Embodiment 1
[0048] In this example, the hydrogenation system uses residual oil as raw material, and the properties of the raw material are shown in Table 1. The reaction conditions of the hydrogenation system are as follows: the reaction temperature is 400°C, the operating pressure is 15MPa, and the space velocity is 0.3h -1 , the volume ratio of hydrogen to oil is 300, and the hydrogenation system cancels the existing circulating hydrogen system. The hydrogen production system adopts the hydrogen production process of natural gas steam reforming. The properties of the natural gas raw material are shown in Table 1; %Pd, 0.9wt%Ir, 0.9wt%Pt, the catalyst carrier is γ alumina), the reforming reaction temperature is 926~1012℃, and the gas hourly space velocity is 40000h -1 ; Water gas shift reaction temperature is 454 ℃. The reaction results are shown in Table 1.
[0049] In this example, polyimide (PI) was used as the hydrogen separation membrane material, polyethylene oxide block polymer...
