The new chemical process can convert the hydrogen sulfide gas in the sewer into hydrogen

An important aspect of the process created by scientists at Ohio State University is that it requires relatively less energy than traditional processes, and the materials required are relatively cheap. The key materials for this process include iron sulfide and trace amounts of molybdenum. Hydrogen sulfide is one of the most harmful gases produced in the industrial production process, and it has considerable harm to the environment and the health of people who encounter it.

Because this gas is harmful, researchers have been working on the process of turning it into something useful. The researchers used a previously created process called chemical cycling. This process adds metal oxide particles to the high-pressure reactor to enable it to burn fuel without the need for contact between air and fuel. When applied to hydrogen sulfide, the process is called SULGEN. However, the research team discovered during the research that the performance of pure iron sulfide did not reach the scale required for industrial processes.

Researchers began to look for other chemicals that could catalyze the reaction, and eventually found that a small amount of molybdenum and iron sulfide can achieve the desired reaction. In addition, both materials are relatively cheap and readily available, making them suitable for industrial-scale conversion processes.

When hydrogen sulfide is converted into hydrogen fuel, it can be used as a substitute for oil and natural gas, which reduces the impact on the environment. However, the project researchers said that it is too early to know whether their process may replace other similar technologies already on the market.
