Изобретение относитс  к нефтеперерабатывающей , нефтехимической и химической промышленности, в частности, к приготовлению активных и селективных сорбентов дл  адсорбционной очистки различных нефтепродуктов.The invention relates to the refining, petrochemical and chemical industries, in particular, to the preparation of active and selective sorbents for the adsorption purification of various petroleum products.

Известны различные способы активации природных сорбентов (например, бентонитовых глин, полыгорскитов, диатомитов). В последние годы примен етс  новый эффективный метод активации природных сорбентов - известкование 1.There are various ways to activate natural sorbents (for example, bentonite clays, polyhorskites, diatomites). In recent years, a new efficient method for the activation of natural sorbents, liming 1, has been applied.

Однако по известному способу известкование проводитс  многократной обработкой сорбента насыщенным раствором извести при периодическом перемешивании, отстаивании и замене отработанного раствора свежим.However, according to a known method, liming is carried out by repeatedly processing the sorbent with a saturated solution of lime with occasional stirring, settling and replacing the spent solution with fresh.

Цель изобретени  - сокращение продолжительности активации.The purpose of the invention is to reduce the duration of activation.

Дл  этого обработку суспензии сорбента провод т в ультразвуковом поле. Частота излучени  ультразвука составл ет 22 кГц.For this, the processing of the sorbent suspension is carried out in an ultrasonic field. The ultrasound frequency of the ultrasound is 22 kHz.

Пример. Активи ацию природного сорбента , предварительно прокаленного при 500°С в течение 3 ч., провод т насыщеннымExample. The activation of the natural sorbent, pre-calcined at 500 ° C for 3 hours, is carried out saturated

раствором извести в соотношении твердое к жидкому 1:20, в ультразвуковом поле на УЗДН-1. Режим обработки на приборе: частота 22 кГц, ток подмагничивани  6 А ток интенсивности 0,57 А, врем  40 мин.a solution of lime in the ratio of solid to liquid 1:20, in the ultrasonic field on UZDN-1. The processing mode on the device: frequency 22 kHz, bias current 6 A, intensity current 0.57 A, time 40 min.

После активации природный сорбент промывают водой до нейтральной реакции по фенолфталеину и сушат при 170°С в течение 6 ч.After activation, the natural sorbent is washed with water until neutral with phenolphthalein and dried at 170 ° C for 6 h.

Эффективность активации сорбента провер ют по изменению кислотности светлых нефтепродуктов (ГОСТ 14141-69) и адсорбции смол. Дл  этого в стекл нную колонку (d 2 см), загружают 6 г сорбента (фракци  0,25-0,5 мл) и пропускают светлый нефтепродукт или смолу.The efficiency of sorbent activation is checked by changing the acidity of light oil products (GOST 14141-69) and resin adsorption. To do this, a glass column (d 2 cm) was charged with 6 g of sorbent (0.25-0.5 ml fraction) and the light oil or resin was passed through.

Предлагаемый способ позволит избежать многократной обработки сорбента известью и сократить процесс обработки до 40 мин.The proposed method will allow to avoid repeated treatment of the sorbent with lime and reduce the processing process to 40 minutes.
