Problems solved by technology

[0004] However, although the upgrading of biocrude oil and waste oil can reuse waste and generate alternative energy, the upgrading process of biocrude oil and waste oil needs to be carried out under high temperature and high pressure, and the catalyst cost is high , and the conversion rate of oil products is not ideal, so it is still not a commercially acceptable method to use bio-crude oil or waste oil for oil upgrading and reuse

Embodiment 1

[0027] Put 5% o-methoxyphenol (Guaiacol) and 95% n-tetradecane by weight in a metal reactor, use magnetite powder as a catalyst, and carry out hydrodeoxygenation reaction of oil at a temperature of about 280°C.

[0028] In this hydrodeoxygenation reaction, the hydrogen pressure is about 50atm (temperature is about 25°C), and the catalyst injection volume per unit time (WHSV) is about 10h -1 . Through GC-MS spectrum analysis, it can be known that the conversion rate of o-methoxyphenol is 99.97%.

[0029] Compared with the noble metal catalyst (Pd / ZrO 2 ), the cost of the magnetite powder catalyst used in the present invention is lower, and the conversion rate of o-methoxyphenol is higher.

Embodiment 2

[0031] Put 5% o-methoxyphenol (Guaiacol) and 95% n-tetradecane in a metal reactor, use ferric oxide powder as a catalyst, and carry out hydrodeoxygenation reaction of oil at a temperature of about 280°C .

[0032] In this hydrodeoxygenation reaction, the hydrogen pressure is about 50atm (temperature is about 25°C), and the catalyst injection volume per unit time (WHSV) is about 10h -1 . Through GC-MS spectrum analysis, it can be known that the conversion rate of o-methoxyphenol is 99.14%.

[0033] Compared with the noble metal catalyst (Pd / ZrO 2 ), the ferric oxide powder catalyst cost that the present invention uses is lower, but still has good o-methoxyphenol conversion rate.

Embodiment 3

[0035] Put 5% o-methoxyphenol (Guaiacol) and 95% n-tetradecane by weight in a metal reactor, use ferrous oxide powder as a catalyst, and carry out hydrodeoxygenation reaction of oil at a temperature of about 280°C.

[0036] In this hydrodeoxygenation reaction, the hydrogen pressure is about 50atm (temperature is about 25°C), and the catalyst injection volume per unit time (WHSV) is about 10h -1 . Through GC-MS spectrum analysis, it can be known that the conversion rate of o-methoxyphenol is 52.87%.

Abstract

The invention provides a method for modifying an oil product, which comprises the following steps that: ferriferous oxide is used as catalyst, the oil product and hydrogen are subjected to dehydrogenation deoxidation reaction, wherein the ferriferous oxide comprises iron protoxide (FeO), ferrous oxide (FeO2), ferric oxide (Fe2O3), ferroferric oxide (Fe3O4) or combination of FeO, FeO2, Fe2O3 and Fe3O4.

Description

technical field [0001] The invention relates to a method for improving oil products, and in particular relates to a method for improving oil products by hydrogenation with a catalyst. Background technique [0002] At present, oil upgrading methods are mainly divided into catalytic cracking and catalytic hydrogenation. Catalyst cracking is to use catalyst pores to control gasified hydrocarbons under high temperature and normal pressure to obtain liquid fuel, and the recovery rate is about 25wt.%. However, hydrogenation with traditional catalysts needs to be carried out under high temperature and high pressure, for example, the temperature is about 300-500° C., and the pressure is about 5-20 MPa (about 50-200 atm). When catalyst hydrogenation is used for oil upgrading, commonly used catalysts include precious metals, metal sulfides, etc., but the recovery of the catalyst is difficult, and the oil conversion rate depends on the catalyst used and the conditions, ranging from ab...
