The potential use of waste feedstocks (beached Posidonia Oceanica and Citrus peels) as fuels for energy recovery by gasification process in a BFB reactor was explored. A direct comparison between two biomasses with a traditional woody biomass (White pine) was carried out through TG-DTG analysis and gasification experiments at 1023 K, 1 bar, Equivalence Ratio equal to 0.3, and different Steam to Biomass inlet ratio (0.5–1.0).

Thermo-gravimetric measurements highlighted that under air-steam gasification conditions Posidonia Oceanica and Citrus peels decompose at temperatures lower than White pine due to the presence of high ash content (9–14 wt%) in the produced bio-chars.

An increasing of syngas and H2 yields, increasing Steam to Biomass inlet stream, was obtained for all the biomasses investigated.

Posidonia Oceanica gasification showed the best yield rates for both syngas (2.64 Nm3/kgbiomass) and hydrogen (0.65 Nm3/kgbiomass) at Steam to Biomass equal to 1 wt/wt, however it exhibited lower Cold Gas Efficiency, Carbon Conversion Efficiency and Lower Heating Value syngas values than Citrus peels gasification in all range of Steam to Biomass ratio.

探索了在BFB反应器中通过气化工艺回收废料（波西多尼亚大洋洲和柑橘皮）的燃料作为能源回收的潜在用途。通过TG-DTG分析和气化实验，在1023 K，1 bar，当量比等于0.3和不同的蒸汽生物量入口比（0.5–1.0）下，通过TG-DTG分析和气化实验，将两种生物质与传统的木质生物质（白松）进行了直接比较。 ）。

热重测量结果表明，在空气蒸汽气化条件下，由于所产生的生物炭中灰分含量较高（9–14 wt％），大洋波西尼亚和柑橘皮在低于白松的温度下会分解。

对于所研究的所有生物量，均获得了合成气和H2收率的增加，从而增加了进入生物质的蒸汽量。

波西多尼亚海洋气化法显示蒸汽到生物质的合成气（2.64 Nm3 / kg生物质）和氢气（0.65 Nm3 / kg生物质）的最佳产率都等于1 wt / wt，但是它显示出较低的冷气效率，碳转化效率和较低的加热在所有的蒸汽与生物质比范围内，合成气值均比柑橘皮气化值高。
