Embodiment 1

[0040] Prepare 0.35mol / l butyl titanate solution in absolute ethanol, take 100ml and add 35mmol dodecyldimethyl tertiary amine (DMA12) as template agent, add 35mmol glacial acetic acid while stirring, make it and Butyl titanate forms a chelate. Add 100ml of deionized water to the sol to make the colloidal particles form an open skeleton structure; at the same time, slowly add 57.53g of aluminum isopropoxide, the sol gradually loses its fluidity and forms a gel. The gel was dried at a constant temperature at 100°C for 24 hours to remove moisture, organic groups and organic solvents in the gel. Put the prepared crystal into a muffle furnace and program the temperature to 550°C for 4 hours to obtain TiO 2 -Al 2 o 3 The composite support is denoted as TiAl-1.

Embodiment 2

[0042] Prepare 0.79mol / l butyl titanate solution in absolute ethanol, take 100ml and add 78.8mmol cetyltrimethylammonium bromide (CTAB) as template agent, add 78.8mmol propionic acid while stirring, Make it form a chelate with butyl titanate. Add 100ml of deionized water to the sol to make the colloidal particles form an open skeleton structure; at the same time slowly add 43.33g of aluminum isopropoxide, the sol gradually loses its fluidity and forms a gel. The gel was dried at a constant temperature at 100°C for 24 hours to remove moisture, organic groups and organic solvents in the gel. Put the obtained crystal into a muffle furnace and program the temperature to 500°C for 4 hours to obtain TiO 2 -Al 2 o 3 The composite support is denoted as TiAl-2.

Embodiment 3

[0044] Prepare 0.60mol / l titanium tetrachloride TiCl in absolute ethanol 4 Solution, take 100ml and add 59.9mmol polyvinylpyrrolidone (PVP) as template agent, add 59.9mmol oxalic acid while stirring, make it and TiCl 4 Chelates are formed. Add 100ml deionized water to the sol to make the colloidal particles form an open skeleton structure; meanwhile slowly add 90.79g Al(NO 3 ) 3 9H 2 O, the sol gradually loses its fluidity and forms a gel. The gel was dried at a constant temperature at 100°C for 24 hours to remove moisture, organic groups and organic solvents in the gel. Put the prepared crystal into a muffle furnace and program the temperature to 550°C for 4 hours to obtain TiO 2 -Al 2 o 3 Composite support TiAl-3.

The catalyst has good reactivity, stability and selectivity, and can be applied to the reaction of catalyzing the degradation of aromatic compounds from biomass oil, and can also be applied to the addition of compounds containing aromatic C-O bonds or alkyl C-O bonds. Hydrogen deoxygenation reaction.

Description

technical field [0001] The invention relates to the technical field of preparation and application of catalytic materials, in particular to a highly active iron-nickel bimetallic catalytic material and its application in the hydrodeoxygenation (HDO) reaction of substances with high aromatic ether and phenol content. Background technique [0002] As a renewable energy, bio-oil has been considered as the most potential substitute of fossil energy. However, bio-oil contains a large amount of oxygen-containing compounds such as phenols, aldehydes, alcohols and ketones, etc., and the oxygen content is as high as more than 40%. Excessive organic oxygen-containing compounds will not only increase the viscosity of the oil, but also reduce the The volatility of the oil will also reduce the stability of the oil. Hydrodeoxygenation (HDO) is currently the most important means of removing oxygen from oil in industry. Therefore, the research and development of highly active hydrodeoxyge...
