2015年3月21日 The yield of coking by-products is one of the key ways to achieve these goals. This review article is focused on history of the by-products such as coal tar, coal
2021年4月6日 In the cupola the only function of the coke is to furnish heat to melt the iron, whereas in the blast-furnace the function is twofold to supply carbon monoxide for
2019年9月16日 It is a porous, carbon-rich solid fuel made by "coking" coal in large “slot ovens” to drive out most of the volatile materials to the atmosphere.
2019年1月1日 This chapter explains the technological principles behind semisoft coking coal utilization from the viewpoint of the mechanism of carbonization and reviews the development and commercialization of technologies, such as briquette blending carbonization process, coal moisture control, dry-cleaned and agglomerated
2021年12月8日 The thermogravimetric and differential thermal analyses (TGA–DTA) were conducted using an SDT Q600 thermal analyzer. The mass of the petroleum coke additive sample was taken within the range of 8.158–12.641 mg. The heating was conducted from 50 to 900 °C at 20 °C/min. The oxidizing atmosphere used was air.
1. Introduction At present, economic and reasonable coal blending is very important in coking production in China. Coking coal enterprises need a series of coal matching tests such as...
The function of the coking unit function is to upgrade the heavy feedstock (s) into more valuable liquid products, and heavy sour crudes have significantly higher amounts of vacuum resid in the feed, the coking unit (especially the delayed coker) is typically one of the most overwhelmed in terms of capacity.
2015年3月21日 Existing energy resources are struggling to cope with the current energy requirements. It is therefore, necessary to increase energy efficiency and reduce greenhouse gases emissions in integrated steel industries. The yield of coking by-products is one of the key ways to achieve these goals. This review article is focused on history of

2013年9月3日 As is widely known, this process makes possible to obtain a coal cake with high density (up to 1080 kg/dm 3,dry base), as long as an optimum moisture content is present in the blend (around...
2018年11月7日 Through optimizing the structure of coal blending system, the accuracy and stability of coal blending process control system can be improved, the coal blending error can be reduced, and the...
2021年4月6日 In the cupola the only function of the coke is to furnish heat to melt the iron, whereas in the blast-furnace the function is twofold to supply carbon monoxide for reducing ore and heat to melt the iron. In the cupola it is desired to produce a minimum of carbon monoxide because the heat required to form this gas is net available for melting.

2020年8月1日 Just over 1000 Mt of coking coal was produced in 2018, accounting for 14 % of world coal production. Generally, coking coal costs more than steam coal and its m arket is limited to the steel industry.
Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, Virginia,
