Problems solved by technology

In this method, the γ-Al2O3 carrier is immersed in a solution containing Ni, and then dried and roasted, which will cause uneven dispersion of the active components on the carrier, and even agglomeration, which will affect the activity of the catalyst.
[0011] Through extensive and in-depth research on petroleum resin hydrogenation catalysts, it is found that the nickel-based catalysts prepared by existing methods have low catalytic activity and poor resistance to impurities (especially sulfur impurities), thereby affecting their stability.

Embodiment 1

[0020] Configure nickel chloride solution A, where Ni 2+ The ion concentration is 1mol / L respectively. 19.01g copper nitrate trihydrate (Cu(NO 3 ) 2 ·3H 2 O), 14.47g ferric nitrate trihydrate (FeN 3 o 9 9H 2 O), 0.31g lanthanum nitrate (LaN 3 o 9 ·6H 2 O) Add deionized water to dissolve and configure solution B. The carrier silica is added to solution B and stirred vigorously to obtain a slurry containing insoluble compounds, and then the slurry is spray-dried by air flow to obtain a catalyst precursor. Then impregnate the catalyst precursor with nickel chloride solution A, 120 o C drying, repeated several times, until the solid powder with the required nickel load is achieved. 500 o C was calcined for 10 h to obtain the finished catalyst.

Abstract

The invention relates to a nickel hydrogenation catalyst with large pore volume and high sulfur resistance and a preparation method thereof. The catalyst component comprises nickel, a porous carrier and an auxiliary agent. The invention also relates to a hydrogenation method for a sulfur-containing compound. According to the nickel hydrogenation catalyst prepared by the method, the specific pore volume of the catalyst is at least 0.5 ml / g, and the obtained catalyst is uniform in active component distribution and not easy to lose and pulverize. When the catalyst is used in the hydrogenation process of sulfur-containing compounds, high catalytic activity and stability are shown, the sulfur resistance is high, and the service life is long.

Description

technical field [0001] The invention relates to a nickel hydrogenation catalyst with large pore volume and high sulfur resistance, and relates to a method for preparing the catalyst and a method for hydrogenation refining of raw materials. The technology provides a preparation process and an application method of a catalyst exhibiting excellent sulfur tolerance, and belongs to the field of catalytic technology. Background technique [0002] At present, petroleum resin is mainly produced through petroleum cracking in industry, and there are a large number of sulfur-containing organic compounds in petroleum. Therefore, it is inevitable to contain a large amount of sulfur-containing organic compounds in the production process of the resin. Although through desulfurization process such as catalytic oxidation desulfurization, catalytic hydrodesulfurization, adsorption desulfurization and other desulfurization treatment. However, generally speaking, the sulfur content in raw mat...
