Liquified petroleum gasoline

Two theoretical products from syngas which are frequently subject to research are ethanol and liquified petroleum gasoline (LPG) [38,39]. In the case of ethanol, direct synthesis from syngas over a rutheniimi catalyst has been demonstrated but selectivity is rather low. LPG is suggested to be produced over methanol, DME, olefins, and hydrogenation to C3/C4 fractions.

The gas-powered drilling and production internal combustion engines can be set up at the manufacturer to operate on gasoline, natural gas, or liquified petroleum gas (LPG). The manufacturer can also set up the engine to operate on all three types of gas fuels. This is accomplished by providing engines with conversion kits that can be used to convert the engine in the field.

Aromatics are important raw materials for the petrochemical industry and they are also used as high octane blending components of gasoline. On the other hand, the availability of liquified petroleum gas (LPG) in the refinery is expected to increase as the FCC units are operated at higher severities in order to maximize the production of butenes, isobutane and propylene. Therefore, there is a clear incentive in converting the low value LPG into aromatics.

Most propane and butane come from petroleum. Propane, known also as LP (liquified propane) gas, is sold as a fuel for cooking and heating. Another use of propane is illustrated in Figure 22-4 on page 700. Butane is used as fuel in small lighters and in some torches. It is also used in the manufacture of synthetic rubber and gasoline.
