The "ultimate" analysis" gives the composition of the biomass in wt% of carbon, hydrogen and oxygen (the major components) as well as sulfur and nitrogen (if any). The carbon determination includes that present in the organic coal substance and any originally present as mineral carbonate. The hydrogen determination includes that in the organic materials in coal and in all water associated with the coal. All nitrogen determined is assumed to be part of the organic materials in coal.

The "proximate" analysis gives moisture content, volatile content,consisting of gases and vapors driven off during pyrolysis (when heated to 950 C), the fixed carbon and the ash,the inorganic residue remaining after combustion in the sample and the high heating value (HHV) based on the complete combustion of the sample to carbon dioxide and liquid water. Proximate analysis is the most often used analysis for characterizing coals in connection with their utilization.

How do you convert proximate analysis of coal to ultimate analysis?

To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).


What is the difference between proximate and ultimate analysis?

Proximate analysis determines the moisture, ash, volatile matter, and fixed carbon content of a substance, while ultimate analysis determines the elemental composition (carbon, hydrogen, nitrogen, sulfur, oxygen) of a substance. Proximate analysis provides information on the physical and chemical properties, while ultimate analysis provides information on the elemental composition.

Difference between proximate analysis and weende analysis?

Proximate analysis determines the basic chemical composition of a feed sample, focusing on moisture, crude protein, fat, fiber, and ash content. Weende analysis is a specific method of proximate analysis that focuses on determining the crude protein, fat, fiber, and nitrogen-free extract content of feed samples. In summary, while proximate analysis is a broader term, Weende analysis is a specific method within proximate analysis that focuses on certain components.


What is proximate and ultimate analysis of oil?

Proximate analysis of oil provides information on its moisture, volatile matter, fixed carbon, and ash content, helping determine its heating value and combustion characteristics. Ultimate analysis of oil gives the elemental composition in terms of carbon, hydrogen, nitrogen, sulfur, and oxygen content, offering insights into its chemical composition and potential environmental impacts when burned.

How do you identify the grade of coal bitumen vs anthracite from a mine?

Coal is graded based on its carbon content and calorific value. Bituminous coal typically has a higher carbon content and energy value compared to anthracite. One way to identify the grade is to conduct proximate and ultimate analysis tests on the coal samples, which can provide detailed information on its composition and quality. Consulting with a coal expert or using specialized equipment can also help determine the grade accurately.

Importance of proximate analysis?

Proximate analysis is important because it is one of the most effective ways to analyze nutritional value and energy value in food.


Why you do proximate analysis?

We do proximate analysis of the matter to know the nitrogen (protein), oil (fat), mineral, ash content etc to have an idea about the energy contained in that matter.


What are examples of proximate analysis?

Proximate analysis includes determining the moisture content, volatile matter, fixed carbon, and ash content of a sample. It provides important information about the composition and energy content of materials such as coal, biomass, and solid waste. These parameters help in understanding the suitability of a material for various applications, such as combustion or conversion to energy.

Why is vitamins not included in proximate analysis?

because the proximate is just to find the crude one only and they are denatured by heat.
