“…Due to the depletion of the limited petroleum reserves, it is necessary to develop new processes for the production of olens from alternative feedstocks. [6][7][8] Syngas, a mixture of CO and H 2 , can be obtained from various carbon-containing sources, such as coal, nature gas and biomass. 9,10 Syngas conversion provides an alternative nonpetroleum route for olens production.…”

“…Crude-to-chemicals (COTC), i.e. direct production of chemicals and petrochemicals such as olefins and aromatics directly from crude oil, as opposed to via thermal cracking of naphtha/ethane (for olefins) and via traditional refining reforming (for aromatics), is one current industrial tendency [19], together with the development of direct routes for methane to olefins and aromatics [20,21]. Silura OCM (oxidative coupling of methane) process is one example of technology under development attracting increasing interest.…”

There is a demand for new chemical reaction technologies and associated engineering aspects due to on-going transition in energy and chemistry associated to moving out progressively from the use of fossil fuels. Focus is given in this review on two main aspects: i) the development of alternative carbon sources and ii) the integration of renewable energy in the chemical production. It is shown how addressing properly these aspects requires to develop also a) new tools for chemical engineering assessment and b) innovative methodologies for the development of the materials, reactors and processes. This review evidences the need to accelerate studies on these directions, being a crucial element to catalyze the transition to a more sustainable use of energy and chemistry. It is remarked, however, the need to go beyond the traditional approaches, with some examples given. In fact, the presence of radical changes in the way of production is underlined, requiring thus novel fundamentals and applied engineering approaches.

“…Catalytic cracking is a well-known and important refining process that aims to increase the yield of gasoline products [1][2][3][4]. Zeolite catalysts, especially their acidic forms t hat display carboniogenic activity, belong to the most important groups of modern catalysts for petroleum processing and petrochemistry.…”

Up-to-date fluid catalytic cracking catalysts for large-tonnage refining processes work under extremely hard conditions and need to have a high stability to the thermal and steam treatment. Therefore, the purpose of this work was to compare the effect of lanthanum and zirconium additives on the porous characteristics and catalytic activity of the microspherical cracking catalysts in fresh and steamed form that were synthesized based on the Ukrainian kaolin. The synthesized initial sample contained 30% Y zeolite that was transferred to the H-form before the modification by lanthanum and zirconium. The modification led to some decrease in BET surface and samples microporosity, which was substantially intensified after steaming. In the case of zirconium, such a decrease was less than for lanthanum. The effect of the catalysts modification on the vibrations of the structural components of the zeolite lattice was investigated by FTIR spectroscopy. The observed shifts of absorbance frequencies of the bond at 1070 cm -1 , which correspond to the asymmetric vibrations of tetrahedra after corresponding modifications, indicated the isomorphic substitution of the aluminum atoms by zirconium ones. The steamed samples with the zirconium content of 6.5% demonstrated the highest conversion of cumene cracking (an increase by 20-30% as compared with the unmodified sample). Therefore, the modification of fluid catalytic cracking catalysts by zirconium affects both on the adsorption and on the catalytic properties of the steamed samples.
