Pyrolysis of jute dust: effect of reaction parameters and analysis of products

Perennial grass (Arundo donax L.) as a feedstock for thermo-chemical conversion to energy and materials

“…In the present investigation, the bio-oil yield was found to be maximum at 500°C for both the heating rate of 10 and 40°C min À1 with increasing temperature from 350 to 650°C. The higher pyrolysis temperatures have been associated with the secondary cracking reactions of the pyrolysis gases resulting in increased gas yield and reduced bio-oil yield (Choudhuri et al, 2014). It was observed that the gas product yield increased with the increase of pyrolysis temperature in both the heating rates.…”

“…It is evident from previous literature that the decomposition of hemicellulose occurs in the temperature range of 220-315°C and that of cellulose occurs at 315-400°C after the initial weight loss due to moisture evaporation at 30-150°C (Yang et al, 2007). Lignin undergoes degradation in the wide temperature range of 150-900°C (Choudhuri et al, 2014). The temperature, in which the maximum rate of weight loss occurs, is given by the DTG curve.…”

“…But when flow rate of the sweep gas was further increased up to 250 ml min À1 , the yield of bio-oil decreased to 19.41%. Thus, highest liquid product was obtained for a sweep gas flow rate of 150 ml min À1 during our study probably due to the minimum secondary reactions of the vapours (Choudhuri et al, 2014).…”

Characteristics and Potential Values of Bio-Products Derived from Switchgrass Grown in a Saline Soil Using a Fixed-Bed Slow Pyrolysis System

“…However, the biochar production fell within the range produced from cellulosic materials, such as corn straw . Moreover, a high pyrolysis temperature may have induced a further decomposition of the bio-oil and biochar, which reduced the yield of both, and increased the syngas production (Choudhury et al 2014). .…”

Pyrolysis of mangaba seed: Production and characterization of bio-oil

“…According to Choudhury et al, (2014) a moisture content below 10% improves the heat transfer during the pyrolysis process. Another factor that affects the heat transfer, calorific power and energy is the ash content (Abraham et al, 2013).…”
