摘要：

Methane (C-1) can be activated by interaction with liquefied petroleum gas (LPG) even at very high C-1 molar fractions in the feed (C-1/(C-1+LPG)=0.85) at temperatures of 450-550(degrees)C, GHSV(LPG)=2240 and 810 ml/g h, over Zn-ZSM-11 (molar fraction Zn2+/(Zn2++H+)=0.86) and total pressure of 1 atm. The isobutane (i-C-4) of LPG could be the main responsible of this interaction. Aromatic hydrocarbons were the main products in the whole range of C-1 molar fractions (0.4-0.85) studied, reaching excellent levels of 10-45%.
