Figure (2) shows a simple diagram of hydrogen production using a partial oxidation process. The syngas is provided at 200C and 20 bar. The use of these reactors would require kinetic analysis, material balance, energy balance and then sizing. The liquid water is converted to steam by exchanging heat with the OBR effluent thereby reducing the amount of utility water required.. 2. The characteristics of different feedstocks (MSWs, wood, green wastes and coffee bean husks) sourced from the literature (BEST Energies Australia Pty Ltd. Report [14], Wilson et al. Hence the general form of the water vapor conversion reaction can be shown as (4): The main role of steam in steam conversion reactions is to transfer the reaction to the production of products, i.e. In the second stage, the synthetic gas produced in the first stage is converted to methanol: After the production of methanol, in the third stage, the methanol is separated from the system and the uncharged gases return to the system in the return stream to reproduce the methanol. Syngas can be obtained from natural gas, coal . Today, with the exception of China, which uses coal to produce methanol, other parts of the world use cheap natural gas as feed to produce methanol. The Global Status of CCS. 1 Energy Requirements 12 3. Methane (the main element of natural gas) participates in the equilibrium reaction with steam and the product of the reaction is mainly hydrogen and carbon monoxide during reaction (3): In addition to methane, other hydrocarbons can also produce hydrogen in response to water vapor conversion. Among the types of reforming used in this process are: Steps such as compression and synthesis of methanol are performed after the reforming operation. https://www.mdpi.com/openaccess.
