The present invention relates to a method for producing liquid or solid hydrocarbons from a synthesis gas via Fischer-Tropsch synthesis which does not carry out a separate reduction pre-treatment for catalyst activation. The method for producing liquid or solid hydrocarbons from a synthesis gas using Fischer-Tropsch synthesis according to the present invention comprises: a first step of applying an iron-based catalyst for the Fischer-Tropsch synthesis in which the number of iron atoms in the ferrihydrite phase fraction equals 10 to 100% and the number of iron atoms in the hematite phase fraction equals 0 to 90%, with respect to 100% of the number of the number of iron atoms, to a Fischer-Tropsch synthesis reactor; and a second step of activating the catalyst for the Fischer-Tropsch synthesis by a synthesis gas which is a reactant under the conditions of the Fischer-Tropsch synthesis and carrying out the Fischer-Tropsch synthesis by means of the activated catalyst for the Fischer-Tropsch synthesis. As such, the present invention is capable of efficiently producing liquid or solid hydrocarbons from a synthesis gas via Fischer-Tropsch synthesis, even without a separate reduction pre-treatment.

Process for the preparation of a polyolefin in a reaction system comprising a reactor comprising a fluidized bed and a distribution plate, product purge bin, and granular feed bin, wherein the process comprises feeding a polymerization catalyst to the fluidized bed, feeding -olefin monomer(s) to the reactor, circulating fluids from the top of the reactor to the bottom of the reactor, withdrawing a stream comprising the polyolefin and fluids from the reactor and passing said stream into the product purge bin, purging the product purge bin with a purge stream comprising an inert gas to obtain a stream comprising a purged polyolefin and a stream comprising fluids, introducing part of the stream comprising fluids back into the reactor, introducing the stream comprising the purged polyolefin into the granular feed bin, and contacting a deactivating stream with purged polyolefin in granular feed bin to obtain the polyolefin free of polymerization catalyst.
