[0047] Towards figure 1 The shown loop reactor (reactor volume 5L) is fed into the reaction kettle with methanol at room temperature with 40% of the kettle volume through the low-carbon alcohol feed port 101, and hydrogen gas is introduced into the reaction system through the air inlet until the system pressure is 1 MPa, and the opening The circulation pump 4 makes the liquid in the kettle flow slowly, and the gas is emptied, and the air in the loop reactor is replaced 6 times. After the last replacement, keep the pressure of the reaction system at 0.3MPa, and raise the temperature to 70°C (about 10 minutes during the heating process), adjust the circulating pump 4 to increase the liquid flow rate to a liquid linear velocity at the nozzle of 60m / s, and maintain the system circulation.
