Japanese Patent JP7121602
Kind Code:
B2
Abstract:
To provide a method for manufacturing new wax.SOLUTION: A method for manufacturing wax comprises: a first deposit step of adding a low temperature fluidity improver to hydrocarbon oil having a 10% capacity distillation temperature of 300°C or more to deposit a first solid at a temperature of 5-40°C; a first separation step of collecting the first solid as a first non-permeation by a solid liquid separation method; a second separation step of supplying the resultant solution obtained by dissolving the first solid in a solvent of 40°C or more including 80 capacity% or more of at least one kind selected from a group consisting of normal pentane and normal hexane to a separation membrane to collect a second permeation; a second deposition step of adding a solvent including 80 capacity% or more of at least one kind selected from a group consisting of 2-propanol, 2-butanone and acetone to the second permeation to deposit a second solid; and a third separation step of collecting the second solid as a third non-permeation by the solid liquid separation method.SELECTED DRAWING: Figure 1
