Biofuel development from ...

Reasons to focus on algae
● Algae oil production capacity is several tens to several hundreds of terrestrial oil and fat plants
● Small area required for production
● Does not compete with food
● No need for cultivated land for production (Utilizing leave sites)
This is the biggest reason why people around the world are paying attention to algae
Types of combustion produced by algae
The fuel of algae is divided into three plus one.
1. Seaweed mainly
Because it makes various carbohydrates, we do not produce much oil.
Therefore, take alcohol from carbohydrates.
It is one flow of bio-alcohol.
2. Most microalgae make
The same ingredients as those of vegetable oil such as so-called vegetable oil rapeseed oil
Oil · triglyceride → biodiesel (FAME) via bio (HiBD)
This oil can not be used directly for oil fuel.
When using it as a fuel, do the thing called methyl ester dan, the point is to use the glyceride removed.
This is what we call biodiesel fuel.
Although it comes with the name of diesel, it is completely different in nature from what is called diesel via, and it is one with a lot of oxygen intruded.
Since there are various restrictions when using biodiesel containing a lot of oxygen, "Because it is a bit problematic as it is"
Recently, the concentration of oxygen is converted by hydrogen conversion and brought to so-called hydrocarbon,
There is a trend of using it as a bio diesel oil.
3. A small group of algae
It is typified by Botryococcus Orlando Chicken Limm,
This oil is a petroleum type oil.
That is, it becomes hydrocarbon.
Hydrocarbon (bio b heavy oil) → Currently operated fuel
This can be converted to light oil, jet fuel, gasoline even with refining technology possessed by a modern oil company.
We will show each of the advantages and disadvantages as well.This has this kind of thing.
Botryococcus Botryococcus
● Algae inhabiting freshwater
● Form a colony of 30 to 30 to 500 pm from green to red
● Fix carbon dioxide and produce hydrocarbons
● Hydrocarbon is a complete oil substitute resource
● Hydrocarbons accumulate in cells and inside colonies (20.75% of dry weight)
Each cell is elliptical one
The horizontal axis is 20 microns and the vertical is 10 microns,
Each one is independent, but it can not become disjoint even after division,
Since the surroundings are viscous, they stick together and make colonies.
So, the hydrocarbons that were made are synthesized first in the cell, but that comes out.
Outside hydrocarbons do not spread in the liquid, but are basically trunked inside this colony.Colonies - ranked among so-called cells.
Therefore, if you crush this colony, this will come out of the corner, the colocoro.
This is hydrocarbon oil.This is the time of crushing.
It is the hydrocarbon that comes out when you crush.
Therefore, since it is outside the cell and just fills the cell,
Extracting hydrocarbon oil is an organism that has such a characteristic that it can be extracted easily without breaking the cell.
Aurantiochiytrium
In addition to Botryococcus there is another heterotrophic algae oranthium oxide which makes hydrocarbons.
This will not produce photosynthesis.
When you give organic matter, it will increase tremendously using its organic matter.
And it has the property of producing hydrocarbons.
Compared with Botryococcus, the efficiency of this organism to produce hydrocarbons,
It is a creature that will make it at a rate 10 times higher than that.
The shape of a living thing is just a spherical shape.
When I look at the microscope with a special stain that dyes only oil in this spherical shape,
Dyeing oil turns yellow. It is pale yellow.
You can see that it is making oil very well.
B heavy oil is an oil obtained by mixing c heavy oil and diesel oil in half, so it has intermediate characteristics.In terms of density, it is just density like light oil.
Another important kinematic viscosity, sticky, then.Whether it is smooth.
When I look at it, it looks very heavy from heavy oil,
B It can be said that it has a feeling of smoothness quite close to heavy oil or light oil.
I tried spraying Botrio oil and light oil.
The timing was delayed for a while but the oil of Botryococcus definitely exploded.
Timing shifted because light oil is heavier, explosion takes place in a short time like diesel if slight pressure is applied.
It was introduced in the program of the New Year this year (2012), because the car would move as it actually exploded, but by mixing 70% with light oil, it was said that the Mazda CX - 5 was successfully runIt is a thing.
Four models of commercialization of algae biomass
1.Fuel use model Used as fuel for passenger cars, agricultural machinery, and ships
2.Energy source model fuel for power generation, use as a heat source
3.Health industry model Cosmetics, use as health food
4.Chemical industry model Use as a chemical product such as plastics
Taking full advantage of the potential of local resources and algae biomass,
New industries that are environmentally friendly, contribute to energy and health
Fuel model.
