Investigation of the Effects of Coke Reactivity and Iron

Both, lowly and highly reactive coke need to be combined with highly reducible iron ore to maximize the gas utilization efficiency. Nevertheless, only appropriately reactive coke can combine with lowly reducible iron ore to obtain an optimal gas utilization efficiency. Hence, it is necessary to select coke with appropriate reactivity, in accordance with iron-ore reducibility, instead of blindly pursuing high-reactivity

The Metal Reactivity Series Compound Interest

This is a case with a common example, iron, the ore of which, haematite, consists primarily of iron oxide. The carbon burns in the furnace to form carbon monoxide; carbon monoxide then reacts with the iron oxide, displacing the iron and forming carbon dioxide. This extraction is possible because iron is below carbon in the reactivity series, and works similarly well for other metals below

Application of the reactivity series of metals in the

Other than tin ore, significant amount of iron ore, copper ore, bauxite and gold are also mined in our country. Besides providing jobs to our people, the local metal extraction industry has contributed greatly to our economy and has supported many local metal-related industries such as the food canning industry, alloy manufacturing and the jewellery industry.

Catalytic reforming of volatiles from co-pyrolysis of

15/02/2021 To better compare the reactivity of carbon-deposited iron ore, the reduction weight loss of three spent iron ores and a mixture of coke and iron ore was prepared in the TGA at a heating rate of 20 °C/min in highly pure argon (99.99%). Note that the coke was obtained from the Linfen Coking Plant in Shanxi Province. The water content in the coke was only 0.94%, the volatile yield was 0.67%, the

Catalytic reforming of volatiles from co-pyrolysis of

Natural iron ore is widely used as a catalytic cracking material in the reforming and upgrading of co-pyrolysis volatiles, where its surface carbon deposition structure can strongly impact the reduction reaction process. Here, the availability of three natural iron ores for the catalytic reforming of volatiles from the co-pyrolysis of lignite and corn straw (CPLC) was investigated to study the
