TIGAS features

Topsoe's integrated gasoline synthesis process - TIGAS - converts the synthesis gas to gasoline.

In an improved version of the methanol-to-gasoline process, TIGAS converts synthesis gas into gasoline in a single-loop process, thus eliminating the requirement for upstream methanol production and intermediate storage.

The TIGAS principle

The basic principle in the TIGAS process is the integration of the methanol/dimethylether synthesis and the subsequent conversion into gasoline in a single synthesis loop. 

As the methanol/DME synthesis is very flexible, a variety of synthesis gas compositions may be applied.

TIGAS benefits

The TIGAS process offers a number of benefits:

• elimination of the intermediate production and storage of methanol 
• integrated methanol reaction to form DME immediately 
• improved conversion efficiency reduces steam consumption 
• CO2 removal as well as module adjustment may be carried out inside the synthesis loop, minimising the recycle of unconverted synthesis gas 
• efficient production of high-quality gasoline ready for blending

TIGAS demonstration in Houston

Topsoe's TIGAS process is based on in-house research and development of process and catalysts.

The TIGAS process has been demonstrated at Topsoe's demonstration plant in Houston, Texas applying all process steps involved from natural gas to gasoline with excellent results.
