1. A continuous process for producing hydrocarbons comprising the steps of:
(a) providing an organic starting product,
(b) transferring the organic starting product into a reactor,
(c) heating the starting product to produce a pyrolysis gas,
(d) continuously feeding the pyrolysis gas from the reactor to a two-part or multi-part column to obtain separated liquid and/or semi-solid fractions of hydrocarbons,
(e) obtaining the separated hydrocarbons obtained in step (d),
wherein steps (b) and (c) are executed in the absence of oxygen and under inert gas,
wherein in step (c), the starting product is heated to 400° C. to 600° C., wherein the starting product is a plastic or a mixture of plastics, wherein a second part of the two-part or multi-part column is a fractionating column, and wherein, a flow rate of the pyrolysis gas is lower in a first part of the two-part or multi-part column than in a subsequent second part of the two-part or multi-part column.
