In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit. The carbon in the coal then react with the oxygen and the water then produces other gases such as carbon dioxide, carbon monoxide, hydrogen and methane. The carbon dioxide from the process is waste and can go to the atmosphere. The other gases can be burned or sent to the next process. Then the second process is after we get the processed and filtered coal, gas or water or carbon dioxide can be added to balance the amount of carbon monoxide and hydrogen.
C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur. The gases released into the atmosphere when a fuel burns may include carbon dioxide, water (vapour), carbon monoxide, sulfur dioxide and oxides of nitrogen. Solid particles (particulates) may also be released. Candidates should be able to relate products of combustion to the elements present in compounds in the fuel and to the extent of combustion (whether complete or partial). No details of how the oxides of nitrogen are formed are required, other than the fact that they are formed at high temperatures.
Year 12 HSC Chemistry Notes (Conquering Chemistry) Module 1 – production of Materials Ethylene, polymers and ethanol * Fossil fuels – energy rich substances formed in the Earth’s crust under intense heat and pressure millions of years ago. Originally remains of marine organisms, they were converted into petroleum that is trapped near the Earth’s surface. Fossil fuels can be extracted and refined to provide energy, and the building blocks of crude oil can be used to create numerous materials for human use e.g. ethylene. * Petroleum – mixture of hydrocarbons, consists of liquid crude oil and gaseous natural petroleum gas.
http://www.enchantedlearning.com The Carbon Cycle: In the atmosphere, carbon is attached to some oxygen in a gas called carbon dioxide. Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.

Radical Chlorination of 1-Chlorobutane. The radical chlorination of 1-chlorobutane was carried out using sulfuryl chloride and azoisobutyronitrile (AIBN). From the reaction there were for possible products which are as follows 1,1-dichlorobutane, 1,2- dichlorobutane, 1,3-dichlorobutane, and 1,4-dichlorobutane. The structures produced from the reaction are as follows; Attached to the four carbons in 1-chlorobutane are hydrogens that can react readily with chlorine, because of its electron withdrawing character. Chemical environment surrounding the carbons are different and therefore affecting the character of the hydrogens attached.
Lab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining Table 1: pH of Water Samples | Water Sample | Initial pH | Final pH (24-48 hours) | Pyrite | 4.5 | 5 | Activated Carbon | 4.5 | 6.5 | Water | 4.5 | 4.5 | POST LAB QUESTIONS 1. Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = Adding pyrite to water it will cause the pH levels to increase. b. Coal hypothesis = If I add activated carbon to the water it will lower the pH level of the water.
When the gas comes out of the ground, it comes out wet. The first stage of the refining process involves on-site heating of the gas to 212 degrees to evaporate any non-methane hydrocarbons and fluids that are mixed into the gas. (Arthur, 2008) The condensate that is generated from this process is then vented into the atmosphere. The condensate often contains the same chemical additives that are added to the well during the fracking process, as well as volatile organic compounds that are naturally occurring in the ground where the gas is stored (Witter,
Well gas & oil gas will be mixed with various other vapors (ethane, propane, methane) that have abundances of Carbon 13 that are similar to each other. Measure the gas for carbon 13 to decide if it is biogenic or thermogenic.
Mercury released in the air gets into the waterways and is accumulated in fishes which are consumed by humans. Since, coal is the most carbon intensive fossil fuel, its burning emits carbon dioxide responsible for greenhouse effect and climate change (Greenpeace,
