Abstract:
1. A method for starting a process for producing normally gaseous, normally liquid and optionally normally solid hydrocarbons from a hydrocarbonaceous feed, which process comprises the steps of: (i) compressing and optionally separating an oxygen containing gas; (ii) partially oxidating 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 converting the synthesis gas of step (ii) at elevated temperature and pressure to obtain the normally liquid and/or gaseous hydrocarbons and steam; and, (iv) using steam or synthesis gas obtained in step (ii) and/or the gaseous hydrocarbons or steam obtained in step (iii) and optionally combusting of hydrocarbons for generating power for providing the pressurized oxygen containing gas for step (i), which method comprises providing steam for the generation of power for starting step (i) for compressing and optionally separating the pressurized oxygen containing gas via a hydrocarbonaceous feed fired boiler until step (iv) takes over for provision of power for step (i) and wherein the steam, synthesis gas or a mixture thereof obtained in starting step (ii) is used in step (iv).
