Embodiment 1

[0054] This embodiment provides a hogwash oil conversion process, comprising the following steps:

[0055] catalyst:

[0056] The catalyst is a waste agent of a desulfurizer with FeOOH as an active component, wherein, in the desulfurizer with FeOOH as an active component, the soluble iron salt Fe(NO 3 ) 3 9H 2 O is 6g, iron salt complexing agent triethanolamine 9g, amorphous iron oxyhydroxide 15g;

[0057] The above-mentioned desulfurizer with FeOOH as the active component is used to remove H in exhaust gas 2 The process of S is as follows: put H 2 S content is 5500mg / cm 3 exhaust gas at 3000h -1 The space velocity is passed into the desulfurization section, and the desulfurization reaction is carried out at 30°C. In the outlet gas of the desulfurization section, H 2 When the content of S is less than or equal to 0.01ppm, the waste in the desulfurization section is collected, which is the waste agent of the desulfurizer with FeOOH as the active component in this embodi...

Embodiment 2

[0067] The present embodiment provides a co-conversion process of wood tar and rancid oil, comprising the steps of:

[0068] catalyst:

[0069] The catalyst contains Fe 21.333 o 32 The regeneration of the waste agent of the desulfurization agent, wherein, the containing Fe 21.333 o 32 Among the desulfurizers, the magnetic iron oxide red Fe 21.333 o 32 55g, copper oxide 12g, carrier ferric oxide 21g;

[0070] The desulfurization process of the above-mentioned catalyst to coal pyrolysis gas containing hydrogen sulfide is as follows:

[0071] (1) The compressed coal pyrolysis gas is cooled to 30-35°C, mixed with the air from the air pump, and enters the desulfurization tower filled with the above-mentioned desulfurizer mainly with iron oxide as the active component, and adopts the process of bottom-in and top-out to avoid liquid water entering the desulfurizer bed to remove hydrogen sulfide;

[0072] (2) The above-mentioned desulfurizer becomes a waste agent after being ...

Embodiment 3

[0085] This embodiment provides an oil sand oil conversion process, comprising the following steps:

[0086] catalyst:

[0087] The catalyst is a waste agent of a desulfurizer with iron oxide as an active component, wherein, in the desulfurizer with iron oxide as an active component, calcium bicarbonate is 10g, basic copper carbonate is 12g, γ-Fe 2 o 3 18g, MnO 2 is 8g, NiO is 5g;

[0088] The desulfurization process of the above-mentioned desulfurizer with iron oxide as the active component is summarized as follows:

[0089] 1) Collect the tail gas produced by the fixed bed hydrogenation catalysis of medium and low temperature coal tar;

[0090] 2) The desulfurizing agent of this embodiment is made into columnar catalyst particles with a diameter of 1 mm and a length of 15 mm, and filled in the desulfurization tower to form a desulfurization layer;

[0091] 3) The above-mentioned tail gas is used for 2000h -1 The space velocity passes through the desulfurization layer...

Abstract

The invention belongs to the technical field of biomass utilization, energy and chemical engineering, and particularly relates to a multistage conversion process for inferior oil products. The multistage conversion process has the advantages that at least one type of iron oxide, desulfurization waste agents of the iron oxide or regeneration substances of the desulfurization waste agents of the iron oxide is used as catalysts, water-containing slurry is adopted, molar ratios of iron elements to sulfur elements in reaction systems are controlled, the fact that free radical condensation polymerization of the inferior oil products in pyrolysis procedures can be effectively blocked by means of carbonylation in the presence of CO is discovered, the CO and water can be converted and can be hydrogenated by active hydrogen, conversion reaction can be directly carried out on the inferior oil products during conversion reaction on the CO and the water, the liquefaction yield can be increased, anda large quantity of wastewater can be prevented after the conversion reaction is completely carried out.

Description

technical field [0001] The invention belongs to the technical fields of biomass utilization, energy and chemical industry, and in particular relates to a multi-stage conversion process of inferior oil products. Background technique [0002] With the rapid development of social economy, fossil non-renewable energy sources such as coal, crude oil, natural gas, and oil shale are becoming increasingly exhausted. At the same time, the CO produced by the combustion of such fossil non-renewable energy 2 , SO 2 , NO x Environmental pollution caused by pollutants such as pollutants is also becoming more and more serious, which forces human beings to think about ways to obtain energy and methods to improve the environment. [0003] At present, the conversion technology of inferior oil products has become a new means of obtaining energy. Inferior oil refers to oil products that are difficult to process with existing technologies, such as: oil sand oil, heavy oil, waste mineral oil, w...
