A comparative study of by-products yield from coke making processes in a Jenkner apparatus

Abstract

Physico chemical characteristics or the industrial behaviour of any coal is directly controlled by its organic micro components (macerals). The yields of by products during carbonization of coal are affected by organo micro components of different coals and operating parameters, such as, charging technologies, carbonization temperature, particle size, bulk density, etc. In the present investigation, the effects of volatile matters (16.61-36.00%), Ro, avg. (0.80-1.36%), exinite (0.5-4.5%), hydrogen (4.34-5.29%) and nitrogen (1.60-2.18%) content of coal on yield of by products, such as, coke oven gas, coal tar, ammonia, and hydro gen sulphide were studied. The studies revealed that there is a significant difference of the yield of by products for the two different charging technologies. The coke oven gas, coal tar and ammonia yield was lower in stamp charging process as compared to top charging process, whereas, hydrogen sulphide yield followed a reverse trend.

Projeto E Validação De Um Aparato Laboratorial Para Avaliação Dos Rendimentos E Qualidade Dos Produtos Da Coqueificação

“…A retorta Jenkner foi introduzida por Jenkner, Kühlwein e Hoffmann [9] em 1934 com o objetivo de estudar a capacidade coqueificante de carvões minerais, associado a avaliação dos rendimentos dos coprodutos da coqueificação. Ao longo dos anos o aparato Jenkner tem sido utilizado, com pequenas modificações, por diversos grupos de pesquisa para estudo do rendimento destes produtos [10][11][12][13][14]. A Tabela 1 apresenta as dimensões da retorta em sistemas encontrados na literatura.…”
