“…The reaction temperature on the design of the WGSR, varies according with the type of catalyst used e HTC (high temperature catalysts, FeOeCrO based) or LTC (low temperature catalysts, copper based). Lima et al [18] state that, for HTC, increasing reaction temperature increases CO conversion, with best performance in the range from 400 C to 500 C. In the LTC case, reaction only occurs for temperatures starting at~200 C, where conversion rises beyond 90%, decreasing for further increase in temperature. Industrially, to increase overall conversion, a HTS (high temperature shift) followed by a (LTS) low temperature shift reactor is used [22].…”

“…For this reason, generally, the process consists of a high-temperature (HT-WGS) packed bed reactor followed by a low-temperature packed bed reactor (LT-WGS) to achieve high conversion [57]. However, it was found that is it possible to achieve high CO conversion with only one stage, and that is with the HT-WGS packed bed reactor, which is used in this process [56].…”

Biomass is a renewable energy source gaining attention for its potential to replace fossil fuels. Biomass gasification can produce hydrogen-rich gas, offering an environmentally friendly fuel for power generation, transportation, and industry. Hydrogen is a promising energy carrier due to its high energy density, low greenhouse gas emissions, and versatility. This study aims to develop a hydrogen generation plant using a dual fluidized bed gasifier, which employs steam as a gasifying agent, to convert olive pomace waste from the Lebanese olive oil industry into hydrogen. The process is simulated using Aspen Plus and Fortran coding, and it includes a drying unit, gasification unit, gas cleaning unit, steam methane reformer unit, water–gas shift reactor unit, and a pressure swing adsorption unit. The generated gas composition is verified against previous research. Sensitivity analyses are conducted to investigate the impacts of the steam-to-biomass ratio (STBR) and gasification temperature on gas composition, demonstrating a valid STBR range of 0.5 to 1 and a reasonable gasification temperature range of 700 °C to 800 °C. Further sensitivity analyses assess the impact of reformer temperature and the steam-to-carbon ratio (S/C) on the gas composition leaving the steam methane reformer.
