Patent ID: 8106250

Claim:
Process for removing silicon compounds from hydrocarbon streams by means of adsorption, characterized in that the process comprises the following stages: a) activation of the adsorbent, initially mixture of oxides of divalent and trivalent metals to form a lamellar double hydroxide by addition of H 2 O and CO 2 at a temperature from 80° C. to 360° C.; b) contact of the hydrocarbon feed with the adsorbent at a temperature from 80° C. to 360° C., at a pressure in the range from 0.5 to 5.0 MPa g maintained for H 2 /feed ratio from 10 to 1000 Nm 3 of gas/m 3 of feed, and space velocity LHSV from 1 to 20 h −1 ; c) maintaining said adsorbent in the condition of lamellar mixed hydroxide, by continuous addition of H 2 O, the water flow rate being from 0.01% to 100%, of the volume of the hydrocarbon feed being processed; d) recovery of the hydrocarbon stream free from Si compounds; where the composition of said adsorbent comprises a mixture of: (I)—lamellar double hydroxide; (II)—group VI-B or group VIII metal.
