preparation example Construction

[0031] The invention discloses a preparation method of a diesel functional component. The preparation method comprises the following steps:

[0032] Step 1, pyrolyzing Jatropha japonica shell and oil meal to obtain carbonized product, then adding concentrated sulfuric acid and heating to obtain black solid;

[0033] Step 2, adding polyethylene solution to the black solid of step 1, drying and grinding to obtain component A;

[0034] Step 3, one or more of the group consisting of metal oxide, acidic substance and ammonium-containing compound are mixed and roasted to obtain component m;

[0035] Step 4, the α-Al 2 O 3 , one or more of the group consisting of acidic substances and ammonium-containing compounds are mixed and calcined to obtain component n; and

[0036] Step 5, mixing components m and n, then adding polyvinyl alcohol solution, roasting and grinding into powder to obtain component B, and mixing component B and component A obtained in step 2 to obtain a catalyst f...

Embodiment 1

[0052] Jatropha husk and oil meal were heated at 200 °C at a heating rate of 5 °C / min in N 2 Pyrolysis was carried out under air flow for 1 h to promote partial carbonization in situ. Add 200 mL of oleum to 20 g of carbonized product, in N 2 The mixture was heated from room temperature to 50°C under airflow. Foaming occurs during heating. After heating at 50 °C for 16 h, a black solid was obtained, excess sulfuric acid was removed, and the black solid was repeatedly washed with a large amount of distilled water at 25 °C until the filtrate was neutral and free of sulfate ions. After filtration, it was dried in an oven at 25°C overnight, ground into powder, added with 8% polyethylene solution by mass, dried in an oven at 85°C for 30 hours, and ground into fine particles to prepare component A; magnesium oxide and glacial acetic acid were mixed with Mixed with ammonium bicarbonate and calcined at 700℃ for 20min, α-Al 2 O 3 The powder is mixed with ammonium hydroxide and ammo...

Embodiment 2

[0055] Jatropha husk and oil meal were heated at 400 °C at a heating rate of 5 °C / min in N 2 Pyrolysis was carried out under air flow for 2 h to promote in-situ partial carbonization. Add 200 mL of oleum to 20 g of carbonized product, in N 2 The mixture was heated from room temperature to 150°C under airflow. Foaming occurs during heating. After heating at 150 °C for 16 h, a black solid was obtained, excess sulfuric acid was removed, and the black solid was repeatedly washed with a large amount of distilled water at 80 °C until the filtrate was neutral and free of sulfate ions. After filtration, it was dried in an oven at 70°C overnight, ground into powder, added with 10% polyethylene solution, dried in an oven at 70°C for 48 hours, and ground into fine particles to prepare component A; the oxide was mixed with glacial acetic acid, hydrogen Ammonium oxide and ammonium bicarbonate were mixed and calcined at 800℃ for 15min, α-Al 2 O 3 The powder was calcined at 900°C for 10...

Abstract

The invention discloses a diesel functional component preparation method, which comprises: 1, pyrolyzing jatropha curcas shells and oil meal to obtain a carbonized product, adding concentrated sulfuric acid, and heating to obtain a black solid; step 2, adding a polyethylene solution into the black solid, drying and grinding to obtain a component A; step 3, mixing and roasting a metal oxide, an acidic material and an ammonium-containing compound to obtain a component m; 4, alpha-Al2O3, an acidic material and an ammonium-containing compound are mixed and roasted, and a component n is obtained; and step 5, mixing the component m and the component n, then adding a polyvinyl alcohol solution, roasting and grinding into powder to obtain a component B, and mixing the component B and the component A to obtain the catalyst for preparing the diesel oil component, wherein the metal oxide is one or more of a group consisting of magnesium oxide, zinc oxide and nickel oxide. The catalyst is easy to separate from the product, can avoid discharge of a large amount of waste liquid, effectively prevents environmental pollution, is easy to activate and regenerate, and is convenient for continuous operation.

Description

technical field [0001] The invention relates to the technical fields of solid catalysis and the development of diesel functional components, in particular to a preparation method of diesel functional components and the obtained catalyst and application for preparing diesel components. Background technique [0002] The promulgation of my country's new environmental protection law, the promotion and application of National IV and National V clean diesel production, have put forward higher and higher requirements for diesel quality, the sulfur content in diesel has been strictly controlled, and the lubricity of diesel has gradually been exposed. The diesel hydrorefining process can reduce the sulfur content in diesel oil, but at the same time, it also removes the natural components (polar compounds) with lubricating function in diesel oil, and the viscosity of diesel oil is also reduced, which greatly reduces the lubricating performance of diesel oil, resulting in diesel oil. E...
