TL;DR: In this article, an extractive rich upper phase which varies from 10 to 20% of the total product and a bottom phase closely resembling the normal bark free wood product is composed of components such as fatty acids, fatty alcohols, terpenes, resin acids, and terpenoids.
Abstract: Although high liquid yields of a single phase product can be obtained from bark free “white” wood feedstocks by fast pyrolysis processes, lower yields and a two phase product are obtained from feedstocks containing bark and needles as is commonly found with forestry residues. The liquid yield is thus reduced from levels of 70−75 wt % to those of 60−65 wt %. This will have a significant impact on the economic viability of pyrolysis projects in Scandanavia as forestry residues are a major source of raw materials. The forestry residue product is composed of an extractive rich upper phase which varies from 10 to 20% of the total product and a bottom phase closely resembling the normal bark free wood product. Phase separation occurs due to the higher extractive content of the residues which due to their much lower oxygen phase separate. Extractives are composed of components such as fatty acids, fatty alcohols, terpenes, resin acids, and terpenoids which have lower oxygen content than pyrolysis liquid compound...

TL;DR: The pyrolysis of an epoxy resin and the fire behavior of corresponding carbon fiber-reinforced composites, both flame-retarded with either 10ethyl-9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide or 1,3,5-tris[2]-tris, are investigated in this article.
Abstract: The pyrolysis of an epoxy resin and the fire behavior of corresponding carbon fiber-reinforced composites, both flame-retarded with either 10-ethyl-9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide or 1,3,5-tris[2-(9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-10-)ethyl]1, 3,5-triazine-2,4,6(1H,3H,5H)-trione, are investigated The different fire retardancy mechanisms are discussed, and their influence on the fire properties assessed, in particular for flammability (limiting oxygen index, UL 94) and developing fires (cone calorimeter with different external heat fluxes of 35, 50, and 70 kW m−2) Adding the flame retardants containing 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide affects the fire behavior by both condensed phase and gas phase mechanisms Interactions between the additives and the epoxy resin result in a change in the decomposition pathways and an increased char formation The release of phosphorous products results in significant flame inhibition The fire properties achieved are thus interesting with respect to industrial exploration © 2007 Wiley Periodicals, Inc J Appl Polym Sci 104: 2260–2269, 2007
