Biomass Pyrolysis in Sealed Vessels. Fixed-Carbon Yields from Avicel Cellulose That Realize the Theoretical Limit

Abstract: In agreement with prior experimental work, thermodynamics predicts differences in the outcome of biomass pyrolysis conducted in sealed, constant-volume systems as opposed to constant-pressure systems. In particular, much higher values of the fixed-carbon yield can be expected in constant-volume systems. Avicel cellulose is known to give very low char and fixed-carbon yields; thus, char and fixed-carbon yields from cellulose have been given primary attention in this work. Our tubing bomb results reveal (i) fixe… Show more

“…Figure 1 shows the contrasting appearances of some CVC charcoals. Signs of a molten phase were evident in chars derived from CVC of birch particles of size <2 mm at a pretest pressure of 0.1 MPa N 2 , a HTT of 400 °C and a heating rate of ~1°C/s, [9] and in chars from the CVC of cellulose grains in a size range from 0.050-0.18 mm, at a pretest pressure of 2.40 MPa N 2 , a HTT of 260 °C and a similar heating rate [8]. To our knowledge, this is the first time molten charcoals have been observed in pyrolysis processes operating at moderate conditions of temperature and slow heating rates.…”

“…Proximate analysis on the final charcoals produced from later CVC experiments on cellulose confirmed the lack of influence of an inert gas pressure on the product yields. [8] Nonetheless, the fixed-carbon contents showed a slight improvement with higher inert pressures. [8] For example, when the initial nitrogen pressure was increased from 0.1 to 4.79 MPa, the fixed-carbon content improved from 54 to 58%.…”

“…[5][6][7][8] Understanding biomass and more specifically lignin reaction mechanisms is also vital for the optimization of bio-carbon production through methods such as hydrothermal carbonization, flash carbonization™ and constant volume pyrolysis. [9][10][11] All these areas of study rely on the control, and thereby understanding, of reaction conditions to tailor product properties while reducing costs.…”
