Abstract
It was tried to control the carbon number distribution in the Fischer-Tropsch Synthesis (FTS) over supported cobalt catalyst in a trickle bed reactor. When 1-olefin is added to the system, an effective propagation or degradation of C-C chain occurred based on added 1-olefin. Co-fed 1-olefin could enhance the selectivity of higher hydrocarbons than the added 1-olefin, while suppressing the formation of lighter hydrocarbons especially.
