Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the three composite catalysts PSH / MOFs synthesized by the impregnation method are consistent with the characteristic peaks of the XRD diffraction pattern of the simulated standard powder, 2θ=7.4°, 8.5°, 12.0°, 14.2°, 17.1°, 22.3°, 25.7 °, the characteristic peaks at 33.1 correspond to the peaks of crystal planes 111, 002, 022, 113, 004, 115, 224, and 137, respectively. After loading the ionic liquid, the peak intensity of the crystal face of the zirconium-based MOFs is weakened, and the crystallinity is reduced, but the framework structure of the zirconium-based MOFs is still maintained.

[0026] figure 2 The above is the SEM image of different zirconium-based MOFs loaded with ionic liquids. It can be seen from the figure that the morphology and size of zirconium-based MOFs loaded with ionic liquids have not changed much. ...

Abstract

The invention discloses a method for preparing biodiesel by catalyzing jatropha curcas oil with zirconium-based MOFs material loaded ionic liquid. The method comprises the steps of synthesis of zirconium-based MOFs, preparation of ionic liquid, preparation of the zirconium-based MOFs supported ionic liquid and preparation of the biodiesel; the prepared composite catalyst can be conveniently recycled and stored, can also be directly used for preparing biodiesel from the catalyst, is green and pollution-free, and meets the requirements of green chemistry.

Description

technical field [0001] The invention relates to the technical field of biodiesel preparation, in particular to a method for preparing biodiesel from zirconium-based MOFs material loaded with ionic liquid to catalyze jatropha oil. Background technique [0002] Metal-organic frameworks (MOFs) materials are composed of metal centers or inorganic clusters as "nodes", carboxylic acid or nitrogen-containing organic multi-dentate ligands as linkers, and are porous with a periodic three-dimensional regular pore structure through coordination. crystal material. There are many kinds of MOFs, such as MILs, ZIFs, and UiOs series. Due to its advantages of high porosity, large specific surface area and functional controllable structure, it is widely used in gas adsorption and separation, catalysis, chemical sensing, optics and other fields. The UiOs series is also called zirconium-based MOFs. Zirconium-based MOFs have many advantages such as simple preparation and large specific surface...
