Different sizes can be produced according to customers' requirement.
The Introduction of Calcined Petroleum Coke
Calcined Petroleum coke is a by-product of delayed coking unit when the raw oil is cracked at high temperature to produce light oil.The output of petroleum coke is about 25-30% of the raw oil. Its low calorific value is about 1.5-2 times that of coal, ash content is not more than 0.5%, volatile content is about 11%, and its quality is close to anthracite
The Application:
1. Low-sulfur, high-quality cooked coke such as needle coke is mainly used to manufacture ultra-high power graphite electrodes and certain special carbon products; needle coke is an important material for the development of new electric furnace steel making technology in the steel making industry.
2. Medium-sulfur, ordinary cooked coke, used in aluminum smelting in large quantities.
3.High-sulfur, ordinary green coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., and also as a fuel for metal casting, etc.
Semi coke
Production process
Semi coke is a new type of carbon material obtained by pyrolysis of high-quality Jurassic coal blocks abundant in Shenfu coalfield under medium and low temperature conditions to precipitate coal tar and gas.
Characteristics
1. Â High fixed carbon
2. Â High specific resistance
3. Â High chemical activity
4. Â Low ash content
5. Â Low sulphur
6. Â Low phosphorus
7. Â Low Aluminium
8. Low emissions of combustion pollutants
Application
It is widely used in chemical industry, metallurgical industry, gas-making industry, etc.; It is used to produce calcium carbide, ferroalloy, ferrosilicon, silicon carbide, silicomanganese, fertilizer, etc.
It has  became an irreplaceable carbon materials. Semi-coke can completely replace the general coke, and the quality is superior to a number of standards of the national metallurgical coke, coke and ferroalloy coke.
So semi coke has higher application value in the improvement of downstream product's quality level, energy conservation, reduction of production cost, increase production etc..
.
Semi coke also can be used for indoor heat preservation, home cooking, fireplace, small boiler and agricultural production of dry industry.
In addition, the application of semi coke in reducing agents, adsorption materials, blast furnaces and other fields is also expanding. Especially in the carbonaceous reducing agent has unique performance, Â economic advantage is very obvious.
Advantages of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer:
1.Semi Coke could improve the quality of the ferroalloy significantly (especially low aluminum alloy Al2O3 0.1%).
2.Semi Coke could reduce unit electricity consumption significantly (nearly save more than 1000 KWHR, that means 8-10%).
3.Semi coke could lower the cost of raw material. Although the price of semi coke and coke is similar, but it's far cheaper than charcoal and pet-coke.
4.It's very simple to replace coke, pet-coke and charcoal with semi coke. And it's no need to upgrade your equipment, the operation is easy and process is simple.

Coke is mainly used in blast furnace ironmaking and blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony and mercury. It plays the role of reducing agent, heating agent and material column framework.
The use of coke instead of charcoal in ironmaking blast furnace has laid the foundation for the large-scale of modern blast furnace and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes for blast furnace operation, smelting coke (metallurgical coke) must have appropriate chemical and physical properties, including thermal properties in smelting process.
Coke is not only widely used in iron making and non-ferrous metal smelting (metallurgical coke), but also used in casting, chemical industry, calcium carbide and ferroalloy, with different quality requirements.
For example, the particle size and porosity of casting coke are generally high, such as low carbon and fixed coke; Coke for chemical gasification has not strict requirements on strength, but requires good reactivity and high ash melting point; Coke for calcium carbide production is required to increase the fixed carbon content as much as possible used widely in fields of iron and steel making, foundry industry,
the chemicals industry, calcium carbide manufacturing, ferro alloy industry, etc.
Semi Coke, also called gas coke, lam coke, is made from high quality anthracite coal, under a high temperature(1300â??) process. They are widely used for calcium carbide, ferro alloys manufacture or non-ferrous metals smelting, manufacture or other related metallurgical industries, because of its special physical and chemical characteristics: high fixed carbon content, low sulfur and low phosphorus for content.
Metallurgical coke is a general term for blast furnace coke, foundry coke, ferroalloy coke and non-ferrous metal smelting coke. Metallurgical cock and foundry coke are made from a mixing of several kinds of coal, under a high temperature (1300C) process.
Foundry Coke is the main fuel of melting iron in the oven. It can melt the materials in the over, make the iron reach great heat, and keep good air permeability by sustain stock column. Thus, the foundry coke should have the characteristics of big block, low re-activity, small porocity, enough anti-crush strength, low ash and low sulfur.
It is a kind of petrochemical product, whose raw materials is green petroleum coke. It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products..It can also be used as carbon additive in some steel and aluminum plants, another, it is used in refractory, insulation, filler, etc.
The main use of CPC is in the production of anodes for the Aluminum Smelting process. 70 - 80% of CPC is for the Aluminum Industry. The reason for use in the Aluminum Industry is for conductivity. Another use for CPC is TiO2 production which accounts for about 15% of the CPC consumption. The reason for use in TiO2 is for its oxidizing effect. Metallurgical Industry is the remaining major area where CPC is used. The reason for use in Metallurgical Industry is the high Fixed Carbon level (low ash level) and moderate sulfur levels. 300 thousand MT, which supplied more than 50% of the low sulphur grade used in Asia-Pacific, and we have so much advantage in low sulphur and medium sulphur grade CPC. Our quality is steady and excellent, which being the best service. So we have obtained great reputation from the majority of customers.

Definition of Coke
Chengde Wan Yang activated carbon company profile produce coke filter media after a high temperature coking and secondary washing process: high-temperature coking-high-quality anthracite in the isolated air conditions, heated to 950-1050 , after drying, pyrolysis, melting, Kneading, curing, shrinkage and other stages into the wool; second washing-through a strong shaker, the strength of 98% of the wool material in the second washing to remove dust between the particles after sub-screen, Fumigation, drying, dust, packaging, made of high-quality coke. Wan yang coke filter is currently the best commonly used filter material.
Characteristics of Coke
Chengde Wan Yang active coke filter and activated carbon in the main difference is that the structure of activated coke due to the development of the hole in the hole, iodine value decreased, but the value of methylene blue, molasses greatly increased, which showed adsorption Large molecules, long chain organic properties, and because of the existence of resource advantages, resulting in production costs less than 50% of activated carbon, Chengde wan yang activated coke becomes a cost-effective deep-purification of sewage purification materials.
