However, Sadowsky et al (ZKG; 5/1997, pg 272) have found that many cement raw materials contain 1.4-6g organic carbon per kg clinker, that these oxidize below 680o C, and that 10-20 % of the oxidation results in CO irrespective of the level of excess O2 (Note that 2g C/kg clinker with 15% conversion yields about 250ppm CO at 5% excess oxygen).
