Diesel is a light petroleum product, a complex mixture of hydrocarbons (with a carbon atom number of about 10-22), used as fuel for diesel engines. It is mainly composed of diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced through shale oil processing and coal liquefaction, and can be divided into two categories: light diesel (with a boiling point range of about 180-370 â??) and heavy diesel (with a boiling point range of about 350-410 â??). Widely used in large vehicles, railway locomotives, and ships.
The most important use of diesel is for diesel engines in vehicles and ships. Compared with gasoline engines, diesel engines have higher thermal efficiency and lower fuel consumption. Diesel has low energy consumption, so some small cars and even high-performance cars have switched to diesel.

An aldehyde is a class of organic compounds characterized by the presence of a carbonyl group (a carbon atom double-bonded to an oxygen atom) bonded to a hydrogen atom and another organic group. They are often distinguished by their distinct, sometimes pungent, odor. Aldehydes play essential roles in organic chemistry, serving as key intermediates in various chemical reactions and synthesis processes. They are also found naturally in many essential oils and flavors, contributing to the characteristic scents and tastes of numerous fruits, flowers, and spices. Common aldehydes include formaldehyde (used as a preservative and in manufacturing), acetaldehyde (found in alcoholic beverages and responsible for some hangover effects), and benzaldehyde (providing the almond-like aroma in some foods and perfumes).

High purity copper ingot is a very special metal for us, as our activities encompass all aspects of the copper business, ranging from mining through smelting to fabricating. Hereunder, we will examine our achievements in the purification of copper as an example of our purification research. The tables below show analytical results of impurities in the worldâ??s purest copper (6N: 99.9999%Cu). This analysis was conducted by Glow-Discharge Mass Spectrometry (GDMS), which allows microanalysis of all elements. The result indicates the ultra-purity of the copper, proving that the quantities of all elements other than copper are below the detection limit. It is well known that ultra-high-purity metals possess very unique natures sharply different from those of ordinary metals.
High purity copper ingot as adding elements can be directly applied in aviation, space atomic industrial super alloy, and the development of new alloy, as well as the analysis of the standard sample. It can also be through mechanical processing preparation into high purity copper foil shielding materials for atomic reactor.
Aluminum oxide, commonly known as alumina, is a versatile and hard-wearing ceramic material that consists of aluminum and oxygen atoms. It exhibits exceptional hardness and is used in a wide array of applications, including as an abrasive material in sandpapers and grinding wheels due to its ability to cut and shape various surfaces. Additionally, aluminum oxide serves as an insulating material in electronics, a catalyst in chemical processes, and as a refractory material in high-temperature environments such as furnaces and crucibles. Its combination of hardness, high melting point, and electrical insulating properties makes aluminum oxide a crucial material in industries ranging from manufacturing to electronics.
Chlorine is a highly reactive chemical element with the symbol Cl and atomic number 17. It exists as a diatomic gas with a distinct, pungent odor and is widely known for its role as a disinfectant and bleaching agent. Chlorine is extensively used in water treatment to kill bacteria and make drinking water safe, and it plays a crucial role in sanitizing swimming pools. Additionally, it is a key component in the production of a wide range of chemicals, including plastics, solvents, and pesticides. Chlorine's versatile properties and ability to disinfect and oxidize contaminants make it an invaluable resource in public health, industry, and various chemical processes.
