Opis:
The article presents our research on applications of fuzzy logic to reduce air pollution by DeNOx filters. The research aim is to manage data on Selective Catalytic Reduction (SCR) process responsible for reducing the emission of nitrogen oxide (NO) and nitrogen dioxide (NO2). Dedicated traditional Fuzzy Logic Systems (FLS) and Type-2 Fuzzy Logic Systems (T2FLS) are proposed with the use of new methods for learning fuzzy rules and with new types of fuzzy implications (the so-called ”engineering implications”). The obtained results are consistent with the results provided by experts. The main advantage of this paper is that type-2 fuzzy logic systems with ”engineering implications” and new methods of learning fuzzy rules give results closer to expert expectations than those based on traditional fuzzy logic systems. According to the literature review, no T2FLS were applied to manage DeNOx filter prior to the research presented here.

Opis:
The subject of this article is to compare the effectiveness of commercial exhaust gas aftertreatment systems such as TWC and GPF with their prototype variant, which is produced on a pilot line that allows the recovery of precious metals. What's more, the said production line allows the manufacture of components compliant with Euro IV, V and VI standards. Depending on the model of the monolith made, it is possible to reduce the consumption of precious metal raw materials by up to 20%, which should be considered a significant result. The article describes in detail the manufacturing process of metal carriers using the mentioned technology. A dynamic engine dynamometer was used for tests verifying the effectiveness of particulate filters, on which the RDE test route covering the area of the Poznan agglomeration was mapped. The tests performed are particularly important, as it should be borne in mind that according to the forecast in 2025, internal combustion engines powered by conventional fuels will account for 85% of all propulsion sources. In addition, the increasing environmental awareness of vehicle users and manufacturers requires solutions to reduce PM emissions into the atmosphere in both mass and number.

Opis:
This paper presents methods of the synthesis and applications of biomimetic catalytic systems produced from molecularly imprinted polymers (MIP). MIPs contain cavities, which are complementary to the imprinted template, thus possess high selectivity and affinity for the molecules resembling template. MIPs have various applications such as: sorption, chromatography, solid phase extraction, drugs transport and catalysis. However, this article is a review of catalytic systems containing in their active sides one of the selected metal ions: copper(II), cobalt(II), zinc(II), iron(III) or nickel(II). Presented catalytic systems are used in hydrolysis, oxidations, hydrogenations and aldol condensation reactions. This review deals with papers published till 2013.

Opis:
Homogeneous catalysts for methane oxidation are of a particular interest from scientific and economic points of view. The results show a great potential for activation and functionalization of CH bonds of unreactive methane. There are still gaps in the knowledge of how to rationally design catalysts for this process. In this paper state-of-the-art. in methane oxidation homogenous catalysis is presented.
