Correct option is B
To arrange the processes of material flow in an industrial ecosystem logically:
1.
Processing and preparation for finished materials (C) Before any parts are produced, raw materials are processed into forms ready for use.
2.
Forming of finished materials (B) Processed materials are shaped or formed to prepare them for production.
3.
Production of parts for the final product (A) After forming, parts are produced as components for the final product.
4.
Fabrication of the final product (E) Parts are then fabricated into the final usable product.
5.
Recycling components or materials (D) Recycling happens last to ensure sustainability by reusing materials.
Key Points: 1. The Van Krevelen plot is widely used for analyzing the type and maturity of organic matter.
2. The trajectory of a sample on the plot indicates processes such as oxidation, reduction, and decarboxylation.
3. A high H/C ratio suggests a more aliphatic structure, while a lower H/C ratio indicates higher aromaticity or unsaturation.
4. The method helps in classifying organic materials such as lignite, bituminous coal, and anthracite based on their evolution.
Additional Knowledge: · H/C Ratio: A higher ratio indicates a less mature material with more hydrogen content.
· O/C Ratio: A higher ratio reflects a higher degree of oxidation, which can suggest biodegradation or chemical weathering.
· Applications:
· Characterization of biofuels and biomass.
· Geochemical analysis of petroleum and kerogen.
· Studying the transformation of organic matter during pyrolysis.
