be easily recovered to produce sponge iron, realizing complete detoxication and zero-emission of chromium residue. Key words: carbon ferrochrome; potassium chromate; two-stage roasting; chromium residue; zero-emission 1 Introduction Chromate compounds are important chemical products, which have been widely used in metallurgy, chemistry, material, leather-making, etc. Normally, the chromate......
was as high as 60.41%. Therefore, it can be easily recovered to produce sponge iron, realizing complete detoxication and zero-emission of chromium residue. Key words: carbon ferrochrome; sodium chromate; oxidizing roasting; chromium residue; zero-emission 1 Introduction Chromate compounds are important chemical products, which have been widely used in metallurgy, chemistry, material and leather-making......
free of carbon emission and produces two useful products at both cathode and anode, promising a zero-emission technology for the extractive metallurgical industry.关键词:......
; 1 Introduction In the wake of the growing demand for carbon- neutral and zero-emission alternative fuels, considerable attention has been paid to transform the biomass-derived compounds into hydrogen-rich gas. Of special interest among such compounds is bioethanol obtained......
for the zero-emission vehicle, one of the main issues to be solved is the storage of hydrogen. After the first stimulating work by BOGDANOVI? and SCHWICKARDI [1], which showed reversible hydrogen storage......
