Different action of alkali/alkaline earth metal chlorides on cellulose pyrolysis

“…It is well-known that inorganic matter affects the cellulose pyrolysis [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Since, pyrolysis is the fundamental principle of various thermochemical conversion processes of cellulosic biomass, the details of these influences are important for understanding and improve these processes.…”

“…Since, pyrolysis is the fundamental principle of various thermochemical conversion processes of cellulosic biomass, the details of these influences are important for understanding and improve these processes. Demineralized [1][2][3][4][5][6][7], cation-exchanged [6][7][8] and impregnated [4,[9][10][11][12][13] wood or cellulose samples have been used to study the influence. Many studies also have focused on the improvement of the antiflammability of wood and cellulose by impregnating the inorganic matter such as boric acid and phosphate [14].…”

Comparative thermal analysis study of two biopolymers, starch and cellulose

“…The general scheme for thermal degradation has been proposed [4][5][6] to show that combustible volatiles are initially produced. This is an endothermic process but in air, appears as an exotherm because they ignite, this region is termed flaming combustion.…”

Identification of cis‐4,5‐epoxy‐2‐pentenal from pyrolysis of H3PO4‐treated cellulose

“…It is to be notcd that the untreated cellulose could also undergo similar proccsscs lo give I, but its yield would be lower than that from t,hc treated material. 4 Another possibility is t'llat phosphoric acid-t'reated cellulose may degrade to compound I via t'lic formntiorl of levoglucosan which disappears ?s a result of secondary pyrolysis. If this is the case, one would expect to find a large amount of I from the pyrolysis of both levoglucosan and phosphoric acid treated levoglucosan.…”
