Liquid fuel reforming and blending method

Abstract

A liquid fuel reforming and blending method, whereby after heavy oils are dissolved in alkanes, the blending method is utilized to form a fuel applicable for usage in diesel oil combustion systems and slow-speed diesel engine systems. Wherein the alkanes employed are polyaromatic alkanes (C9˜C20) acquired from reforming oil from bottom of a gasoline tower or reforming oil from bottom of an aromatics extractive tower. The alkanes and the heavy oils are blended in percentage proportions by weight ranging from 10% to 90%, which thereby achieves a flash point temperature of above 45° C. Thus, by means of the reforming and blending method, after blending the heavy oils and the alkanes, a new type heavy fuel oil is converted therefrom, thereby increasing economical value of the heavy oils.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a liquid fuel reforming and blending method, and more particularly to the reforming and blending method which converts waste heavy oils into a fuel applicable for usage in various combustion systems, and which thereby increases economical value of waste heavy oils and reduces environmental pollution. [0003] (b) Description of the Prior Art [0004] Because of low price and safe storage of heavy oils, majority of industrial fuel systems are fueled by the heavy oils. However, boiling points of the heavy oils are too high, with A-class heavy oils having a boiling point of 338° C., while B-class and C-class heavy oils have boiling points as high as 480° C., and thus such heavy oils are difficult to vaporize. Therefore, though several types of heavy oil combustion furnaces are adapted to employ various methods to enhance atomization or vaporization of the heavy oils, including high-pressur...

AI Technical Summary

Benefits of technology

[0007] A primary objective of the present invention is to resolve and eliminate the aforementioned shortcomings, whereby, because of property of alkanes to increase atomization, the present invention employs the alkanes as a combustion-supporting agent, and after heavy oils are dissolved in the alkanes, a blending method is utilized to form a fuel applicable for usage in various combustion systems, and which thereby achieves objectives of increasing economical value of the heavy oils and reducing environmental pollution.

Problems solved by technology

However, boiling points of the heavy oils are too high, with A-class heavy oils having a boiling point of 338° C., while B-class and C-class heavy oils have boiling points as high as 480° C., and thus such heavy oils are difficult to vaporize.

Therefore, though several types of heavy oil combustion furnaces are adapted to employ various methods to enhance atomization or vaporization of the heavy oils, including high-pressure spraying, rotary-type methods, and so on, because the heavy oils are not easily vaporized, and, moreover, because the heavy oils are of high viscosity, incomplete vaporization and large atomized particles result.

Hence, inability to achieve complete combustion not only results in loss of a large amount of calorific value, but also dense smoke is produced as a consequence of the incomplete combustion, which causes pollution of the atmosphere.
