Embodiment 1～5 and comparative example 1

[0045] Now carry out test detection to embodiment 1~5 and comparative example 1:

[0046] 1. XRD detection

[0047] Adopt X-ray diffractometer to detect the transition metal doped 3R type molybdenum disulfide catalyst that embodiment 1~18 makes, take embodiment 1 as example, as figure 1 As shown, the Ni-doped 3R molybdenum disulfide catalyst only contains the characteristic diffraction peaks of 3R crystalline molybdenum disulfide, and no characteristic diffraction peaks of 2H molybdenum disulfide and nickel are detected, indicating that under the induction of the inorganic salt microstructure , can directly form nickel-doped 3R molybdenum disulfide.

[0048] 2. Detection of catalytic reaction activity

[0049]The transition metal-doped 3R-type molybdenum disulfide catalyst prepared in Examples 1-18 is used to catalyze the hydrogenation reaction of oleic acid, taking Example 1 as an example, and the Ni-doped 2H-type molybdenum disulfide commercial catalyst of Comparative Exam...

Abstract

The invention relates to the technical field of oleic acid hydrogenation, and particularly discloses a preparation method of a transition metal doped 3R type molybdenum disulfide catalyst. The preparation method comprises the following steps: 1, grinding and mixing sodium molybdate, a transition metal salt precursor, sodium thiocyanate and inorganic salt by using a ball mill for not less than 6 h;and 2, carrying out annealing treatment on the mixture obtained in step 1 at an annealing temperature of not less than 300 DEG C, cooling to room temperature after the reaction is finished, dissolving and washing the reacted mixture with a solvent, and drying the reacted mixture to obtain the transition metal doped 3R type molybdenum disulfide catalyst. The transition metal doped molybdenum disulfide with the crystal form of 3R prepared by adopting the technical scheme in the patent has better hydrogenation reaction capability compared with a commercial doped molybdenum disulfide catalyst.

Description

technical field [0001] The invention relates to the technical field of hydrogenation of oleic acid, in particular to a preparation method of a transition metal-doped 3R type molybdenum disulfide catalyst. Background technique [0002] With the rapid development of the economy, the human demand for various oil products has increased significantly, and the waste oil formed has also continued to increase. Among them, catering waste oil is rich in C, H and O elements, mainly composed of C 12 -C 24 If fully utilized, it can effectively alleviate the energy crisis and maintain ecological carbon balance. At present, through the catalytic hydrodeoxygenation reaction, the animal and vegetable oils containing unsaturated fatty acid esters are converted into saturated linear or isomerized diesel alkanes, the calorific value and cetane number are significantly improved, and the quality of biodiesel is improved. workers' attention. [0003] Molybdenum disulfide has good hydrodeoxygen...
