The more stringent limitations on the content of sulfur in the petroleum raw materials stimulated in recent years new research dealing with catalytic desulfurization processes. The key trend in the purification of liquid hydrocarbon raw materials is hydrotreatment in which sulfur is removed as hydrogen sulfide, which is then subjected to the Claus process to be converted to elemental sulfur.

With the increasing demands of energy brought by traditional fossil fuels, substitutes for clean and sustainable energy sources has gained a lot research interest. Meanwhile, the enormous amount of greenhouse gases such as carbon dioxide (CO2) emitted into in the atmosphere had caused global warming and climate change. One of the strategies that have been adopted to regulate CO2 in atmosphere is carbon capture and sequestration (CCS), but this kind of isolation of CO2 is commercially not viable due to the high cost involved in the process and also the difficulties involved in the long-term storage of CO2. Another strategy for mitigating CO2 emission is to develop a reliable technology to convert CO2 into low carbon fuels such as methanol, methane, carbon monoxide, and formic acid.

The emergence of quaternary-compound tungsten electrode, which also called WX4, marks a new area of tungsten electrode material, as well as a revolutionary development of the relevant technology, making the reliability and stability of the electrodes further improved. In 2017, based on the Tri-mix composite rare earth technology, China’s researchers continued to break through the technical barriers and are the first one to add four kinds of different rare earths to tungsten, e.g. lanthanum, cerium, zirconium, and yttrium.

Tungsten is a heavy metal exhibits the highest melting point among all the refractory metals. The pure tungsten has a yield strength of 750 MPa and excellent tensile strength of 900 MPa. Due to its amazing strength and hardness, tungsten was widely applied in various fields include defense industry, aerospace industry, and nuclear industry. The conventional alloying method by combining tungsten with other metals is a proven efficient route to enhance its properties to extend its applications.
