Definitions

  • an apparatus comprising: a) an isothermal or adiabatic fixed bed reactor; b) a first condenser; and c) a second condenser, wherein the first condenser and the second condenser are in parallel fluid communication with the isothermal or adiabatic fixed bed reactor via a first connector.
  • Both the wax product and the hydrocarbon product are in gas form in the first product gas.
  • the wax product has a lower boiling point than the hydrocarbon product.
  • the first condenser and the second condenser lower the temperature of the first product gas such that the temperature is below the boiling point of the wax product but above the boiling point of the hydrocarbon products.
  • the wax product liquefies or solidifies in the condenser while the hydrocarbon product remains in gas form, thereby separating the wax product from the hydrocarbon product in the first product gas stream.
  • the hydrocarbon product remains in gas form and exits the condenser, such as the first condenser or second condenser, for further processing.
  • the temperature of the first product gas stream from about 230 °C to about 250 °C.
  • the condenser such as the first condenser or second condenser, lowers the temperature of the first product gas stream such that the temperature is from about 160 °C to about 190 °C.
  • the valve in the second line is closed and the valve in the first line is reopened to redirect the flow of the first product gas stream from the second condenser to the first condenser. This is done after a portion of the wax product in the first condenser that was first collected has been removed to allow more wax product to be collected in the first condenser.
  • the wax product in the second condenser can be removed while the first condenser again is used to continue the process of separating the first wax product from the hydrocarbon product in the first product gas stream.
  • the use of the first condenser and the second condenser can be alternated in this way such that the apparatus can be used in operation continuously.
  • the isothermal or adiabatic fixed bed reactor, first condenser, and second condenser is configured to support a Fischer-Tropsch system on an industrial scale.
  • Aspect 6 The method of any one of aspects 1-5, wherein the first product gas stream before lowering the temperature in step e) has a temperature of from about 230 °C to about 250 °C.
  • Aspect 8 The method of any one of aspects 1-7, wherein the method is continuous.
  • Aspect 9 The method of any one of aspects 1-8, wherein the second product gas stream comprises at least 95 wt % of the hydrocarbon product.
  • Aspect 16 The method of any one of aspects 1-15, wherein the method is performed using an apparatus comprising: a) an isothermal or adiabatic fixed bed reactor; b) a first condenser; and c) a second condenser, wherein the first condenser and the second condenser are in parallel fluid communication with the isothermal or adiabatic fixed bed reactor via a first connector.
  • Aspect 18 The apparatus of aspect 17, wherein the first connector comprises a first line that is in fluid communication with the first condenser, and wherein the first line comprises a valve that configured to regulate the flow of a first product gas stream comprising a wax product and a hydrocarbon product from the isothermal or adiabatic fixed bed reactor to the first condenser.
