“…In order to establish the thermodynamic parameters of the pyrolysis process, a number of detailed thermal studies have been carried out on a variety of macroal gae species [69,78,[116][117][118][119][120][121], as well as on a set of model carbohydrate compounds [110]. In both cases, the decomposition was found to take place in three distinct Perspective Rowbotham, Dyer, Greenwell & Theodorou stages: dehydration, followed by the main pyrolysis/ devolatilization and, finally, a slow decomposition step [69,78,116,118,120].…”

“…In addition, the pyrolytic gas can be used as a combustible fuel, while the char has various applications including fertilizer, activated carbon material (Bird et al, 2011) and carbon sequestration (Bird et al, 2011). Algal biochar has lower carbon content, surface area and cation exchange capacity compared to the lignocellulose biochar, but it has higher content of nitrogen, ash and inorganic elements (P, K, Ca and Mg) and also higher pH (Zhao et al, 2011).…”

“…Developing such insights for macroalgae feedstocks where the metal concentrations can be remarkably high (of the order of 10-20% of the dry weight [12]) is imperative. Indeed, significantly, few of the investigations to date feature a full analysis of the metal profile in the feedstock [28][29][30]. However, it should be noted that these types of studies are complicated because samples of metal-free macroalgae are not readily accessible as metal ion extraction (by acid washing for example) typically results in significant alteration of the biomolecular matrix that is under investigation [31,32].…”

Copper(II)-mediated thermolysis of alginates: a model kinetic study on the influence of metal ions in the thermochemical processing of macroalgae

Thermochemical processing methods such as pyrolysis are of growing interest as a means of converting biomass into fuels and commodity chemicals in a sustainable manner. Macroalgae, or seaweed, represent a novel class of feedstock for pyrolysis that, owing to the nature of the environments in which they grow coupled with their biochemistry, naturally possess high metal contents. Although the impact of metals upon the pyrolysis of terrestrial biomass is well documented, their influence on the thermochemical conversion of marine-derived feeds is largely unknown. Furthermore, these effects are inherently difficult to study, owing to the heterogeneous character of natural seaweed samples. The work described in this paper uses copper(II) alginate, together with alginic acid and sodium alginate as model compounds for exploring the effects of metals upon macroalgae thermolysis. A thermogravimetric analysis–Fourier transform infrared spectroscopic study revealed that, unusually, Cu 2+ ions promote the onset of pyrolysis in the alginate polymer, with copper(II) alginate initiating rapid devolatilization at 143°C, 14°C lower than alginic acid and 61°C below the equivalent point for sodium alginate. Moreover, this effect was mirrored in a sample of wild Laminaria digitata that had been doped with Cu 2+ ions prior to pyrolysis, thus validating the use of alginates as model compounds with which to study the thermolysis of macroalgae. These observations indicate the varying impact of different metal species on thermochemical behaviour of seaweeds and offer an insight into the pyrolysis of brown macroalgae used in phytoremediation of metal-containing waste streams.
