19403 results about "Agriculture" patented technology

Agriculture is the science and art of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs, sheep and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture into the twenty-first.

System and method for carbon dioxide capture and sequestration

A method and a system capable of removing carbon dioxide directly from ambient air, and obtaining relatively pure CO2. The method comprises the steps of generating usable and process heat from a primary production process;
    • applying the process heat from said primary process to water to co-generate substantially saturated steam, alternately repeatedly exposing a sorbent to removal and to capture and regeneration system phases, wherein said sorbent is alternately exposed to a flow of ambient air during said removal phase, thereby enabling said sorbent to sorb, and therefore remove, carbon dioxide from said ambient air, and to a flow of the co-generated steam during the regeneration and capture phase, after the sorbent has adsorbed the carbon dioxide, thereby enabling regeneration of such sorbent, and the resultant capture in relatively pure form of the adsorbed carbon dioxide. This process can also be carried out in more efficient form by admixing with the air a minor amount of a flue gas or an effluent gas containing a higher concentration of carbon dioxide than exists in the atmosphere, most preferably following a pre-treatment. The carbon dioxide can be stored for further use, or sequestered permanently following the capture: The adsorbent is exposed to air at substantially ambient conditions and the adsorbent is exposed to the co-generated steam at a temperature in the range of not greater than about 130° C. The system provides the sorbent substrate and equipment for carrying out the above method, and provides for obtaining purified carbon dioxide for further use in agriculture and chemical processes, including manufacturing hydrocarbon fuels, or for permanent sequestration, as needed.

Production of biodiesel from combination of corn (maize) and other feed stocks

A method and system to produce biodiesel from a combination of corn (maize) and other agro feedstock may be simarouba, mahua, rice, pongamia etc. Germ is separated (either by wet process or dry process) from corn, crude corn oil extracted from germ and corn starch milk/slurry is heated and cooked in jet cooker to about 105 degree Celsius, enzymes added to convert starch into fermentable sugars in liquification and saccharification process and rapidly cooled down to about 30 degree Celsius. Simarouba fruits syrup, mahua syrup is mixed with corn starch milk (after saccharification). When yeast is added the fermentation takes place for about 72 hours. Thereafter the fermented wash is distilled to produce ethanol. Water consumed in dry process is very less compared to traditional wet process system. Corn oil and mixture of other oils is fed into transesterification (reaction) vessels where ethanol with catalyst, usually sodium hydroxide is added and reaction takes place for about a period of 2-8 hours. Crude biodiesel and crude glycerin as by-products is produced. Excess ethanol removed by distillation process. Crude biodiesel washed with warm water to remove residual soaps or unused catalyst, dried and biodiesel stored for commercial use. Oil extracted from spent bleach mud (used sodium bentonite), a waste product of edible oil refineries may also be utilized for economical production of biodiesel in combination of corn oil and ethanol.

Method for assimilating remote sensing data of soil humidity in watershed scale

The invention provides a method for assimilating remote sensing data of soil humidity in a watershed scale. The method comprises the following steps of: improving a watershed runoff producing calculation module and developing a distributed hydrological model which is suitable for assimilating remote sensing soil humidity information and describes a soil hydrodynamic process; introducing a particle filtering sequence data assimilation method of information science, and continuously merging and assimilating new remote sensing observation data in a dynamic operation process of distributed hydrological process numerical simulation so as to acquire updated watershed soil humidity assimilated data during sequential assimilation; feeding the updated watershed soil humidity assimilated data back to a distributed hydrological model platform; and gradually estimating the time and space distribution pattern of watershed soil moisture content. Practices prove that by the method, not only high-precision and physically consistent watershed soil humidity data can be provided for research on hydrology, zoology, environment and agriculture, but also the foundation is laid for performing four-dimensional data assimilation processing on soil humidity data of an upper soil layer acquired by using remote sensing retrieval, and improving the precision of the model.
