Estudio de viabilidad de la producción de GTL en Punta Loyola : evaluación privada y social
… a la pro-ducción de combustibles Gas to Liquids (GTL) mediante el pro-ceso FischerTropsch. Para la evaluación privada se utiliza la metodología propuesta por UNIDO, mientras que para el aná-lisis social la de OCDE. Debido a que los procesos FischerTropsch permiten valorizar reservas de gas natural …

General equilibrium impacts of new energy technologies on sectoral energy usage
… examines conditions under which gas-to-liquids (GTL) technology penetration shifts the crude oil-natural gas price ratio. Empirical research finds long-run relationships between crude oil and natural gas prices. Some studies include time trends that steadily evolve the pricing relationship, while …

System model of small-scale gas-to-methanol conversion by engine reformers
… MIT engine reformer-based gas-to-liquids (GTL) systems in the US or India. The system reforms natural gas via partial oxidation into synthesis gas (syngas) in the cylinders of an internal combustion engine, and can significantly reduce capital costs over conventional GTL reforming …

An investigation into the effects of diesel fuel properties on the injection characteristics of a common rail injection system
… fuels were EN590 (a European reference fuel) and GTL (a fuel derived from natural gas). The two injectors were a Bosch solenoid type injector, and a Bosch piezo type injector.

A study of configurational alternatives of a gas-to-liquids process based on Fischer-Tropsch technology
… Gas or Biomass to liquid plants (denoted as CTL, GTL, and BTL, respectively, and collectively referred to as XTL). The economic viability of XTL processes is generally subject to the present price of crude oil and past studies show that traditional refining is generally more economically viable. …

The affine Yangian of gl₁, and the infinitesimal Cherednik algebras
… a recent result of Gautam-Toledano Laredo, see [GTL], to the local setting. We also discuss some aspects of those two algebras such as the degeneration isomorphism, a shuffle presentation, and a geometric construction of the Whittaker vectors.

Economical analysis of a new gas to ethylene technology
… that can convert natural gas into liquids (GTL) or to ethylene (GTE). This technology is a direct conversion method that does not require producing syngas. When selecting a process for ethylene production, the dominant factor is the selection of hydrocarbon feedstocks. Based upon plant …

Hybrid silicon/silicon carbide microstructures and silicon bond strength tests for the MIT Microengine
The Gas Turbine Laboratory (GTL) and the Microsystems Technology Laboratory (MTL) at the Massachusetts Institute of Technology initiated a joint effort to develop a series MEMS-based turbine engines and turbo generators in 1995. This thesis focuses on two independent research topics: first, the use …

Microfabricated refractory ceramic structures for micro turbomachinery
… joint effort between the Gas Turbine Laboratory (GTL) and Microsystems Technology Laboratory (MTL) to develop a MEMS-based micro-gas turbine engine. The thermodynamic requirements of power-generating turbomachinery drive the design towards high rotational speeds and high temperatures. To achieve …

HC-SCR of NO\(_x\) emissions over Ag-AL\(_2\)O\(_3\) catalysts using diesel fuel as a reductant
… fuel reforming of conventional diesel, RME and GTL fuels was conducted for the production of hydrogen (H\(_2\)). The produced H\(_2\) could then be utilized in the combustion process itself or in a HC-SCR reactor, for reduced engine out or tailpipe emissions.

A framework for the evaluation of air pollution caused by motor vehicles.
… people in relevant institutions, including EGA, GTL and ATD, complemented by questionnaires and direct observations. The data collected from the interviews and questionnaires were analysed using Excel and SPSS software.Owing to the lack of data on vehicular emissions in the study area, an …

Particle matter emission control and related issues for diesel engines
… (Rapeseed Methyl Ester (RME) and Gas-to-Liquid (GTL)) were used. They indicated that without any modification to the engine, adding selected alternative fuels, even at a low percentage, could result in a noticeable reduction of the particle numbers, both in the total and the non-volatile parts; …

The engine reformer : syngas production in engines using spark-ignition and metallic foam catalysts
… hard-to-reach gas sources, where gas-to-liquids (GTL) would have the biggest impact on the transportability of that gas. Engines could be deployed at these locations to produce syngas on a small scale and at low cost, as they benefit from the economies of mass production that have been achieved …
