The group of PAN Xiulian and BAO Xinhe have developed a new ZnMnOx-zeolite catalyst which allows for selective syngas conversion to mixed light olefins with a high selectivity. The transformation of syngas to gasoline had a selectivity of 77% at 20% CO conversion and an aromatics content of < 16%. The ratio of isoparaffins to n-paraffins was 15, giving a research octane number of 92 in contrast to about 35~43 obtained by the conventional low temperature Fischer-Tropsch synthesis.
