| |
| DLG-type catalysts may be used in processing of olefin hydrocarbon from C4 oil liquidized gas, through the chemical reactions such as aromatization, arene alkylation or olefin linkage, to convert these olefin hydrocarbon into pollution-free gasoline with high octane rating with octane rating (RON) reaching 101, sulfur less than 10μg/g and olefin amount less 10%. Catalysts operation time for a single period reaches above six months before the catalyst reproduction. |
