Fuel additives have sparked interest due to the demand for ultra-low sulphur diesel fuel and the high cost of additions. It is the cleanest diesel fuel available today, and it is used in automobile engines all over the world. To meet the criteria of the specification, cetane improver (CI) and lubricity additive (LA) are regularly added to ultra-low Sulphur diesel (ULSD) fuel. Additives are always more expensive than diesel fuel, and their price is determined by their performance. Additives can sometimes have unintended consequences on the fuel's other qualities. As a result, when employing additions, the performance of the additive as well as its negative impact on other fuel qualities are critical considerations.
The Nayara Energy Research and Development team conducted a laboratory size experiment to assess the performance and side effects of several ULSD fuel additives, such as cetane improvers and acid and ester based lubricity additives.
The following are the aspects of ULSD fuel that have been investigated:
1) Use different cetane improvers.
2) The effectiveness of cetane improvers.
3) The effect of a cetane improver on ULSD fuel lubricity.
4) Lubricity additive performance in the presence of cetane improvers.
5) The impact of a cetane improver on twenty other diesel fuel characteristics.
6) A two-month stability research was conducted on critical Diesel fuel qualities.
The findings of an experimental investigation are both fascinating and valuable. The findings clearly show that cetane improvers can degrade fuel lubricity and interfere with the efficacy of lubricity additives. 2EHN raises the total nitrogen content of the fuel, resulting in more NOx being produced during combustion. When compared to acid-based lubricity additives, ester-based lubricity additives perform better. As a result, the research will be extremely valuable to petroleum refineries in determining the optimal chemicals and combinations of additives to utilise in the production of ULSD gasoline. Manufacturers of additives for ULSD fuel will also need to design and create the best additives. This experimental investigation will be useful to research and analytical scientists in evaluating the performance of additives and their adverse effects. It will give consumers with information on alternative additives and improvers.
The findings of numerous laboratory experiments, the performance assessment data of cetane improvers, the adverse effects of cetane improvers, and the performance of lubricity additives (acid and ester based) in the presence of cetane improvers are all included in the study report. The results of a two-month stability trial and information from a literature review are also included in the study report.Author(S) Details
