Embodiment Construction
[0028] The method for hydrogenating animal and vegetable oils and catalytic diesel oil of the present invention will be described in detail below through specific examples.
[0029] Such as figure 1 As shown, the flow process of the animal and vegetable oil and catalytic diesel hydrogenation method of the present invention is as follows: hydrogen enters the gas phase circulation hydrogenation reactor 6 from the bottom of the reactor through the pipeline 5, and the animal and vegetable raw material oil first enters the liquid phase circulation hydrogenation reaction through the pipeline 1 The low-pressure heat exchanger 2 of the device 13 exchanges heat with the liquid-phase hydrogenation effluent, and then passes through the raw oil pump 3, and after further heating, enters the gas-phase circulating hydrogenation reactor 6 through the pipeline 4 under the condition of gas-liquid countercurrent The hydrogenation refining and hydrogenation modification isomerization depreciation...
