Biomass gasification is currently a hot research topic. To achieve a high hydrogen content in the product gas, the gasification feedstock used in this study is air‐dried pine woodchips. Experiments are performed in a downdraft gasifier by varying the operation parameters of the particle size (60 mesh, 80 mesh, 100 mesh), temperature point (700, 750, 800, 850, 900°C), and steam‐to‐biomass mass (S/B) ratio (0, 0.7, 1.4, 2.1, 2.8). The main effects of particle size, temperature, and S/B ratio on the composition of the product gas are analyzed to predict the optimal operation parameters of biomass feedstock. For pine woodchip gasification, the optimal particle size is 80 mesh or 0.17 mm, the preferred temperature is 850°C, and the optimal S/B ratio is 1.4. Although there is an error between the experiment and the simulation, the difference is not significant. The Aspen Plus model can provide guidance for the gasification of pine woodchips and can be extended to the gasification of other kinds of biomass.

“…The indication of cracking reaction was the increasing level of hydrogen (Sheeba, Babu, & Jaisankar, 2009). A large amount of yield gas hydrogen maximally produced at the temperature of 1028.6 °C, but the H 2 yield decreased when ER increased.…”

“…Hosoya, Kawamoto & Saka (2007) found that tar from wood polysaccharides underwent secondary reactions including carbonization after condensation with temperatures lower than boiling point in the gasification at 800 °C. Sheeba, Babu, & Jaisankar (2009) found that the increment of gas yield was in line with the increase of temperature. Vaezi, Passandideh-Fard, Moghiman, & Charmchi (2012) concluded that HHV and temperature mainly were effected by biomass oxygen content.…”

This study was to investigate the use of waste mushroom substrate (WMS) material, and waste mushroom substrate pellets (WMSP), with two catalysts (K 2 CO 3 and CaO), as biofuel feed to produce CH 4 in an updraft gasifier. The WMS was made from composted rubber wood chips which had been used for mushroom bed log culture, and pelletizing the WMS (WMSP) to create a biomass with a greater bulk density than the normal WMS. The gasification was determined in the high temperature range of 400-800 0 C by dry fuel feeding at the rate of 25 kg/ha. The results showed that the optimum operation was achieved with WMSP with K 2 CO 3 as the catalyst, at ER = 0.11. The combination of WMSP and K 2 CO 3 produced more CH 4 at 62.2 and 15.27% than single WMS and WMSP, respectively. WMSP with CaO as the catalyst produced 29.65 % less CH 4 than WMSP. Based on gasification equation, CO produced from WMSP was calculated 24.116 % wt, 31.52% wt from WMSP with K 2 CO 3 and 19.21% wt from WMS. The amount of gas produced from the available waste material as the biomass was sufficient to meet all heating requirements of the mushroom production.

“…Large quantities of various biomass wastes are generated in developing countries like India. It was estimated that around 7.5 million tonnes of coir pith is available annually in India which can produce about 129 PJ of heat and 8.7 million tonnes of CO2 was reported by Sheeba et al (2009) [6] . For gasification of coir pith fluidized bed gasification offers significant advantages such as isothermal operation, simple scaling up procedures, high capacities and a good turn down ratio, over other types of gasifier configuration.…”

Biomass characteristics are necessary for the proper selection of the gasification system and to design and evaluate the performance of biomass gasifiers. The coir pith is analyzed for its physical properties, chemical composition and kinetic parameters. The mean particle size of coir pith was found to be 0.551 mm. The relative size range of the coir pith was found to be 0.817. The bulk density, porosity and particle density of coir pith were found to be 87.0 kg m -3 , 71.4% and 305.0 kg m -3 respectively. Coir pith was found to have more volatiles (62.0%) than fixed carbon (26.0%) and ash (12.0%). The elemental carbon and oxygen were found to be 47.1 and 48.3 per cent respectively. The calorific value of coir pith was found to be 18.24 MJ kg -1 . Thermograms obtained for raw coir pith revealed distinct stages of thermal degradation. The ignition temperature was found to be 550 o C.
