in 2010, while total production growth was entirely dependent on higher yields. In
the past 5 years, Chinese rapeseed planting area, production and total output have
shown an increasing trend. The total output has continuous record-setting in 2013–
2015. Planting area of peanuts has remained at 4.6 million hm

in 2013 has set a new record. Planting area of sunflower was 94.7 million hm
2 , but
the total output continued to grow. The area of sesame and flax planting showed a
slight downward trend, but the total output remained basically stable.
Although Chinese oil production has generally increased since the reform and
opening up, the market demand for oil products has risen linearly and the growth
of domestic production is far from meeting the growth of consumption. After China
joined the WTO in 2001, oil crops imports increased rapidly and the products with
the largest increase in imports were soybeans, palm oil and rapeseed. In the past
5 years, Chinese imports of oilseed materials were 63.52 million t, 75.58 million t,
83.15 million t, 87.93 million t and 90.48 million t, maintaining a continuous growth
trend, with an average annual import volume of 80.15 million tons, accounting for
about 57% of the global oilseed trade volume during the same period. China is the
largest oilseed importer of the world. In addition to the import of bulk oil, the import
of small yield oil such as sesame and flax has also been rising in recent years. China
is a traditional peanut exporting country. However, in recent years, due to changes in
market demand, price and quality competitiveness factors, peanut exports have been
declining and imports have risen rapidly.
In the past two decades, biodiesel has received widespread attention from countries
around the world because of issues such as climate warming, environmental pollution,
employment and ensuring energy supply security. Governments, scientific research
institutions and enterprises of the EU, the United States, Canada, Australia and Asia
work together to continuously increase the production and promotion of biodiesel
and many countries have entered the practical stage.
Some countries in Asia are also positively developing the biodiesel industry. Japan
was an early country to study biodiesel. In 1999, it established an industrialized
experimental base for the production of biodiesel from frying oil. At present, the
annual output of biodiesel in Japan has reached 40 * 104 t. Thailand’s first biodiesel
equipment has been put into operation and petroleum companies in Thailand are
committed to acquiring palm oil of 7 * 104 t and coconut oil of 2 * 104 t per year to
implement a tax reduction policy. South Korea and so on are also promoting the use
of biodiesel throughout the country.
The main material of biodiesel is animal or vegetable fats and there are many types
of oils and fats. In order to pursue low-cost biodiesel materials, chemical companies
around the world use different raw materials to try and explore. China has a wealth
of woody oil plant resources and the identified energy oil plant species account for
5% of the country’s seed plants. There are about 8,000 kinds of woody plants in
