The Conversion Process

The conversion of biogas into methanol involves several steps that transform biogas into a clean-burning fuel. Let's explore the journey of biogas as it undergoes this innovative conversion process.

1. Purification: The first step in the conversion process is the purification of biogas. This involves removing impurities such as hydrogen sulfide and moisture. Purification is crucial to ensure the quality and stability of the biogas before proceeding to the next step.
2. Methanation: After purification, the biogas enters a catalytic reaction called methanation. In this step, methane, the primary component of biogas, is converted into carbon monoxide and hydrogen. This chemical transformation is essential in preparing the biogas for the final stage of the conversion process.
3. Methanol Production: The final stage involves the combination of carbon monoxide and hydrogen using a catalyst to produce methanol. This conversion process results in the creation of a versatile, clean-burning liquid fuel that can be used in various applications.

The conversion process effectively harnesses the potential of biogas and transforms it into methanol, an environmentally friendly fuel with wide-ranging uses.
