content is more than 40%, and is the main raw material tree species for extracting
bio-friendly clean diesel oil. The biodiesel produced by Jatropha curcas seeds can
be used in all kinds of diesel engines, and the key techniques such as flash point,
freezing point, sulfur content, carbon monoxide emission, particle value and so on
are suitable for all kinds of diesel engines. Compared with the traditional diesel oil,
Jatropha curcas biodiesel has the advantages of cleaner and higher efficiency, and
its performance is obviously better than that of ordinary diesel oil and other plant
diesel oil.
Oil tree species are resistant to barren, good planting and have certain economic
value. While not affecting the normal local agricultural production activities, many
areas have carried out “energy farms”, the so-called “energy farms”, that is, countries
according to their specific national conditions. In order to develop energy and solve
the energy crisis, the biomass production base is mainly based on planting plants with
high photosynthetic efficiency and for the purpose of obtaining energy. Through the
rational planning of the land, the “energy farm” makes the best use of mountains,
uncultivated wasteland and water area, selects the biomass varieties suitable for the
local growth conditions, and breeds and propagates biomass on a large scale in order
to obtain a sufficient number of high-yielding plants, and is processed into available
energy.
At present, there is no clear stipulation on the classification of “energy farm” in the
theoretical circle. I think, according to the region where energy plants are cultivated,
“energy farms” can be divided into “energy forest farms” that use mountainous areas
to grow woody plants and “energy fishing grounds” that use water area to cultivate
energy crops. Since chemist Calvin succeeded in growing large areas of petroleum
plants in California in 1986, there has been a rapid wave of development and research
on petroleum plants around the world. The oil “energy forest farm” is divided into
two kinds: one is that the planted woody plants produce hydrocarbons, which can
be extracted into fuel; the other is made into fuel. Woody plants directly produce
almost petroleum fuel. At present, the research on energy farms at home and abroad
is mainly based on the study of energy plants.
Energy plants usually refer to plants that have the ability to synthesize higher
reductive hydrocarbons and can produce products close to oil composition and alternative petroleum use, as well as plants rich in oil. In a broad sense, energy plants
contain all land and marine plants. Energy plants in a narrow sense refer to plants
(not grains) that contain oils or similar substances.
From the domestic point of view, the research on energy plants in China started
a little late, mainly concentrated on for more than 10 years after 1990. Although the
development speed is relatively fast, there is still a big gap with the advanced level of
the world. At present, the research mainly focuses on oil-rich energy plants such as
Camellia oleifera Abel, Elaeagnus angustifolia and other carbohydrate-rich energy
plants. The necessity of planting energy plants in a large area is as follows:
