Embodiment 1

[0032] The C4 fraction is fully hydrogenated in a rotating bed reactor in a supergravity field. The full hydrogenation of the C4 fraction is a gas-liquid-solid three-phase reaction, and the material used is H 2 , C4 fraction (the components are: butane, butene, butadiene and butyne), the catalyst is Pd / Al 2 o 3 , Temperature: 10~180°C, Pressure: 2~40atm, Speed ​​800~2100rpm. C4 space velocity 10~500hr-1, hydrogen / unsaturated bond (butene+2×butadiene+2×butyne+3×vinylethylene): 1.0~1.2mol / mol, circulation ratio: 5~9: 1.

[0033] The high-gravity rotating bed reactor adopts the structure shown in Figure 2, and the flow process is shown in Figure 4. The catalyst with an average particle diameter of 40 μm containing 0.4% (wt) Pd (made by the sol-gel process of Al 2 o 3 , spray-dried to obtain Al 2 o 3 Powder, sieved to obtain a carrier with an average particle size of 40 μm, and the catalyst) 15ml was suspended in the C4 raw material liquid by sieving, and hydrogen was intro...
