A method named acid resolution-elementary analysis was established to determine the quality ratio of hydrogen to carbon of coke on cracking catalyst.

Briquetting experiment with silicon powder and coke fines

This article introduces the briquetting of coke fines using sodium silicate, micro-silica fume and other salt as a binder.

It has been intensified that coke ash can replace a part of coke fines or anthracite coal in sintering, and has a little effect to be neglected on the production, and digests the interior waste resources, and decreases the cost of sinter ore about 56 ten thousand yuan per year.

Preparation of the foundry formed coke by gas coal and coke powder;

Activated carbon was prepared from waste coke powder and the factors affecting the performance of the product were studied by means of orthogonal experiments.

Introduced were the research, pilot plant operation and gasifying test of briquettes made of low cost coke breeze with composite binder as a lump coke alternative to the gasifier.

The result of the study,which was carried out by a Steel Corporation in Japan,on the granulation of coke breeze by using centrifugal rolling type pelletizer is introduced.

The influ-ence of added amount of coke breeze to the maximum reflectivity of vitrinite and maceral composition of the blended coal as well as specifications of product coke as the output of the pilot coke oven were mainly studied in the paper.
