METHOD OF STARTING PROCESS FOR PRODUCING HYDROCARBONS FROM SYNTHETIC GAS Russian patent published in 2011 - IPC C07C1/04 C10G2/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of starting the process, in stationary state, for producing usually gaseous, usually liquid and optionally usually solid hydrocarbons from synthetic gas, where the said process is a Fischer-Tropsch process involving the following steps: (i) providing an activated catalyst in fixed bed reactor pipes, where the said catalyst is suitable for converting synthetic gas to usually gaseous, usually liquid and optionally usually solid hydrocarbons; (ii) bringing the activated catalyst into contact with a liquid in order to obtain a wet activated catalyst; (iii) bringing the wet activated catalyst into contact with synthetic gas and catalytic conversion of the synthetic gas by carrying out a Fischer-Tropsch reaction at high temperature and pressure to obtain usually gaseous, usually liquid and optionally usually solid hydrocarbons, where the liquid at step (ii) is a hydrocarbon or a mixture of hydrocarbons and is brought into contact with the catalyst at temperature lower than the boiling point of the liquid and pressure between 1 and 50 bar (abs.) (0.1-5 MPa).

EFFECT: use of the method enables to lower catalyst activity, thus preventing excess conversion of synthetic gas when initially brought into contact with the catalyst.
