Problems solved by technology

[0007] Although the addition of shape-selective molecular sieves in the above two methods is beneficial to isomerization to increase the octane number of gasoline, the adsorbent lacks sufficient desulfurization activity due to the lack of suitable content of accelerator metals and sulfur storage media.

Embodiment 1

[0042] 4.43 kilograms of zinc oxide powder (Headhorse company, purity 99.7wt.%), 1.00 kilograms of SAPO-31 (Qilu Catalyst Branch Company, containing 0.70 kilograms on a dry basis) and 4.57 kilograms of deionized water were mixed, and after stirring for 30 minutes, zinc oxide and SAPO-31 mixed slurry.

[0043] Take 1.37 kg of alumina (produced by Shandong Aluminum Factory, containing 1.00 kg on a dry basis) and 2.10 kg of expanded perlite (including 2.06 kg on a dry basis) and mix them under stirring, then add 4.6 kg of deionized water and mix well, then add 360 ml 30wt.% hydrochloric acid (chemically pure, produced by Beijing Chemical Plant) was stirred and acidified for 1 hour, then heated to 80° C. for 2 hours, and then added with zinc oxide slurry and mixed for 1 hour to obtain carrier slurry.

[0044] The carrier slurry uses Niro Bowen Nozzle Tower TM The model spray dryer is used for spray drying, the spray drying pressure is 8.5 to 9.5MPa, the inlet temperature is below...

Embodiment 2

[0048] Get 1.61 kilograms of pseudo-boehmite (produced by Shandong Aluminum Plant, containing 1.17 kilograms on a dry basis) and 1.54 kilograms of diatomite (containing 1.50 kilograms on a dry basis) and mix under stirring, then add 8.2 kilograms of deionized water and mix well, Add 260 milliliters of 30% hydrochloric acid (chemically pure, produced by Beijing Chemical Factory) and stir for acidification for 1 hour, then raise the temperature to 80° C. and age for 2 hours. After the temperature dropped, 5.52 kg of zinc oxide powder (Headhorse Company, purity 99.7%) and 0.43 kg of SAPO-31 (Qilu Catalyst Branch, containing 0.30 kg on a dry basis) were added and stirred for 1 hour to obtain a carrier slurry.

[0049] Referring to the method of Example 1, the carrier was spray-dried and molded and the active component nickel was introduced to obtain the adsorbent A2. The chemical composition of adsorbent A2 is: zinc oxide content is 55.2wt.%, alumina binder content is 11.7wt.%, di...

Embodiment 3

[0051] The adsorbent was prepared as follows: 4.93 kg of zinc oxide powder (Headhorse Company, purity 99.7%), 0.71 kg of SAPO-34 (Qilu Catalyst Branch, 0.50 kg on a dry basis) and 5.57 kg of deionized water were mixed and stirred for 30 minutes Finally, a mixed slurry of zinc oxide and SAPO-31 is obtained.

[0052] Take 1.85 kg of pseudo-boehmite (produced by Shandong Aluminum Plant, containing 1.35 kg on a dry basis) and 1.64 kg of de-diatomite (world mining company, containing 1.60 kg on a dry basis) and mix them under stirring, then add 4.6 kg of deionized water After the kilogram is mixed evenly, add 300 milliliters of 30% hydrochloric acid (chemically pure, produced by Beijing Chemical Factory) to make the slurry pH value 2.5, stir and acidify for 1 hour, then heat up to 80° C. and age for 2 hours. Zinc oxide slurry was added and stirred for 1 hour to obtain carrier slurry.

[0053] Referring to the method of Example 1, the spray drying of the carrier was carried out and...

Abstract

The invention provides a hydrocarbon oil desulfurization adsorbent, a preparation method and an application method of the adsorbent. The adsorbent provided by the present invention, based on the total weight of the adsorbent, at least includes the following composition: 1) SAPO molecular sieve, with a content of 1-20wt%; 2) alumina binder, with a content of 3-35wt%; 3) oxidation 5-40wt% silicon source; 4) zinc oxide, 10-80wt% content; 5) at least one metal promoter selected from cobalt, nickel, iron and manganese, 5-30wt% content. The adsorbent of the invention has high desulfurization activity, and also has the advantage of obviously increasing the gasoline octane number.

Description

technical field [0001] The invention relates to an adsorbent for removing sulfur from hydrocarbon oil, a preparation method and application thereof. Background technique [0002] CN 1355727A provides a novel absorbent composition containing zinc oxide, silicon oxide, aluminum oxide and nickel or cobalt, and provides the preparation method of this adsorbent. In this method, a carrier containing zinc oxide, silicon oxide and aluminum oxide is prepared first, and then nickel is introduced by impregnation. The adsorbent can be used to remove sulfur from cracked gasoline or diesel fuel. [0003] In CN 1208124C, a promoter metal such as cobalt and nickel is used to impregnate an adsorbent carrier containing zinc oxide, expanded perlite and alumina, and then reduce the promoter at a suitable temperature to prepare an adsorbent for removing sulfide in cracked gasoline. [0004] When the above-mentioned adsorbent removes sulfur from gasoline under hydrogen-facing conditions, the oc...
