Fossil fuel processing

In the process of coal hydn nation which is a high-pressure (30 - 70 MPa) catalytic process at a temperature of 500 °C, hydrogen is used to convert coal to gasoline 

The 0x0 synthesis is an exothermal catalytic process in which a H2-CO mixture, as the product gas of the steam reforming process, is used to produce aldehydes which are then hydrided to the respective alcohols. The 0x0 process works at 3 - 30 MPa and 100 -180 °C.

Alicyclic hydrocarbons are saturated carbon chains that form ring structures. Naturally occurring alicyclic hydrocarbons are common (Chap. 1). For example, alicyclic hydrocarbons are a major component of crude oil, comprising 20-67 vol.%. Other examples of complex, naturally occurring alicyclic hydrocarbons include camphor (a plant terpene) and cyclohexyl fatty acids (components of microbial lipids). Anthropogenic sources of alicyclic hydrocarbons to the environment include fossil-fuel processing and oil spills, as well as the use of such agrochemicals as the pyrethrin insecticides (Chap. 1, and references therein). 

The Microtox test has been used for determination of toxicity of wastewater effluents, complex industrial wastes (oil refineries, pulp and paper), fossil fuel process water, sediments extracts, sanitary landfill, and hazard waste leachates [19]. 

Most aromatic hydrocarbons are natural products, but their addition to the environment has increased dramatically through activities such as fossil fuel processing and utilization. Biodegradation of aro-...

The detrimental effects of particulate matter on the atmosphere have been of some concern for several decades. In fact, the total output of particulate matter into the atmosphere has increased in Europe since medieval times (Brimblecombe, 1976), and, although the sources are various, there is special concern because of the issue of particulate matter from fossil fuel use (Cawse, 1982). Species such as mercury, selenium, and vanadium, which can be ejected into the atmosphere from fossil fuel combustion (Kothny, 1973 Lakin, 1973 Zoller et al., 1973), are particularly harmful to the flora and fauna mercury. Thus, there is the need to remove such materials from gas streams that are generated during fossil fuel processing. 

The sunlight/photosynthesis/fossil fuel process has been working at efficiencies well below 1%, thus needing vast land areas - land areas now committed to other uses where they are fertile, or lacking either water or sun elsewhere. There are many ways to approach this problem, PEC being only one, and this is not the place to examine the alternatives. Each has advantages, disadvantages, risks, and state of readiness.

Exposure of Pd-based membranes to non-Ha components of the mixed gas can also lead to performance degradation. Most significant are S-containing compounds that are ubiquitous in fossil-fuel processing streams [17, 34]. Figure 3 (top) shows how a pure-Pd membrane can respond to H2S [26]. In this experiment, a baseline flux of pure Ha was first established across a 25 pm-thick membrane at 350 °C. Then, 1000 ppm HaS was added to the Ha. Immediately upon introduction of HaS, flux...
