Application of activated clay to removal of silicon in naphtha

The invention discloses application of activated clay to removal of silicon in naphtha. The activated clay is continuously percolated by naphtha under the conditions that the temperature is 20-40 DEG C and the percolation pressure difference is not greater than 200kPa; according to the method, silicon in the high-silicon-content naphtha (the silicon content reaches 150ppm) is removed by adopting the activated clay, so that the method has a relatively high removal rate (the removal rate can reach 97%) and a relatively low sulfur content (the sulfur content can be reduced to 5ppm or below); the naphtha refining tower has the advantages that the naphtha refining tower is simple in structure and low in cost, the desiliconization cost is reduced (the service life is long) under the condition that other performances of naphtha are not influenced, the naphtha treatment capacity is large (the treatment capacity of 2.2 t/h can be achieved in a small refining tower in the embodiment 6), and safe and proper large-scale
