Abstract
This invention relates to a method to produce carbon microballs from heavy oil residuals. In this method, heavy oil residuals are adopted as raw materials, hydrogen chloride and deionized water are adopted as cleansers and argon is adopted as shield gas. At high temperatures of 1100 minus or plus 10 deg. C, heavy oil residuals undergo chemical and physical conversion, that is, solid state, liquid state, gaseous state and again solid state, and are deposited in the high-temperature region on the inner walls of the quartz tube of tube furnace so as to produce cluster-like spherical black carbon microballs. The microballs have a particle size of 0.4~0.6 mum, an equably spherical shape and is free of byproducts such as carbon fibres and graphite flakes. They are highly purified and no further purification is necessary. No catalyst is adopted in this invention; therefore it has the advantages of concise procedure, simple preparation method, abundant sources and low production cost. Specifically, the carbon microballs are highly purified, with a carbon purity of as high as 99.5%. The yield is also considerable, which can be as high as 70%. The product performs excellent physical and chemical stability and is compatible with kinds of chemical elements. It is widely applicable in the fields of active carbon, graphite and lithium cells, and is a practical method to prepare carbon microballs directly without catalysts.
