The interest in Gas-to-Liquid technology (GTL) is growing worldwide because it involves a two-step indirect conversion of natural gas to higher hydrocarbons ranging from Liquefied Petroleum Gas (LPG) paraffin wax. GTL makes possible obtain clean diesel, naphtha, lubes, olefins, and other industrially important organics gas. This article brief review discussing the state-of-the-art GTL, includin...

With the objective of gaining a better understanding of the system design tradeoffs and economics that pertain to biomass-to-liquids processes, 20 individual BTL plant designs were evaluated based on their technical and economic performance. The investigation was focused on gasification-based processes that enable the conversion of biomass to methanol, dimethyl ether, Fischer-Tropsch liquids or...

. There is little doubt that the bulk of the organic matter in meteorites is indigenous, judging from isotopic measurements on C, H, and S (20, 21). Such proof is not available for individual compounds, however, and it is therefore necessary to resort to less direct arguments to rule out terrestrial contamination. We shall briefly review the most reliably established features of organic matter ...

Моделирование процесса синтеза Фишера-Тропша является довольно сложным. Существует большое разнообразие кинетических моделей, которые были разработаны для описания реакции Фишера-Тропша. В данной статье приводится математическая модель процесса, описывающая начальный период расходования СО и образования основных продуктов в присутствии железо-рутений содержащего катализатора на основе сверхсшит...

Fischer-Tropsch synthesis, a major process for converting natural gas to liquid hydrocarbons (GTL) suffers from selectivity limitations. While GTL reactor produces highly useful hydrocarbons in the form of liquid fuels such as gasoline, it also produces low-grade hydrocarbons such as methane. Selectivity refers to the ratio of highly useful hydrocarbons to the total product output. The literatu...

Fischer–Tropsch (FT) synthesis is a process in which synthesis gas (CO/H2) is catalytically converted into hydrocarbons and oxygenates via surface polymerizations. With this process, clean liquid fuels can be made from abundant natural gas reserves and renewable biomass sources, after first being converted to synthesis gas. In the last several decades, FT synthesis has attracted renewed attenti...
