Fischer tropsch method for offshore production risers for oil and gas wells

An apparatus for producing synthetic hydrocarbons, comprising

• a tubing;
• and
• an annulus,
• wherein the tubing is packed or coated with a Fischer-Tropsch catalyst,
• wherein the tubing is configured such that hydrogen and carbon monoxide are injected into the top of the tubing,
• wherein hydrogen and carbon monoxide travel past the Fischer-Tropsch catalyst to produce synthetic hydrocarbons, and
• wherein heat is rejected as the synthetic hydrocarbons are produced.

A method for producing synthetic hydrocarbon derived products, comprising the steps of:

• injecting a feedstock into a gas lift apparatus;
• and
• forcing synthetic hydrocarbon derived product out of the gas lift apparatus,
• wherein the gas lift apparatus comprises a tubing and an annulus, wherein the tubing further comprises a catalyst, and
• wherein the tubing is configured such that the feedstock travels past the catalyst to form synthetic hydrocarbon derived products.
