Effective control of carbon number distribution in Fischer-Tropsch Synthesis has been demonstrated with co-fed 1-olefin in a trickle bed reactor. In the presence of suitable n-paraffin solvent, 1-olefin selectivity was as high as 40 mol%, irrespective of C-number. Addition of 1-decene in the n-paraffin solvent could enhance the selectivity of higher hydrocarbons than the added 1-olefin, while suppressing the formation of lighter hydrocarbons especially, methane. Also, conversion of syngas was promoted by added 1-olefin. 1-olefin reacted for hydrogenation, chain propagation or chain degradation in the presence of hydrogen. A new reaction model which explains the C-number distribution has been proposed. Also, the possibility of continuous feed of 1-olefin into the system by recycling solvent was proposed.
