Embodiment

[0034] This embodiment provides a candle special wax and its preparation method. The preparation steps are as follows:

[0035] (1) Using a Fischer-Tropsch synthetic wax as a raw material, obtain a Fischer-Tropsch synthetic refined wax through hydrogenation refining, the hydrogenation temperature is 280 ° C, and the operating pressure is 7 MPa; then perform sweating and deoiling operations on it to obtain a deoiled refined wax .

[0036] (2) Preheat the deoiled and refined wax to 110°C in the raw material tank, transport it to the first molecular evaporator at a feed rate of 9kg / h, control the temperature at 200°C, and the pressure at 45Pa, and cut off the fraction 460°C distillate sections. Among them, the 400-460°C fraction is the intermediate product A at 40-60°C.

[0037] (3) The >460°C distillate section is used as a raw material, and is transported to a molecular evaporator at a feed rate of 9kg / h (no light components are distilled out in the first evaporator, and dire...
