Abstract
A process and apparatus for synthesizing hydrocarbons from synthesis gas is disclosed. The process useful for initial start-up of a Fischer-Tropsch reactor system in a slurry bubble column reactor. Synthesis gas comprising hydrogen and carbon dioxide is reacted to form hydrocarbons. A liquid slurry comprising a start-up composition may include polyalpha olefins, astor wax, waxes, and paraffins. The reaction employs a low superficial vapor velocity, a medium to high catalyst concentration, and relatively mild reactor temperatures as compared to conventional Fischer-Tropsch processes.
