The effect of the weight of tobacco per cigarette (WTC) on the mainstream smoke of reference (R) and commercial (F) cigarettes and the effect of the addition of an SBA-15 catalyst has been studied. The yield of total particulated matter (TPM) obtained from the reference tobacco, with and without catalyst, is decreased as WTC increases, but the results for the commercial cigarettes show a maximum for TPM and CO at the medium WTC value. The highest yields of the different chemical families of compounds appearing in TPM extracted from filters (TPM-F) from F and R cigarettes, and in TPM from the traps after filters (TPM-T) from R, have been obtained at the intermediate WTC, whereas for TPM-F from reference cigarette + catalyst (RC) and TMP-T from F and RC, a decreasing trend as WTC increases is observed. Interesting reductions have been obtained in the presence of catalyst, especially for the carbonyls group in TPM-F and for aromatics in TPM-T.
