Embodiment Construction

[0032] The mesoporous catalyst with high hydrothermal stability of the present invention, its preparation method and the method of using it to catalyze hydrothermal liquefaction of microalgae to prepare bio-oil are described in detail below in conjunction with examples and accompanying drawings.

[0033] Catalyst preparation example

[0034] Dry a certain amount of SBA-15 in vacuum at 110°C for 12 hours, add a certain amount of dichloromethane and a certain amount of hydrosilane after cooling to room temperature, add a certain amount of catalyst tris(pentafluorophenyl)borane after about 2 minutes, and ultrasonically treat for about 5min, and finally filtered. During the process, a large amount of dichloromethane was first used, and then washed with a large amount of n-hexane. The white solid obtained after filtration was vacuum-dried at 110°C and became a mesoporous catalyst. The name is shown in Table 1.

Abstract

The invention discloses a mesoporous catalyst with the hydrothermal stability.The mesoporous catalyst is prepared by grafting organic functional groups to the surface of an SBA-15 type mesporous molecular sieve, wherein hydrogen-containing silane is adopted as a reagent for grafting the organic functional groups, the structural general formula is as shown in the description, and R1, R2 and R3 represent the different organic groups or the same organic group.The invention further discloses a method for preparing bio-oil by catalyzing hydrothermally-liquidized microalgae through the mesporous catalyst with the hydrothermal stability.

Description

technical field [0001] The invention relates to a mesoporous catalyst with high hydrothermal stability and a preparation method thereof, which is used in a method for preparing bio-oil by catalyzing liquefaction of microalgae, and belongs to the field of utilizing mesoporous catalyst materials and the field of renewable biomass energy. Background technique [0002] Energy and the environment are the two major themes of human development. Currently, fossil energy reserves are limited and gradually exhausted, and the use of fossil energy has brought serious environmental pollution. Therefore, the development of renewable energy can help reduce dependence on fossil resources, which is of great significance. The energy consumption of my country's transportation industry is huge, and it is increasing year by year. It currently accounts for more than 20% of the total energy consumption of the society, and it is expected to reach 1 / 3 of the same level as developed countries in recen...
