Author/Source: Coal Chemistry News; Date: April 23, 2020; Clicks: 60. Recently, the invention patent titled “A solvent for preparing high-quality coal-based needle coke, its preparation method, and applications”, filed by Shenmu Coal Chemical Tianyuan Company, received an “electronic patent certificate” issued by the **Intellectual Property Office. The patent of Shenmu Coal Chemical Tianyuan Company, titled “A solvent for preparing high-quality coal-based needle coke, its preparation method, and applications,” was filed as part of the “Research and Development Project on the Preparation of Carbon Materials from 120,000 tons per year of medium- and low-temperature coal tar.” The solvent in question, when mixed with coal tar pitch, results in a light phase that separates more easily from the heavy phase. Moreover, due to the presence of large amounts of light fractions in the solvent, it is easier to separate this solvent during vacuum distillation, which reduces the energy required for its recovery, increases the recovery rate of the solvent, lowers the production costs of coal-based needle coke, and also contributes to environmental protection. To date, Shenmu Coal Chemical Tianyuan Company has filed a total of 6 patents under the \"120,000 tons per year research and development project on the production of carbon materials from medium- and low-temperature coal tar\", and 2 invention patents along with 1 utility model patent have been granted. It is understood that in order to significantly increase the added value of its products and pursue a path in high-end, precision chemical manufacturing, Tianyuan Company began research and development on new carbon materials derived from medium- and low-temperature coal tar in 2017, and achieved tangible results. In June 2018, the preliminary and design work for the research and development project on the production of carbon materials from 120,000 tons per year of medium- and low-temperature coal tar was officially launched. The research and development project for the production of carbon materials from medium- and low-temperature coal tar at a capacity of 120,000 tons per year, carried out by Shenmu Tianyuan Chemical Co., Ltd. under Shaanxi Coal and Chemical Industry Group, is located in the Jinjie Industrial Park in Shenmu. The company already has a facility for the lightweight processing of medium-temperature coal tar with a capacity of 500,000 tons per year on site. The project covers an area of 5,000 m2, with an investment of 293.01 million yuan, of which 1.8 million yuan is allocated to environmental protection measures, accounting for 0.61% of the total investment. The main process units of the proposed project include tank areas, coal tar pre-distillation, and asphalt pretreatment.
