Polychlorinated benzene and polychorinated phenol in heterogeneous combustion reactions of ethylene and ethane
Article Abstract:
A study was conducted on the role of short-chain aliphatics as precursors for aromatic compound formation in catalytic processes proceeding combustion. Ethylene and ethane were reacted with HCl/air under heterogeneous combustion conditions between 300-600 degrees centigrade, with SiO2, SiO2/Al2O3 and SiO2/CuP catalyst mixtures subsequently compared with municipal waste incinerator ash. Al2O3-catalyzed reactions exhbited unique ClxBz and ClxPh congene patterns dominated by the dichloro homologue group.

Polychlorinated benzene, phenol, dibenzo-p-dioxin, and dibenzofuran in heterogeneous combustion reactions of acetylene
Article Abstract:
A study was conducted on the heterogeneous combustion reactions of non-chlorinated C2 aliphatics. Acetylene was reacted with HCl/air between 300-600 degrees centigrade. Catalyst SiO2/metal oxide mixtures were then compared with municipal waste incinerator fly ash. Catalytic reaction of C2 aliphatic compounds at 600 degrees centigrade was found to have a significant contribution to the production of chlorination and nonchlorinated aromatic compounds in combustion processes.

Mechanisms of the formation of polychlorinated benzenes and phenols by heterogeneous reactions of C(sub 2) aliphatics
Article Abstract:
A study aimed at investigating the formation of chlorinated benzenes and chlorinated phenols in heterogeneous combustion reactions of nonchlorinated C(sub 2) is presented. Products of incomplete combustion (PICs) bring about the formation of simple aromatic compounds which eventually will turn into polycyclic aromatic hydrocarbons. The mechanism by which the formation of the simple aromatic hydrocarbons, however, has not yet been thoroughly understood.
