[0055] Will figure 2 The process flow diagram of the ebullating bed reactor used in the cold mold device of the 5000L / h ebullating bed reactor is as follows Figure 4 shown.
[0056] 1. Process flow
[0057] The tap water comes from the water tank b, and after the tap water is pressurized by the circulation pump c (higher than the internal pressure of the reactor), it enters the reactor from the mixed-phase inlet at the bottom of the ebullated bed reactor a; the air in the atmosphere is pressurized by the air compressor d Stored in the gas storage tank e, the air enters the reactor from the outlet of the gas storage tank e and the mixed-phase inlet at the bottom of the ebullated bed reactor a. Under the action of the momentum transfer of tap water and air, the catalyst particles in the ebullated bed reactor a reach a fluidized state. In the ebullated bed reactor, the gas-liquid-solid three-phase mixture is separated by the three-phase separator at the top of the reactor, t...

[0067] Will figure 2 The schematic diagram of the process flow of the ebullated bed reactor used in the 200L / h straw pyrolysis liquid hydrodeoxygenation unit is as follows Figure 5 shown.
[0068] 1. Process flow
[0069] The raw material and the hydrogen donor enter the reactor from the coaxial feeder on the side of the fluidized bed reactor a, wherein the raw material is straw pyrolysis liquid. The control range of feed temperature of raw material and hydrogen donor is from room temperature to 45°C, and the mass ratio of hydrogen donor to raw material is generally controlled to be 0.25 to 2:1. The hydrogen-donating agent can come from diesel oil or wax oil distillate obtained by fractionating the fluidized bed hydrodeoxygenation product of the raw material, or diesel oil or wax oil distillate with high aromatic content outside the device. The circulating oil comes from the oil phase outlet g-1 of the cold high-pressure separator g. After the circulating oil is pressuriz...

[0079] Will figure 2 The schematic diagram of the process flow of the ebullated bed reactor used in the 100L / h wood chip pyrolysis liquid hydrodeoxygenation unit is as follows Figure 6 shown.
[0080] 1. Process flow
[0081] The raw material and the hydrogen donor enter the reactor from the coaxial feeder on the side of the ebullated bed reactor a, wherein the raw material is wood chip pyrolysis liquid. The control range of feed temperature of raw material and hydrogen donor is from room temperature to 45°C, and the mass ratio of hydrogen donor to raw material is generally controlled to be 0.25 to 2:1. The hydrogen-donating agent can come from diesel oil or wax oil distillate obtained by fractionating the fluidized bed hydrodeoxygenation product of the raw material, or diesel oil or wax oil distillate with high aromatic content outside the device. The circulating oil comes from the oil phase outlet g-1 of the cold high-pressure separator g. After the circulating oil is p...
