The resulting coke was characterised by proximate analysis ASTM D 3172-75, grain size ASTM D 4749, sulphur content ASTM D 3177, porosity, calculated by referring to bulk density and true density which were measured in two ways. The first involved a steel cage which was moistened and dried in controlled conditions and the second involved placing coke in a pycnometer and then a water bath ASTM D 167-93.
El coque resultante se caracterizó mediante análisis próximo ASTM D 3172- 75, granulometría ASTM D 4749, azufre ASTM D 3177, porosidad, calculada tomando como referentes a las densidades aparente y verdadera, que son medidas por medio de dos procedimientos; la primera, con una canastilla de acero que se humedece y se seca controladamente; y la segunda, con un picnómetro en el que se deposita coque y agua y se coloca al baño de maría, respectivamente ASTM D 167-93.
