Evaluation of coal-based FTO synthesis for high-value chemicals Author/Source: Sinochem New Network Date: April 11, 2023 Clicks: 64 Recently, the project \"Development of technologies for coal-based FTO synthesis of high-value chemicals and industrial demonstration\", developed by **Energy Group Ningxia Coal Industry Co., Ltd., Sinochem Synthetic Oil Technology Co., Ltd., and others, passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. The evaluation committee believes that this achievement is highly innovative and has reached an international advanced level. Tailored to the characteristics of Fischer-Tropsch synthesized oil, this technological achievement overcomes technical challenges such as the separation of normal alkanes as a single component and the high-selectivity separation of multiple grades of light white oil. It develops technologies for the high-purity separation of normal alkanes as a single component, as well as a process for the high-selective separation of multiple grades of light white oil with narrow boiling ranges using a single tower. Additionally, a process simulation system for the production of high-purity normal alkanes and light white oil from Fischer-Tropsch synthesized oil has been established. Furthermore, this technology was put into industrial use in September 2020 at Ningxia Coal Industry Company’s 4 million tons per year coal indirect liquefaction project, laying the foundation for the full operation of the facility. It ensured that the product specifications were met, and the comprehensive energy consumption per unit of product as well as the energy consumption per 10,000 yuan of industrial added value were lower than the values specified in the energy assessment criteria, resulting in significant economic, social, and environmental benefits.
