The equation has been tested with different lignocellulosic wastes and chars obtained from carbobization at different temperatures. Derivations from the experimental heating values fall in most cases below 2%. A comparison is presented with some equationsfrom the literature based on proximate, ultimate and chemical analysis data. As a general conclusion the equation proposed in this paper leads to comparableand in many cases more accurate predictions of heating valus and has the advantage of being applicable to a wide range of carbonaceous materials, requiring only a simple, rapid and cheap proximate analysis of the samples</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cordero, T</style></author><author><style face="normal" font="default" size="100%">Garcia, F</style></author><author><style face="normal" font="default" size="100%">Rodriguez, J J</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A kinetic study of holm oak wood pyrolysis from dynamic and isothermal TG experiments</style></title><secondary-title><style face="normal" font="default" size="100%">Thermochimica acta</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">heating rates</style></keyword><keyword><style  face="normal" font="default" size="100%">Holm oak</style></keyword><keyword><style  face="normal" font="default" size="100%">isothermal experiment</style></keyword><keyword><style  face="normal" font="default" size="100%">Kinetic model</style></keyword><keyword><style  face="normal" font="default" size="100%">pyrolysis (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">Wood</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1989</style></year></dates><volume><style face="normal" font="default" size="100%">149</style></volume><pages><style face="normal" font="default" size="100%">225-237</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The kinetics of holm oak wood thermal decomposition in a nitrogen atmosphere have been studied using dynamic and isothermal TG experiments. A number of different kinetic models are examined. Discrimination between the first order, second order and spherical symmetry boundary surface reaction models is difficult with the dynamic TG experiments. The isothermal weight loss curves obtained are best described by a first order rate equation.</style></abstract></record></records></xml>
