Benefits of technology

[0010]Therefore, by removing glycerin or reducing the amount of glycerin, it is possible to accomplish an improvement in combustibility and an increase in combustion calorie per unit weight. By removing glycerin more completely, the water-insolublized fatty acid substance can be processed into a solid or powder form, which can be used as a solid fuel excellent in handleability.
[0025]The particle of the water-insolubilized fatty acid coated with the film substance of the present invention can further be made into a pellet or a block in any shape and size using a pelletizer or the like, whereby a solid fuel more excellent in handleability can be obtained.

Problems solved by technology

In the manufacture, a crude glycerin including a fatty acid and a glycerin as main components is produced as a by-product in a large amount, and a majority thereof is wasted without being utilized effectively.
(1) The crude glycerin has a high pH value due to the effect of an alkali catalyst used in the manufacture of BDF, and thus deteriorates combustion equipment such as a boiler.
Those ionic species may deteriorate combustion equipment.
(3) Although the combustion of the crude glycerin generates no harmful substance such as dioxin, it is known that it generates soot dust in a large amount.
If the amount of the soot dust to be generated cannot be reduced, it is difficult to use the crude glycerin as the fuel.

[0049]Crude glycerin produced as a by-product in the manufacturing process of a BDF from wasted edible oils by a transesterification reaction under potassium hydroxide catalysis was obtained from a BDF manufacturer, Sebec Co., Ltd. An experiment of producing a fuel according to the present invention was carried out using this. Crude glycerin obtained from Sebec Co., Ltd. was used as a sample A.

[0050](1) Production of Fatty Acid Magnesium Salt

[0051]An aqueous solution of crude glycerin was made by dissolving 20 g of crude glycerin in 100 g of purified water. A fatty acid magnesium salt was precipitated by adding 100 g of a solution of 20% magnesium chloride hexahydride by little and little to the aqueous solution of crude glycerin while stirring with a stirrer. As a result, a dark-brown suspension formed of the precipitated fatty acid magnesium salt, glycerin, potassium ions, water, and the like was obtained.

Abstract

The objective is to obtain fuel having high combustion calorie and superior handleability from a crude glycerin or a fatty acid mixture that have been discarded as industrial waste products. Disclosed is a fuel comprising a water-insolublized fatty acid substance obtained by water-insolubilizing a fatty acid that is contained in a crude glycerin or fatty acid mixtures that are produced as by-products in the process of producing a biofuel from an animal / plant-derived fat / oil. The water-insolublized fatty acid substance is preferably a water-insoluble fatty acid salt, particularly preferably a salt of a fatty acid with a divalent or trivalent metal ion.

Description

TECHNICAL FIELD[0001]The present invention relates to a fuel, which uses, as a raw material, crude glycerin or a fatty acid mixture produced as a by-product in a process of producing a biofuel from an animal / plant-derived fat / oil, and a method of manufacturing the same.BACKGROUND ART[0002]A biodiesel fuel (BDF), which uses biomass as a raw material, has attracted great attention in the light of problems such as depletion of fossil fuels and environmental loads due to CO2 emission in recent years.[0003]The BDF is manufactured by a transesterification reaction between alcohols and animal or plant oils extracted from plants such as soybeans, palm, and maize or animals such as cattle, swine, sheep, and fishes. In the manufacture, a crude glycerin including a fatty acid and a glycerin as main components is produced as a by-product in a large amount, and a majority thereof is wasted without being utilized effectively.[0004]Meanwhile, the crude glycerin has a calorie of about 5,400 kcal / kg...
