16.1 Introduction

The successful implementation of the gas‐to‐liquid (GTL) fuels in the existing infrastructure has to go through various steps. Since crude‐oil‐derived fuels have been around for much longer, all of its products are well studied in terms of their specifications and safe usage. However, GTL‐derived fuels are relatively newer and have not yet been studied as comprehensively as crude‐oil‐based products. Additionally, GTL‐based fuels offer some challenges that should be overcome before they can be used in the same supply chain for the same transportation vehicles.

The heart of GTL technology is the Fischer‐Tropsch (FT) process. This process converts synthesis gas or syngas (a mixture of hydrogen and carbon monoxide) over a catalyst to produce pure synthetic crude or syncrude. ...
