Utilisation of Liquefied Biomass in Water Co-Electrolysis for the Production of Synthesis Gas

This paper presents a study on the addition of liquefied biomass of different lignocellulosic forest residues as a means to enhance the co-electrolysis process leading to the production of synthesis gas, composed of H2, CO, CO2, and O2, also known as syngas, with the aim of a subsequent conversion into methane and methanol. Tests were made on a 1 kW prototype unit and showed that the use of liquefied biomass clearly enhances the reaction leading to syngas production. The optimisation study performed showed that the best results are obtained with an addition of 2.5% mass of liquefied biomass obtained from Acacia melanoxylon and operating conditions of a pressure of 4 bar gauge and a temperature of 110 °C.
