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><issue><style face="normal" font="default" size="100%">11</style></issue></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%">Blasco, J.

H,SO,, H,PO, and ZnCl, have been used as pretreating agents. When using HaSO, the results obtained become quite comparable with those corresponding to the original untreated wood whereas in the cases of H,PO, and ZnCl, significant differences are evident in the distribution functions. Using the activation energy distribution functions, a very good reproduction of the experimental weight-loss curves has been achieved.</style></abstract></record></records></xml>
