Embodiment 1

[0030] The hollow box type Pd / MOF catalyst provided by the invention, its preparation process is:

[0031] a) Dissolve 1mmol of Ni(OH)2 in 10mL of water and mix it with polyvinylpyrrolidone (PVP, 0.163g, molecular weight: 24000). After the solution is mixed evenly, solution A is prepared.

[0032] b) Then squaraine and acetic acid were added dropwise into 10mL of deionized water rapidly and continuously, so that the concentration of squaraine was (0.67mmol / L), and the concentration of acetic acid was (100mmol / L), and solution B was prepared.

[0033] c) Then A and B solutions were mixed and transferred to a polytetrafluoroethylene-lined hydrothermal kettle (50 mL capacity), and stirred for 30 minutes. Then put it into a heating furnace and heat it at 140°C for 48h.

[0034] d) After the reaction time of 48h is over, the obtained solid is washed three times with water and ethanol respectively to obtain a green solid, and finally vacuum-dried at room temperature to remove moist...

Abstract

The invention discloses a preparation method of a Pd / MOF catalyst for phenol catalytic hydrogenation upgrading, and relates to the technical field of catalysts, the preparation method comprises the steps of preparation of a Ni-containing MOF carrier, Pd loading and the like, and the prepared hollow box type Pd / MOF catalyst has high activity for phenol catalytic hydrogenation in a water phase; a phenol extraction step from sawdust pyrolysis to phenol catalytic hydrogenation is reduced, the reaction efficiency is improved, and the energy loss is reduced. Meanwhile, catalytic hydrogenation of phenol can also be carried out in a normal-pressure H2 atmosphere, so that the energy consumption in the hydrogenation process is further reduced, and the requirements on reaction equipment are further reduced.

Description

technical field [0001] The invention relates to the technical field of catalysts for catalytic hydrogenation and upgrading of biomass, in particular to a method for preparing a Pd / MOF catalyst for catalytic hydrogenation and upgrading of phenol. Background technique [0002] The excessive consumption of fossil fuels has raised concerns about environmental issues and national energy security, therefore, there is an increasing demand for alternative fuels that are environmentally friendly and renewable. Currently, biomass, as an alternative renewable carbon source, plays an increasingly important role in the chemical industry and is one of the promising renewable energy sources. However, direct utilization of biomass as liquid fuel is not feasible because of high oxygen content, low combustion calorific value, poor chemical stability and strong corrosiveness of biomass, which hinder the practical use of the product as a renewable energy source. The main product of biomass pro...
