently and quickly move and shoot, and the videos of the neighboring cameras are spliced in real time; and fusing the videos, the geographic coordinates and the environment sounds that satisfy the delay time, to form a scene video streaming.
