“…The nitrogen content in UP was relatively low (1.87%), as compared to other seaweed strains such as E. clathrata and S. natans at 3.14% and 3.58%, respectively, though not as low as observed concentrations in Gracilaria cacalia at 0.83% [38] and S. japonica at 0.93% [38]. In biomass pyrolysis, nitrogen leads to formation of NO x precursors (NH 3 and HCN) [41,42]; lower N ratios are therefore favorable. However, UP has a high S ratio, 2.88%, which can cause environmental problems and corrosion in reactors.…”

“…Given the predominance of proteins as the main nitrogen-containing compound in biomass, some researchers [172][173][174][175][176][177] have used amino acids as model compounds to study the behavior of nitrogen during thermal decomposition of biomass. Ren and Zhao [175] studied the pyrolysis and O 2 and CO 2 gasification behavior of phenylalanine, aspartic acid and glutamic acid in a TGA at temperatures ranging from 0 K to1073 K. The distinct structures of these amino acids cause them to behave slightly differently under argon pyrolysis as well as O 2 and CO 2 gasification.…”

“…Ren and Zhao [175] studied the pyrolysis and O 2 and CO 2 gasification behavior of phenylalanine, aspartic acid and glutamic acid in a TGA at temperatures ranging from 0 K to1073 K. The distinct structures of these amino acids cause them to behave slightly differently under argon pyrolysis as well as O 2 and CO 2 gasification. Ren et al [176] found that the structure of the amino acids, the mineral matter content of biomass [178,179], the pyrolysis/gasification condition and the particle size [161,180] affects significantly the fate of nitrogen during pyrolysis of biomass. The thermal decomposition of amino acids and proteins proceeds mainly through dehydration with formation of cyclic amides, with diketopiperazine (DKP) being the common one [172][173][174]177].…”

A Review of Thermal Co-Conversion of Coal and Biomass/Waste

2014

Abstract:Biomass is relatively cleaner than coal and is the only renewable carbon resource that can be directly converted into fuel. Biomass can significantly contribute to the world's energy needs if harnessed sustainably. However, there are also problems associated with the thermal conversion of biomass. This paper investigates and discusses issues associated with the thermal conversion of coal and biomass as a blend. Most notable topics reviewed are slagging and fouling caused by the relatively reactive alkali and alkaline earth compounds (K 2 O, Na 2 O and CaO) found in biomass ash. The alkali and alkaline earth metals (AAEM) present and dispersed in biomass fuels induce catalytic activity during co-conversion with coal. The catalytic activity is most noticeable when blended with high rank coals. The synergy during co-conversion is still controversial although it has been theorized that biomass acts like a hydrogen donor in liquefaction. Published literature also shows that coal and biomass exhibit different mechanisms, depending on the operating conditions, for the formation of nitrogen (N) and sulfur species. Utilization aspects of fly ash from blending coal and biomass are discussed. Recommendations are made on pretreatment options to increase the energy density of biomass fuels through pelletization, torrefaction and flash pyrolysis to reduce transportation costs.

“…It has been postulated that the combined study of biomass and amino acids is the best approach to grasp a more comprehensive mechanism of nitrogen chemistry in biomass components (N-Chemistry) (Becidan et al, 2007). While the pyrolysis of amino acids has been extensively studied, there is very little information on the product distribution from the co-pyrolysis of amino acids with other forms of biomass (Li et al, 2007;Ren et al, 2011). Thus, this study attempts to bridge this gap in a more detailed manner.…”

Phenols from pyrolysis and co-pyrolysis of tobacco biomass components

2015

View full text Add to dashboard Cite

Phenol and its derivatives (phenol, o-, m-, p-cresols, catechol, hydroquinone, methoxy substituted phenols, etc. referred to as phenolic compounds or phenols) are well-known toxicants that exist in the environment and affect both human and natural ecosystems. This study explores quantitatively the yields of phenolic compounds from the thermal degradation (pyrolysis and oxidative pyrolysis) of common tobacco biomass components (lignin, tyrosine, ethyl cellulose, sodium alginate, and laminarin) as well as some mixtures (lignin/tyrosine, ethyl cellulose/tyrosine and sodium alginate/tyrosine) considered important in high temperature cooking, tobacco smoking, and forest fires. Special attention has been given to binary mixtures including those containing tyrosine-pyrolysis of binary mixtures of tyrosine with lignin and ethyl cellulose results in significant reductions in the yields of majority phenols relative to those from the thermal degradation of tyrosine. These results imply that the significant reductions of phenol yields in mixtures are not only dependent upon the mass fractions of the components but also the synergetic inhibition effect of biomass components on the thermal degradation of tyrosine. A mechanistic description of this phenomenon is suggested. The results may also be implied in tobacco industry that the cigarette paper (as ethyl cellulose derivative) may play a critical role in reducing the concentration of phenolic compounds released during tobacco burning.
