The present invention relates to a solid fuel including an oil-containing algmass and a fuel additive, and a method for producing the same. More particularly, the present invention relates to a method for producing a solid fuel including an alumi- mass containing an oil and a fuel additive, Which is capable of providing environmentally friendly alternative energy that can be used to produce electricity.

Alternative energy development is urgent due to the depletion of fossil fuels, rising energy demand, and high oil prices. Development of environmentally friendly alternative energy is a major global issue in response to global warming and various global environmental problems.

Renewable energy is being considered as the most realistic and promising alternative to solve these future energy shortages and greenhouse gas environmental problems at the same time. In particular, the Fukushima nuclear power plant accident caused by the Great East Japan Earthquake has emphasized the need for the development of clean and renewable energy more than ever.

There is a growing interest in marine biotechnology as a solution to these challenges.

Microalgae are photosynthetic underwater single-celled organisms, commonly referred to as phytoplankton. These microalgae are more than 220,000 species. If only water, sunlight, and carbon dioxide are supplied, they will be able to grow unlimitedly with photosynthesis. They can be mass-produced in a short time in various environments, and useful substances such as carbohydrates, proteins, and unsaturated fatty acids It is a rich eco-friendly resource.

Microalgae are currently considered as the most promising alternative sources with the following advantages: 1) Most microalgae varieties can be cultivated in salt-free land that can not be cultivated, and massive microalgae cultivation does not add any additional burden to food production . 2) Microalgae act as an effective carbon capture platform due to the high photosynthetic rate due to the unicellular structure and can accumulate up to 77% of dry cell mass in biomass. 3) According to conservative estimates, biodiesel production is 10 times smaller per unit area of land than in typical oil-bearing crops in microalgae.

Algae, on the other hand, refers to a group of lower plants that are composed of proteins, carbohydrates, fats, etc. and cultured in water. Such algae are generally referred to as the microalgae described above and are sun-exposed and cultured through photosynthesis.

Studies are underway to produce alternative energy through the use of algae oil extracted from the algae, according to the characteristics of rapid growth and reproduction of these species and their ability to grow smoothly in freshwater or seawater, regardless of the culture place.

The prior art regarding fuels using these microalgae and biomass is as follows.

Korean Patent No. 1354176 discloses a first heating process (S10) for heating the microalgae until water contained in the microalgae is phase-changed into water vapor.

In the second heating process (S30) Wherein the heat of the water vapor separated by the first heating step (S10) is used in the third biofuel production step (S50) of producing biodiesel and hydrogen by pyrolyzing the microalgae separated by the oil by the first heating step Discloses a biofuel production method using algae.
