Abstract
Processes and installations for the production of standard-compliant fuels, preferably gasoline (according to EN 228), diesel (according to EN 590 or EN 15940) and kerosene (according to ASTM D7566 or ASTM D1566), starting from CO2 and H2 by an integrated processing of Fischer-Tropsch raw products via different process steps with recycling of hydrogen or hydrogen-containing gases remaining after the processing into the RWGS before the Fischer-Tropsch synthesis.
Claims18
An installation for the production of standard-compliant fuels, wherein the installation comprises
- A) an optional unit for providing a CO2/H2 mixture
- B) a Fischer-Tropsch synthesis unit comprising or consisting of:
- at least one RWGS (Reverse Water Gas Shift Reaction) stage configured for a reaction of CO2 and H2 to synthesis gas,
- at least one Fischer-Tropsch stage configured for a reaction of CO and H2 in a Fischer-Tropsch synthesis,
- C0) optionally at least one discharge device for product streams originating from the Fischer-Tropsch synthesis,
- C) a processing unit configured for receiving and processing Fischer-Tropsch products discharged from the Fischer-Tropsch synthesis unit, comprising or consisting of
- at least one of the following three subunits:
- i) an isomerization unit,
- ii) a cracking unit
- iii) a hydrogenation unit,
- optionally at least one separation unit,
- at least one feed line for hydrogen,
- one or more discharge lines, each configured for a discharge of a fraction containing a standard-compliant fuel in each case,
- optionally one discharge line for an aqueous phase, and
- at least one discharge line for formed gases comprising hydrogen and C1- to C4-hydrocarbons,
- the at least one discharge line for the formed gases being designed as a recycle line for the gases into the RWGS stage, and wherein
- the installation does not have a purification device for the gases formed in the processing unit which are recycled to the RWGS stage.
A process for the production of standard-compliant fuels, wherein the process comprises:
- A) providing a CO2/H2 mixture,
- B) feeding the CO2/H2 mixture into a Fischer-Tropsch synthesis unit,
- reaction of CO2 and H2 to CO and H2 in a RWGS reaction,
- reaction of CO and H2 in a Fischer-Tropsch synthesis,
- C0) optionally discharging one or more product streams from the Fischer-Tropsch synthesis, and
- C) receiving and processing Fischer-Tropsch products discharged from the Fischer-Tropsch synthesis which were not discharged in C0),
- with the addition of hydrogen
- by
- at least one of the following reactions:
- i) isomerization,
- ii) cracking
- iii) hydrogenation,
- optionally separation,
- discharging of at least one fraction containing a standard-compliant fuel,
- optionally discharging of aqueous phase, and
- discharging of gases formed in processing, comprising hydrogen and C1- to C4-hydrocarbons,
- the discharging of gases formed in processing being carried out as recycle into the RWGS reaction, and
- the gases formed in the processing unit being recycled to the RWGS reaction without purification.
