Embodiment 1

[0021] 230g pseudo-boehmite (dry basis 70%) and 15g alumina powder are mixed with 12.1g carbon black, 1.55g phosphoric acid, 3.6g acetic acid, 7.2g squash powder, 211g clean water to become plastic, and then Extruded into 1.2mm four-leaf clover strips on an extruder, dried at 120°C for 4 hours, and calcined at 850°C for 2 hours to obtain carrier A, whose properties are listed in Table 1.

Embodiment 2

[0023] Mix and knead 230g pseudo-boehmite dry rubber powder and 28.4g alumina powder with 10.1g carbon black, 1.82g phosphoric acid, 4.0g formic acid, 7.6g starch, and 220g clean water to form a plastic body, and then extrude it on the extruder into 1.2mm four-leaf clover strips, dried at 120°C for 4 hours, and calcined at 950°C for 2 hours to obtain carrier B, whose properties are listed in Table 1.

Embodiment 3

[0025] In Example 1, the phosphoric acid was changed to boric acid, the acetic acid was changed to nitric acid, and the turnip powder was changed from 7.2 g to 11.8 g, which is the cost example, and the carrier C was obtained, and its properties are shown in Table 1.

Abstract

The present invention relates to a heavy oil hydrogenation treatment catalyst carrier and its preparation method. In the course of preparation the pseudo-thin empholite and aluminium oxide are mixed according to a certain proportion,then mixed with compound pore-expanding agent and kneaded to mouldable body, then strip-extruded and formed by means of strip-extruding machine, then dried and roasted at high temp. so as to obtain the required carrier.

Description

technical field [0001] The invention relates to a heavy oil hydrotreating catalyst carrier and a preparation method thereof, in particular to a residue oil hydrodemetallization and hydrodesulfurization catalyst carrier and a preparation method thereof. Background technique [0002] At present, industrial hydrotreating catalysts are usually supported by alumina or alumina containing a small amount of additives, and metal elements of group VIII and group VIB are used as active components. It is well known that the pore structure of the catalyst has an important influence on the performance of the catalyst. Catalysts for heavy oil hydrotreating, especially catalysts used for residual oil hydrotreating, generally need to have larger pore diameter and pore volume to facilitate the internal diffusion of macromolecular reactants in heavy oil and avoid or slow down the The deposition of the catalyst blocks the pores of the catalyst, resulting in a rapid decline in catalyst activity...
