Description

[Detailed description of the invention] The present invention relates to fuel oil flow propensity.

As is well known, when fuel oils such as petroleum oil and heavy oil are heated to low temperatures, the balaf and waxes contained therein are precipitated. Because of this, the fluidity is extremely low 1'L, which can become a problem.

1 (11e) When the O5 temperature rises in winter, the paraffin wax contained in diesel oil precipitates, clogging the fuel filter or losing fluidity, which can impede the operation of the De F-Ville engine. There are many examples of this.

Furthermore, when heavy oil becomes low in ail, it loses its fluidity due to the precipitation of paraffin wax, making it impossible to transport or burning the grain in a burner.

In addition, although imported crude oil has tended to be heavy in recent years, light fractions such as naphtha and heavy oil are
As the required ratio is increasing, light oil and heavy oil tend to become heavier and have lower fluidity.

For this reason, to improve cold fluidity and flow properties,
Flowability enhancing agents have been known for a long time, which are added to fuel oil to change the shape of wax crystals and maintain fluidity even at low temperatures.

Typical examples include polyalkyl methacrylate-1-1 chlorinated paraffin, carbon-naphthalene condensates, alkenyl succinic acid amides, and ethylene-vinyl acetate copolymers.

These provide excellent low-temperature fluidity for fuel oils such as light oil and heavy oil, and prevent filter 1.1 clogging at low temperatures.11. It has excellent properties such as:

However, these flowability agents have different effects on low-temperature fluidity and flow characteristics depending on the type of crude oil from which the fuel oil is extracted or changes in the distillation temperature range, and therefore, the fluidity characteristics that should be fully satisfied are different. The reality is that a second drug has not yet been found.

The inventors of the present invention have conducted extensive research to improve the above-mentioned points, and have finally arrived at the present invention.
