SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The international Journal of Analytical and Applied Pyrolysis is devoted to the publication of qualitative and quantitative results relating to:
- Controlled pyrolysis (thermal degradation, thermolysis) of chemical materials, including synthetic and natural macromolecules as well as lower molecular weight chemicals.
- Fundamental studies of pyrolysis processes by chemical, physical and physicochemical methods.
- Studies of pyrolysis reaction kinetics, energetics, and mechanisms.
- Technical developments and new instrumentation for pyrolysis techniques in combination with chromatographic or spectroscopic methods.
- Analytical pyrolysis, namely the characterization of a material by chemical degradation reactions induced by thermal energy or by thermally assisted decomposition reactions.
- Environmental, geochemical, biological, medical, and forensic applications of analytical pyrolysis.
- Pyrolysis investigations of energy-related problems, looking for relationships between pyrolysis conditions and product characteristics (i.e. fossil/synthetic fuels, biomass derivatives, thermal catalytic products, coal liquefaction products).
- Automation, optimization and standardization of pyrolysis techniques.
- Computer handling and processing of pyrolysis data, including library filing and retrieval techniques, and computer matching and advanced pattern recognition techniques.
- Studies in high temperature chemistry of synthesis and decomposition reactions.
- Applied pyrolysis, i.e. the use of pyrolysis methods, including thermal cracking, catalytic cracking, hydrothermal treatments, in the disposal of waste materials, in exploiting biomass resources, in fossil fuel transformations for the production of energy, valuable chemicals or engineering materials.
The Journal does not consider studies based solely on:
- thermal analysis, unless combined with the chemical characterisation of the thermal degradation products (e.g. TG-MS, TG-FTIR);
- chemical activation for the synthesis of activated carbons;
- characterisation and application of pyrolysis products, unless clearly related to/aimed at understanding the influence/details of pyrolysis process and conditions;
- theoretical studies, kinetic modelling etc. which are not complemented/validated with experimental data;
- combustion, incineration, unless specifically related to the pyrolysis process.
