Scientists at the Coal Chemistry Institute of the Hamhung Branch of the State Aacademy of Sciences have developed a method of producing aluminium from carboniferous kaolin.
“The method of producing aluminium from carboniferous kaolin we have developed this time is of great significance in recycling,” said Kwon Son Hwa, key developer and section chief of the institute.
The new method comprises crushing, calcination, iron removing and chemical treatment processes and is very effective in terms of economic utility.
It can extract high-purity aluminium from carboniferous kaolin and quartz, which can be claimed to be a remnant of extraction, and can be used as a raw material for liquid glass by treating it with caustic soda. And ammonium chloride can be retrieved from the liquid which is produced in the course of reaction and treated to be used as a raw material.
Scientists also developed an industrial method of making a catalyst for synthetic fuel.
They established a synthetic fuel process and conducted its trial run successfully for the industrial introduction of the catalyst, providing a scientific guarantee for mass-producing synthetic fuel products with local raw materials.
They also newly added a carbonic acid gas removing process to the gas purification process, one of the main processes in the production of synthetic fuel, to increase the content of effective gas 1.5 times while lowering the amount of materials consumed per unit of product.
