上海椰清焦炭是烟煤在隔绝空气的条件下，加热到950-1050℃，经过干燥、热解、熔融、粘结、固化、收缩等阶段终制成焦炭，这一过程叫高温炼焦（高温干馏）。由高温炼焦得到的焦炭用于高炉冶炼、铸造和气化。炼焦过程中产生的经回收、净化后的焦炉煤气既是高热值的燃料，又是重要的有机合成工业原料。
Shanghai coconut coke is bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).Made by high temperature metallurgical coke for blast furnace smelting, casting and gasification.Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

焦炭主要用于高炉炼铁和用于铜、铅、锌、钛、锑、汞等有色金属的鼓风炉冶炼，起还原剂、发热剂和料柱骨架作用。炼铁高炉采用焦炭代替木炭，为现代高炉的大型化奠定了基础，是冶金史上的一个重大里程碑。为使高炉操作达到较好的技术经济指标，冶炼用焦炭（冶金焦）必须具有适当的化学性质和物理性质，包括冶炼过程中的热态性质。焦炭除大量用于炼铁和有色金属冶炼（冶金焦）外，还用于铸造、化工、电石和铁合金，其质量要求有所不同。如铸造用焦，一般要求粒度大、气孔率低、固定碳高和硫分低；化工气化用焦，对强度要求不严，但要求反应性好，熔点较高；电石生产用焦要求尽量提高固定碳含量。
Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.Blast furnace with coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.For the blast furnace operation to achieve better technical and economic indexes of metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the nature of the thermal state in the smelting process.Coke in addition to a large number of used in ironmaking and smelting non-ferrous metal (metallurgical coke), also used in casting, chemical industry, calcium carbide and ferroalloy, its quality requirement is different.If foundry coke, general demand big granularity, low porosity, high fixed carbon and sulfur content is low;Chemical gasification with coke, lax to strength requirement, but require good reactivity, high melting point;Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.
