Embodiment I

[0097] The reduced nickel metal solid sorbent was produced as follows: 20.02 lbs of diatomaceous earth silica and 25.03 lbs of zinc oxide were dry blended in a grinder for 15 minutes to produce a first mixture. While still mixing, a solution containing 6.38 lb Dispersal alumina (Condea), 22.5 lb deionized water, and 316 g glacial acetic acid was added to the mill to produce a second mixture. Mixing was continued for 30 minutes after addition of these components was complete. The second mixture was then dried at 300°F for 1 hour and fired at 1175°F for 1 hour to form a third mixture. The third mixture was then granulated using a Stokes Pennwalt granulator equipped with a 50 mesh screen. The resulting granulated mixture was then impregnated with 673.8 g of nickel nitrate hexahydrate per 454 g of the granulated third mixture dissolved in 20 g of hot (200°F) deionized water to produce impregnated granules. The impregnated particles were dried at 300°F for 1 hour and calcined at...

Embodiment II

[0101] The desulfurization ability of the reduced nickel solid particle adsorbent prepared in Example I was tested as follows.

[0102] A lin quartz tube reactor was charged with the adsorbent of Example I in the amounts indicated below. The reduced nickel solid sorbent was placed on a frit in the middle of the reactor and reduced with hydrogen as described in Example 1. A gaseous cracked gasoline containing about 310 ppm sulfur (parts by weight of sulfur compounds based on the weight of the gaseous cracked gasoline) and about 95 ppm sulfur based on the weight of the gaseous cracked gasoline was pumped upward through the reactor. % by weight thiophenes (eg, alkylbenzothiophenes, alkylthiophenes, benzothiophenes, and thiophenes). The flow rate is 13.4ml / hr. Produces sulfurized solid sorbent and desulfurized gaseous cracked gasoline. In Test 1, no hydrogen was used in the desulfurization process, resulting in no reduction in the sulfur content.

[0103] After Run 1, the sulf...

Embodiment III

[0115] A second reduced nickel metal solid sorbent composition was prepared as follows:

[0116] 363g of diatomaceous earth silica was mixed with 443g of Nyacol Al-20 alumina in a grinder. While still continuing to mix, 454 g of zinc oxide dry powder was added to the above mixture, and mixed for another 30 minutes to form an extrudable paste. The paste was extruded through a laboratory 1-in Bonnot extruder equipped with a die with a 1 / 16 in hole. The wet extrudate was dried at 300°F for 1 hour and fired at 1175°F for 1 hour. 500 g of the dry extrudate were then impregnated with a solution of 371.4 g of nickel nitrate hexahydrate dissolved in 36.5 ml of deionized water. The nickel impregnate was dried at 300°F for 1 hour and fired at 1175°F for 1 hour. 200 g of the first nickel impregnated sorbent were impregnated a second time with 74.3 g of nickel nitrate hexahydrate dissolved in 30 g of deionized water. After the second impregnation, the impregnated extrudates were dried...

Abstract

Particulate sorbent compositions comprising a mixture of zinc oxide, silica, alumina and a substantially reduced valence nickel are provided for the desulfurization of a feedstream of cracked-gasoline or diesel fuels in a desulfurization zone by a process which comprises the contacting of such feedstreams in a desulfurization zone followed by separation of the resulting low sulfur-containing stream and sulfurized-sorbent and thereafter regenerating and activating the separated sorbent before recycle of same to the desulfurization zone.

Description

field of invention [0001] This invention relates to the desulfurization of cracked gasoline and diesel fuel fluid streams. In another aspect, the invention relates to sorbent compositions suitable for desulfurization of cracked gasoline and diesel fuel fluid streams. In yet another aspect, the invention relates to a process for the production of sulfur sorbents for desulfurization from cracked gasoline and diesel fuel fluid streams. Background of the invention [0002] The need for cleaner fuels has led to ongoing worldwide efforts to reduce the sulfur content of gasoline and diesel fuel. Reducing the sulfur content of gasoline and diesel is considered one of the measures to improve air quality, because sulfur in the fuel has an adverse effect on the performance of automobile catalytic converters. The presence of sulfur oxides in automobile engine exhaust inhibits and can irreversibly poison noble metal catalysts in the converter. Exhaust gases from inefficient or poisone...
