Transportation fuels

Still another possibiUty is a marine biomass plantation such as that envisaged for giant brown kelp grown off the California coast and conversion of the kelp to methane in a system similar to that shown in Figure 19. The location of the SNG plant could be either on a floating platform near the kelp growth area or located on shore, in which case the biomass or fuel transport requirements would be different. 

If possible comparisons are focused on energy systems, nuclear power safety is also estimated to be superior to all electricity generation methods except for natural gas (30). Figure 3 is a plot of that comparison in terms of estimated total deaths to workers and the pubHc and includes deaths associated with secondary processes in the entire fuel cycle. The poorer safety record of the alternatives to nuclear power can be attributed to fataUties in transportation, where comparatively enormous amounts of fossil fuel transport are involved. Continuous or daily refueling of fossil fuel plants is required as compared to refueling a nuclear plant from a few tmckloads only once over a period of one to two years. This disadvantage appHes to solar and wind as well because of the necessary assumption that their backup power in periods of no or Httie wind or sun is from fossil-fuel generation. Now death or serious injury has resulted from radiation exposure from commercial nuclear power plants in the United States (31). 

E. Goodrich have burned a 10% tire chip mixture with coal (11—13). Tire grinding size reduction problems and deflvery costs have stymied projects based on combined tire and coal fuel. Transportation of tire scrap can cost 0.05 /kg, exclusive of grinding costs, thus tire-fired boilers are limited to areas with sample scrap tire suppHes, eg, large cities or tire manufacturers. The cost of burning one metric ton of tires per hour in an incinerator was ca 0.20—0.40 per tire in 1974, which increased to 0.35—0.70 per tire in 1987 (14). 

Solar power works well m small tacilities, and it may be comparatively cost-effective when all tactors (transmission, fuel transportation costs, seivice lite, etc.) are taken into consideration. In many instances solar energy is the only viable energy option in the region. 

This is an important fuel transportation, handling, and storage property. It can also be used to help predict contamination with more volatile compounds such as gasoline. 

Water and sediment usually result from poor fuel handling and storage practices. Water and sediment can enter from atmospheric air, through fuel transportation systems, and from blending operations. Corrosion, filter blocking, injection system wear, and deposit formation can result. A listing of some classes of compounds which can be found in middle distillate fuel is provided in TABLE 3-15. 

Flash point is considered to be an important specification for all finished fuels and oils. The flammability and combustibility characteristics of a material are directly related to the flash point. Also, fuel transportation codes require flammable compounds to be appropriately labeled for safety reasons. 

The system uses no fuel or fuel transport, packaging, storage, and disposal systems and needs no intermediate refining facilities and operations. The resulting overhead and financial savings are vast and significant.

Diversity of purveyors, transport system and also diversity of sources contribute significantly to security of energy supply and less dependence on monopoly distributor of fossil fuels and primary energy sources can significantly help economical prosperity of regions without own sources, e.g. South Caucasus, Balkans, Central and East Europe. It also helps to avoid different commercial and/or political pressure on the final consumer. From this reason a possibility of using different ways of fossil fuels transport will be discussed. 

Because of substantial reserves of coal, situated in distant locations from consumers, the limited sources of oil and natural gas, expected growing price of oil and gas a considerable development and progress in the coal pipelining can be expected especially in the USA, in the former Soviet Union and also in other countries in a near future. One of prospective ways of energy transportation, i.e. gas, liquid and also solid fossil fuels transport, seems to be the transport of solidified oil in LNG and pipelining of coal in methanol. 

Fossil fuels have been very important source of energy. It is necessary to pay attention to development of modem, efficient, environmentally friendly and operationally safe way of fossil fuels transport, handling and storage.

A theoretical understanding of the diffusion of hydrocarbons through the porous catalyst layer (see Fig. 2.45) may be obtained by simulations using semi-classical molecular dynamics (as in Fig. 2.3). Such calculations have been performed for the penetration of various hydrocarbons through AljOj catalysts with and without Pt insertions (Szczygiel and Szyja, 2004). As indicated in Fig. 2.46, it is found that fuel transport depends on both cavity structure and the adsorption on internal catalyst walls. 

Fuel transport distance (Table 5) is estimated as a typical average distance considering the Austrian situation. 

The revolution of global energy system often bring us social shock, but the transfer from fossil system to the CO2 recycling system is sufficiently gradual system-transformation using hybrid systems. All the system can provide a liquid fuel transportable globally.
