Biomass gasification is the thermo-chemical conversion of organic waste feedstock in a reduced oxygen medium (partial oxidization); while the combustion takes place completely in the presence of stoichiometric oxygen. The common operating temperature for gasification is rather high, commonly varies from 750 °C to 1000 °C, depending on the type of feedstock and operating conditions. The resulting product is syngas, mainly composed by carbon monoxide, carbon dioxide, hydrogen, methane, and solid residues are the by-products (ashes and unconverted biomass). A relevant interest towards SEA0400 gasification produced a huge number of scientific works and perspectives, which are nicely reviewed in the publication by Ref. [27]. Although the gasification is conceptually a high-temperature process, it might be operate at lower temperatures with adapting the effective parameters, operation conditions and alternative design options in the configuration of the reactor. The main concern of this activity is to investigate and apply the low-temperature steam (∼410 °C) generated from the pre-designed solar power plant, which is integrated to the biomass gasification process and drives it efficiently (Fig. 1). According to the authors' knowledge, studies taking into account this aspect of study for low-temperature steam driven solar power plant biomass gasification for 2nd biofuels have not been published in the literature so far. [6] assess a solar-based electricity generation in Chile by CSP, achieved by a Solar Power Tower plant (SPT) using molten salt as heat carrier and store. [12] proposed a study on the gasification process for 3rd generation biofuels. In his work, the design is based on steam gasification of biomass with the heat directly provided by a solar concentrating tower, which provides temperatures over 1000 °C. However, in our work the low-temperature steam (∼ 410 °C) is generated by the concentrated solar power plant and it provides the oxidizing agent for the gasification process.
