Gansu Olive Leaf Applied Research Breakthrough

A few days ago, the research and industrialization project of the olive-earth leaves completed by the cooperation of the South Anhui Pastoral Olive Science and Technology Development Co., Ltd., the Lanzhou Institute of Chemicals, and the Lanzhou University won the 2013 Gansu Science and Technology. Progress first prize.

The project is funded by the "Science and Technology Supporting Gan" project of the Chinese Academy of Sciences and the "Science and Technology Major Project" of Gansu Province. It aims at the key technologies and industrialization of the separation and preparation of oleuropein and flavonoids, the active ingredients in olive leaves. Carried out basic research, applied research, and industrialization implementation, successfully developed high-quality oleuropein and its core technology “multi-stage series resin column enrichment and separation—differential or binary elution system gradient elution” was successfully developed. Olive flavonoid extract "is transferred industrially. The cooperative enterprise has invested 29 million yuan to build a new production line with an annual output of 50 tons of oleuropein and olive flavonoid extract. Since its production in May 2010, it has achieved significant economic and social benefits. Through the implementation of industrialization, the cost, advanced nature, and environmental protection of the technology are at the leading international level.

Gannan's Longnan is the largest olive cultivation base in China. For a long time, the olive industry has made significant progress in the research and development of cultivation, planting, and especially deep processing of olive oil. However, the research and development of the olive-industrial waste, olive-leaf, is relatively weak. This not only leads to a large number of natural plant resources - the waste of olive leaves, but also causes a series of problems such as environmental pollution and ecological deterioration.

The project aims to make use of modern separation technology, make full use of the olive leaves that are currently discarded as raw materials, and extract and separate active ingredients, oleuropein, flavonoids, and other polyphenol compounds that have important physiological activities and broad market prospects. Waste and treasure, extension of the industrial chain, and the formation of agricultural industries and products with market competitiveness and regional characteristics are in line with the needs of the national agricultural industry policy and strategic development, and have important social, economic, and ecological benefits.

Alloy steel refers to steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the capability is limited. High temperature strength and the corresponding oxidation resistance of heat and strong steel are required. Heat-Resistance Steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace and aviation, petrochemical and other industrial sectors in the work of the high temperature parts. In addition to the requirements of high temperature strength and high temperature oxidation corrosion, sufficient toughness, good shaping and welding are also required according to the different use, as well as a certain organizational stability. In addition,  some new low chromium nickel oxidation are also developed .Heat-Resistance Steel
