Catalysts speed up chemical reactions

Advanced cobalt-based synthesis catalysts developed by Shell Catalysts & Technologies are crucial for efficient, large-scale conversion of natural gas to liquid fuels and other products. Each catalyst is as small as a grain of rice, and just 150 grams of them have the surface area of a football field.

Huge volumes of gas are exposed to the catalysts’ chemically treated surface, which maximises the rate of chemical GTL-reactions. The vast surface area is the result of the catalysts' many nano-sized inner channels, which make them highly porous.

Every few years, the cobalt inside used catalysts is reclaimed to make new ones.

GTL Fuels

Shell GTL Fuel is an alternative fuel for use in diesel engines, which can lower local emissions (e.g. particulate matter, NOx, hydrocarbons and carbon monoxide).?

It can be used in existing heavy-duty diesel vehicles without modifications, allowing for easy switchover from diesel fuel with no infrastructure investment required.[1] Shell GTL Fuel is already in daily use with commercial fleets in Germany and the Netherlands.

Shell GTL Fuel has broadly similar physical characteristics to crude diesel derived from crude oil, but it has a much higher cetane number, a higher mass calorific value, lower levels of sulphur and aromatics, and a lower density.

GTL Kerosene

GTL Kerosene

GTL Kerosene is a synthetic product made from natural gas rather than crude oil, which can be used in aviation and other applications. GTL Jet Fuel is a blend of GTL Kerosene and conventional crude oil-derived standard jet fuel. It is approved for most aviation use at concentrations up to 50% blended with conventional oil-based kerosene (standard Jet A1).?

Compared with conventional oil-based kerosene, GTL Kerosene produces virtually zero sulphur dioxide emissions and lower particulate emissions. This means that once blended with conventional jet fuel to create GTL Jet Fuel, it can be attractive to airlines and airport authorities keen to improve local air quality at busy airports by reducing local emissions.

In addition Shell GTL Kerosene has excellent combustion properties with low emissions, making it suitable as lamp oil and fuel for use in greenhouses due to its high smoke point. It can also be used as a feedstock in manufacturing the raw ingredients for detergents, and it makes a good solvent for metal cleaning and dry cleaning.

GTL Paraffin

GTL Normal Paraffin

GTL Normal Paraffin is an alternative feedstock for detergent production replacing normal paraffins from oil-based kerosene. Also known as light detergent feedstock (LDF) and heavy detergent feedstock (HDF), these products are used in making washing up liquids and PVC plasticisers.

GTL Drilling Base Fluids

GTL Naphtha

GTL Naphtha

GTL Naphtha is an alternative high-quality feedstock for chemical manufacturing that makes the building blocks for plastics. It offers superior yields of ethylene and propylene over conventional naphtha.

As a synthetic product, GTL Naphtha has a consistent quality and contains no sulphur and heavy metals, which makes it cleaner. It is also more paraffinic than light high paraffinic naphtha while giving better lower olefins yields.?

GTL waxes

GTL Waxes

GTL Waxes are found in our speciality Shell GTL Sarawax range, suitable for applications ranging from hot melt adhesives, PVC lubricants, printing inks, rubber and tyres to candles, personal care and packaging material. GTL waxes comply with the United States Food and Drugs Administration regulations for indirect food contact applications.

Shell GTL Waxes are odourless and have an opaque white appearance and produce colour brilliance with minimum colouring agents. They also have high purity and consistent properties which make them ideal for automated and precision industrial applications. Sharp melting and cooling and low viscosity improve application speed.

GTL Phase Change Material

GTL Phase Change Material

Shell GTL Phase Change Material (PCM) under the brand name Shell GTL Saraphaez is a specialty wax which absorbs or releases its relatively large latent heat when it changes phase (between solid and liquid).

In building materials, it helps to maintain a comfortable indoor temperature and minimises use of active air-conditioning/heating by the release and absorption of latent heat. Other applications include clothing fabric, batteries, industrial and consumer heat storing and insulation.
