The paper presents the experimental results of Food Court Waste air gasification using a batch reactor. This type of waste is generated mainly in the food court areas of services spaces, shopping centers, airports and malls and is generally composed of paper & cardboard, plastic, organic, wood, metal and glass waste. The process operating parameters were: temperatures between 650°C and 850°C and an equivalent ratio of 0.25 and 0.4 respectively. The study focused on the influence of process parameters on the energy conversion rate considering the cold gas and hot gas efficiency correlated with the feedstock carbon conversion rate. The recorded instantaneous concentrations of sampled gas species were plotted in time dependent graphs for accurate variation curves of gases concentrations. The results can be used to isolate the startup stage of the gasification process and to establish the optimal process parameters for increased overall energy efficiency. In conclusion, considering the current setup, operational parameters and process energy efficiency, the optimal temperature for the air gasification of Food Court Waste is 850ºC with an equivalent ratio of 0.40.

“…Bioenergy is the main alternative candidate that might ensure a low-carbon footprint future. Nowadays, biomass and combustible wastes represent a sustainable option in substituting fossil fuel dependency [5][6][7]. The complex structure and properties allow its conversion into various biofuels in gas, liquid (bio-oil) and solid (bio-char) form [8,9].…”

The study, presented in two parts, puts in discussion the experimental results of low and high temperature pyrolysis on agricultural residues using a tubular batch reactor. During the experiment, nitrogen was used both as reaction environment and gas products carrier. The work focusses mainly on the pyrolysis gas analytical composition resulted from the process. The first part of the research is dedicated to the effect of process low temperature on rape straw pyrolysis. The experiments were conducted at 300°C, 400°C and 500°C to observe the solid – gas transformation at relative low temperatures. The main results revealed that, by balancing the amount of the nitrogen, the rape straw pyrolysis gas distribution varies by average between: 72%-77% CO2, 22%-24% CO, 1%-4% H2. The density of the gas in the devolatilization stage varies by average between 1.6-1.7 kg/m3, while its higher heating value ranges from 4 MJ/Nm3 - 8 MJ/Nm3.

“…There are abundant examples of studies that aim to optimize the gasification conditions using thermal and catalytic treatments in order to improve the gas quality by reducing the tar content in the syngas [10,11], along with the hydrogen content increase and the processing stages reduction. Starting from the analysis of the gasification transitory regime, the process steps can be delimited time approximately, the composition of the gas produced at each stage can be determined, and the efficiency of the material conversion and also the process can be estimated according to the studied parameters [12].…”

Using different gasification agents: air and steam, two types of gasification process were performed into a batch reactor at temperature of 750°C and 850°C and atmospheric pressure. The only difference between of the two compared experimental configurations was represented by the gasification agent used in the process. The amount of oxygen introduced into the reactor for air gasification at an ER of 0.3 was computed. Therefore, in the steam gasification process, the same amount of oxygen was introduced, so establishing an unordinary steam to biomass ratio. In this way, the two processes, air vs. steam gasification, were compared, the rest of the process parameters being kept constant. This paper approaches the transitory regimes (initiation stage) of gasification process in order to observe the influence of process temperature and gasification agent on the process run. According to the experimental results, better gas quality is obtained if steam is used as a gasifying agent, yet the conversion and energy efficiencies decreases. By optimizing time residence in steam gasification, process efficiencies may be increased.
