There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
Mineral oil is the most used insecticide, both in acrage and in volume. 34,508,857 pounds (15,652,972 kg) of mineral oil was sprayed on 4,543,066 acres (about 1.8 million hectares). 1 to 4% solutions in water are sprayed, which is hundreds of times more than modern synthetic insecticides. Mineral oil is correspondingly cheaper.
Waste oil is oil containing not only breakdown products but also impurities from use. Some examples of waste oil are used oils such as hydraulic oil, transmission oil, brake fluids, motor oil, crankcase oil, gear box oil and synthetic oil. [53] Many of the same problems associated with natural petroleum exist with waste oil.
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [2] It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm 3. [3]
Rapeseed oil is the preferred oil stock for biodiesel production in most of Europe, accounting for about 80% of the feedstock, [citation needed] partly because rapeseed produces more oil per unit of land area compared to other oil sources, such as soybeans, but primarily because canola oil has a significantly lower gel point than most other ...
Plants use sunlight and photosynthesis to take carbon dioxide (CO 2) out of the Earth's atmosphere to make vegetable oil. The same CO 2 is then put back after it is burned in an engine. Thus vegetable oil does not increase the CO 2 in the atmosphere, and does not directly contribute to the problem of greenhouse gas.
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.
[34] [35] [36] Audi has constructed a carbon neutral liquefied natural gas (LNG) plant in Werlte, Germany. [37] The plant is intended to produce transportation fuel to offset LNG used in their A3 Sportback g-tron automobiles, and can keep 2,800 metric tons of CO 2 out of the environment per year at its initial capacity.
