preparation Embodiment 1

[0075] refer to figure 1 The schematic diagram of the preparation process of the catalyst support and figure 2 Schematic diagram of the catalyst preparation process, the preparation method of the oil hydrodeoxygenation upgrading catalyst in this example is as follows:

[0076] (1) Preparation of the catalyst carrier: mix active γ-alumina powder with Y-type zeolite and mesoporous activated carbon according to the required ratio to obtain a mixture. In the mixture, active gamma-alumina, Y-type zeolite and mesoporous activated carbon account for 80%, 16% and 4% of the mass of the mixture respectively. Then grind the mixture to below 200 mesh and stir well. Next, 1.5% of the total mass of scallop powder is added to the mixture, and then 1.5 times of the mass of the mixture is added with 10% nitric acid solution. After kneading for 60 minutes, it is repeatedly extruded on an extruder for several times and extruded to obtain a molding carrier. After drying the molded support at ...

[0080] refer to figure 1 The schematic diagram of the preparation process of the catalyst support and figure 2 Schematic diagram of the catalyst preparation process, the preparation method of the oil hydrodeoxygenation upgrading catalyst in this example is as follows:

[0081] (1) Preparation of catalyst carrier: mix activated γ-alumina powder with HY-type zeolite and mesoporous activated carbon according to the required ratio to obtain a mixture. In the mixture, activated γ-alumina, HY type zeolite and mesoporous activated carbon account for 82%, 14% and 4% of the mixture mass respectively. Among them, mesoporous activated carbon was used as a pore expander. Then grind the mixture to below 200 mesh and stir well. Next, 1.5% of the total mass of scallop powder is added to the mixture, and then 1.5 times of the mass of the mixture is added with 10% nitric acid solution. After kneading for 60 minutes, it is repeatedly extruded on an extruder for several times and extruded to...

[0085] refer to figure 1 The schematic diagram of the preparation process of the catalyst support and figure 2 Schematic diagram of the catalyst preparation process, the preparation method of the oil hydrodeoxygenation upgrading catalyst in this example is as follows:

[0086] (1) Preparation of catalyst carrier: Mix active γ-alumina powder with USY zeolite and mesoporous activated carbon according to the required ratio to obtain a mixture. In the mixture, active gamma-alumina, USY type zeolite and mesoporous activated carbon account for 80%, 15% and 5% of the mass of the mixture respectively. Then grind the mixture to below 200 mesh and stir well. Next, 1.5% of the total mass of scallop powder is added to the mixture, and then 1.5 times of the mass of the mixture is added with 10% nitric acid solution. After kneading for 60 minutes, it is repeatedly extruded on an extruder for several times and extruded to obtain a molding carrier. The molded support was dried at 40 °C fo...

Abstract

The invention discloses an oil product hydrodeoxygenation upgrading catalyst and a preparation method and application thereof. The oil product hydrodeoxygenation upgrading catalyst comprises a catalyst carrier, and an active component and an auxiliary agent which are loaded on the catalyst carrier, wherein the active component comprises ruthenium oxide, molybdenum oxide, nickel oxide and / or cobaltoxide; the catalyst carrier comprises gamma aluminum oxide, zeolite and activated carbon; the auxiliary agent comprises phosphorus oxide; in the active component, the molar ratio of ruthenium oxide to molybdenum oxide to nickel oxide and / or cobalt oxide is (0.2-1): (10-28): (2-10). The oil product hydrodeoxygenation upgrading catalyst has the characteristics of high activity and conversion rate of low-temperature hydrodeoxygenation, good selectivity, repeated long-term recycling, good stability, strong coking resistance, good hydrothermal stability and good acid and water resistance, and thepreparation method is simple and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of oil refining, in particular to an oil hydrodeoxygenation upgrading catalyst and its preparation method and application. Background technique [0002] With the rapid development of the economy, oil resources are increasingly scarce, and people pay more and more attention to environmental issues. How to effectively use biomass renewable resources to pyrolyze into bio-crude oil and further improve the quality of green fuel oil has become a research topic that has attracted extensive attention. This is the need to reduce and eliminate environmental pollution from the source, has very broad application prospects, and conforms to the trend of clean fuel oil development. [0003] The composition of bio-oil produced by high-temperature pyrolysis of biomass is complex. In addition to containing a large amount of water, it also contains almost all types of oxygen-containing organic compounds, such as phenols, fura...
