ABSTRACT:
A method to start a steady state process for producing normally gaseous, liquid and solid hydrocarbons comprises providing a synthesis gas and catalytically converting the synthesis gas into normally gaseous, liquid or solid hydrocarbons. The process involves using at least a portion of the gaseous hydrocarbons produced as a recycle stream to which hydrogen is added prior to its reintroduction into the reactors and as the activity of the catalyst converting the synthesis gas proceeds from start-up towards a steady state, the amount of recycle stream is reduced.
