“…When, steam-based gasification reactor with solar energy use drop-tube combination and fixed-bed reactor used for gasification prosess, reaction were performed in the temperature of 1073 -1573 °K, syngas is produced with high quality by H 2 /CO molar ratio = 1.6 and CO2/CO = 0.31, calorific value of 15.3 to 16.9 MJ/kg. Here, enhancement factor (upgrade factor) is 112% [22]. Analysis influence of energy, ecology and dynamics of fluid has studied in fluidized bed gasifier for bagasse [23].…”

Bio-syngas from gasification of sugarcane bagasse is one of the most promising sources for renewable energy. As an agriculture-based biomass, sugarcane bagasse has a high content of moisture (46-52%), fibrous (43-52%) and low bulk density (80-120 kg/m 3 ). This quality of bagasse will tend to initiate agglomeration and cause de-fluidization. It will disturb the gasification process and finally will decrease yield and quality of syn-gas. Its chracteristics in low quality can be improved by pretreatment, i.e., torrefaction process, addressed by slow heating of biomass on wet or dry conditions on atmosphere pressure for 1 hour before it is used as feedstock gasification.This preliminary work features an experimental investigation of torrefaction process of Indonesian sugarcane cane bagasse. Temperature of torrefaction varies from 150, 175, 200, 225, 250 and 300 °C. For bagasse gasification process, the optimum temperature of dry torrefaction is 150 °C. At this temperature, yield of syngas will higher than other torrefaction temperature. Temperature of dry torrefaction will give energy saving opportunities than that's of wet torrefaction (180 °C, 1 hr).Analysis ultimate and proximate also indicate that sugarcane bagasse with temperature torrefaction 150 °C give better result than other torrefaction's temperature in high content of hydrogen and low content of carbon.

“…Solar gasification experimental setups using various carbonaceous materials [13,14] showed that carbon dioxide concentration decreased as much as temperature in the solar reactor increased. In the cited studies, CO 2 was found to account for less than 1% at 1600K, while H 2 production was around 40%.…”

“…A set of empirical equations is used in describing both the chemical reactions and heat-mass transfer phenomena in 1-D, 2D or 3D dimensions. An example of 0D model for steam and solar gasification can be found in [14], where it was used to predict the output of a combined drop-tube and fixed-bed reactor. A 1-D model was proposed for an indirectly-irradiated solar reactor consisting of two cavities separated by a radiant emitter, with the upper one serving as the solar radiative absorber and the lower one containing the reacting packed bed [16].…”

“…Eventually, the various gasification technologies will be analysed "vis-à-vis" obtaining a comprehensive scenario of biomass gasification. The results presented are obtained by simulating the gasification of sugar cane bagasse pellets [19], which are widely used as biomass in other gasification studies ( [14,20]), due to its abundance [21], representing a realistic and proper candidate for industrial scale gasification technologies.…”

Two advanced steam-gasification technologies of biomass, high temperature steam gasification (HTSG) and solar-assisted steam gasification, have been thermodynamically investigated in this work and compared with both conventional auto-thermal gasification and High Temperature Air and Steam Gasification (HTAG). A multi-phase, multi-physics 1D steady-state model has been built up to predict the biomass gasification performance, efficiency, yield and species of produced syngas at varying gasification methods and input parameters. In particular, heterogeneous and homogenous gasification reactions coupled with a radiative transfer were employed in the solar-assisted steam gasification. The results showed that the solar-assisted steam gasification technology demonstrates its potential to produce high quality syngas (nearly 42% H 2 and 35% CO). Moreover, it upgrades the heating value of the product syngas up to 1.4 times more than the original value, due to the additional solar energy induction. Compared with conventional auto-thermal gasification, it was found that the process efficiency can be improved from 65% to 81% if using the HTAG technology and the content of hydrogen in the syngas increased from 30% to 55% if applying HTSG. The modelling results agree considerably with the reported experimental and modelling data in literature, and also able to return a direct comparison of advantage and disadvantage of each gasification method, in terms of syngas quantity and quality.
