Method to start a process for producing normally gaseous, normally liquid an d optionally normally solid hydrocarbons from a hydrocarbonaceous feed, which process comprises the steps of: (i) compressing and optionally separating an oxygen containing gas; (ii) partial oxidation of the hydrocarbonaceous feed at elevated temperature and pressure using the compressed oxygen containing gas of step (i) to obtain synthesis gas and steam; (iii) catalytically convertin g the synthesis gas of step (ii) at elevated temperature and pressure to obtai n the normally liquid and/or gaseous hydrocarbons and steam; and (iv) using steam obtained in step (ii) and/or step (iii) and optionally combusting of hydrocarbons for generating power for providing the pressurized oxygen containing gas for step (i), which method starts with using a hydrocarbonaceous feed fired boiler for providing steam for the generation o f power for step (i) for compressing and optionally separating the pressurized oxygen containing gas until step (iv) takes over for providing the power for step (i).
