Embodiment 1

[0046] This embodiment is the preparation of carbon-based catalytic material and carbon-based catalyst

[0047] Dry the oil-containing scum, and then place it in a nitrogen atmosphere at 5°C / min to heat up to 400°C, 500°C, 600°C, and 700°C for 6 hours, and then obtain a carbon-based catalytic material after cooling;

[0048] Add the carbon-based catalytic material to 1mol / L hydrochloric acid for pickling to dissolve the metal on the surface of the carbon-based catalytic material, then wash it with pure water until neutral, and dry it at 70°C to obtain the carbon-based catalyst.

[0049] The carbon-based catalytic materials and carbon-based catalysts obtained by pyrolysis at 600 °C were selected for SEM and EDX characterization. figure 1 It is the SEM figure of the carbon-based catalytic material of the present embodiment, figure 2 It is the SEM figure of the carbon-based catalyst of this embodiment. Such as figure 1 and figure 2 As shown, carbon-based catalytic materials...

Embodiment 2

[0054] This example uses the carbon-based catalytic material provided in Example 1 to perform a degradation test on phenol

[0055] Choose respectively the carbon-based catalytic material of embodiment 1, choose 40ml, 50ppm phenol solution as target pollutant; With phenol, persulfate, carbon-based catalytic material mass ratio is 0.05:0.57:0.2; Take carbon-based catalytic material and add phenol solution Stir in medium, and add persulfate after adsorption equilibrium. All the reactions were carried out at a room temperature of 25° C.; the stirring rate was 500 r / min; the stirring time was 120 min.

[0056] Figure 5 It is a diagram of the degradation effect of carbon-based catalytic material activated peroxymonosulfate on phenol provided in Example 1 of the present invention. Such as Figure 5 As shown, within 80 minutes, the carbon-based catalytic material activates peroxymonosulfate to 40ml, and the removal rate of 50ppm phenol can reach 50%.

Abstract

The invention relates to the technical field of resource recovery, in particular to a carbon-based catalytic material and an application thereof. The invention discloses the carbon-based catalytic material, which is prepared by the following method: in the atmosphere of nitrogen or inert gas, pyrolyzing dried oil-containing dross to obtain the carbon-based catalytic material. According to the method, the oil-containing dross is recycled and used as a preparation raw material of the carbon-based catalytic material, so that the preparation cost of the carbon-based catalytic material is saved while the oil-containing dross is turned into wealth, and meanwhile, the pollution of the oil-containing dross is avoided; the carbon-based catalytic material can be obtained by one-step pyrolysis of theoil-containing dross, and the preparation method is simple and rapid. The carbon-based catalytic material activated persulfate is high in degradation rate of organic pollutants and high in degradation speed.

Description

technical field [0001] The invention relates to the technical field of resource recovery, in particular to a carbon-based catalytic material and its application. Background technique [0002] The development of the petrochemical industry has promoted economic development, but it has also brought a lot of pollutants, such as oily scum, etc. It is necessary to find an efficient and economical method to deal with oily scum. As the worldwide demand for refined oil continues to increase, the oily sludge produced by petroleum refining processes and related wastewater treatment processes is expected to grow at a faster rate, and a large amount of oily sludge and scum will accumulate worldwide. Oily sludge is a stubborn residue characterized by an emulsion of water, oil, fat, solids, organic compounds and metals. Among the organic compounds, the most common are a variety of refractory petroleum hydrocarbons (PHCs) such as alkanes, cycloalkanes, benzene, toluene, xylene, phenols and...
