The tachi has a distinctive style and construction, with a longer handle and a more pronounced curve compared to the katana. The blade is typically made from high-quality steel, with a sharp cutting edge and a strong spine. The tachi was often adorned with elaborate fittings and decorations, reflecting the status and wealth of the samurai who owned it.

In battle, the tachi was a versatile weapon, capable of delivering powerful cuts and thrusts. Its longer length and curved shape allowed for greater reach and cutting power, making it effective against both armored and unarmored opponents. The tachi was also used for ceremonial purposes, such as during weddings and formal events.
Over time, the tachi fell out of favor and was eventually replaced by the katana as the preferred sword of the samurai. However, the tachi remains an important part of Japanese sword history and is highly valued by collectors and enthusiasts for its unique design and historical significance.
A few days ago, the industrialized experimental project for high-efficiency desulfurization developed by the Research Institute of Nanhua University successfully passed the appraisal of scientific and technological achievements by Sinopec Corporation. This breakthrough represents a significant advancement in the field of gas purification technology.
The new technology enhances the traditional tannin solution process by incorporating a high-efficiency desulfurizer. It is designed to remove water gas and convert hydrogen sulfide in the gas stream. The system offers several advantages, including a high absorption rate, excellent purification efficiency, easy sulfur recovery, low chemical consumption, and minimal side reactions. These features make it both environmentally friendly and economically viable.
To date, the technology has been patented with 8 invention patents filed, three of which have already been granted. It has reached an internationally advanced level compared to similar technologies in the industry. The practical application of this technology in the semi-water gas and shift gas desulfurization systems at Nanjing Chemical Industry Co., Ltd. has demonstrated outstanding performance. The desulfurization effect is stable, equipment operation is reliable, sulfur recovery has significantly increased, and hydrogen loss has been effectively reduced. As a result, the technology brings substantial economic and social benefits.
This innovative desulfurization method can be applied across various industries, including coal gas, coke oven gas, refinery gas, biogas, and acid tail gas treatment. Its broad applicability and high efficiency make it a valuable solution for improving environmental protection and resource utilization. With its proven success in real-world applications, the technology is well-positioned for wider adoption and further development in the coming years.
