Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges.

焦炉煤气，又称焦炉气，英文名为Coke Oven Gas (COG)，由于可燃成分多，属于高热值煤气，粗煤气或荒煤气。 是指用几种烟煤配制成炼焦用煤，在炼焦炉中经过高温干馏后，在产出焦炭和焦油产品的同时所产生的一种可燃性气体，是炼焦工业的副产品。

2013年11月1日 · Coke oven gas (COG) is highly rated as a valuable by-product of coal carbonization to produce coke in the steel industry. Typically, a single ton of coke generates approximately 360 m 3 COG. China annually produces 70 billion N m 3 COG; however, only 20% of the gas produced is utilized as fuel.

Three different process stages – from coal to steel – provide three different gas types: coke gas, blast furnace gas and converter gas. Coke gas is a by-product of industrial coke production …

Properties of coke can be classified into three main categories: q Physical properties, e.g. size distribution, ASTM tumbler strength (stability and hardness) and porosity. q Thermo-Chemical properties, e.g. coke reactivity and coke strength after reaction with CO2.

Coke is a fuel used mainly in blast furnaces to reduce iron oxide to produce iron. It contains carbon, and is similar to coal. It is made from coal by cooking out things that are not carbon. Coke is a product of destructive distillation of coal.

2024年9月1日 · In this study, we integrate a life cycle assessment-economic analysis-scenario analysis model to evaluate various coke oven gas (COG) utilization routes (COGtM: COG-to-methanol, COGtLNG: COG-to-liquefied natural gas, COGtSA: COG-to-synthetic ammonia, and COGtH: COG-to-hydrogen).

2011年2月2日 · Coke-oven gas is a fuel gas having a medium calorific value that is produced during the manufacture of metallurgical coke by heating bituminous coal to temperatures of 900°C to 1000°C in a chamber from which air is excluded.

2013年4月10日 · Raw coke oven gas after treatment in the by-product plant is called clean coke oven gas or simply CO gas. In the by-product coke oven battery the evolved coke oven gas leaves the coke oven chambers at high temperatures approaching 1100 deg C.

Coke oven gas is a gas mixture produced by coking coal during pyrolysis in the carbonization chamber of coking oven. As a coking product, coke oven gas is a combustible gas produced simultaneously along with coke and tar. Broadly speaking, coke oven gas includes crude gas, clean gas, and city gas.
