Advances in Palladium-Catalyzed Carboxylation Reactions

In this short review, we highlight the advancements in the field of palladium-catalyzed carbon dioxide utilization for the synthesis of high value added organic molecules. The review is structured on the basis of the kind of substrate undergoing the Pd-catalyzed carboxylation process. Accordingly, after the introductory section, the main sections of the review will illustrate Pd-catalyzed carboxylation of olefinic substrates, acetylenic substrates, and other substrates (aryl halides and triflates).

Carbon dioxide utilization and circular economy: The world, Russia and the Arctic

Sustainable development of regions, territories, and industrial complexes is becoming increasingly important in the context of global environmental challenges. The practical realization of the sustainability challenges depends more on the implementation of specific technologies, including greenhouse emission mitigation technologies. Today, the development and scaling out of CC(U)S (carbon capture, utilization and storage) technologies seems to be one of the most realistic ways to reduce CO2 emissions. The role of CO2 is changing in the context of circular economy principles, it is no longer considered as industrial waste, but as a valuable resource. The aim of this paper is to analyze and assess the prospects for carbon dioxide utilization, as well as the cost-effectiveness of CC(U)S initiatives (using the example of a CO2-based methanol production project in Iceland) in order to explore the prerequisites and opportunities for the development of such projects in the Arctic. In order to assess the spread of technology worldwide, an analysis of foreign experience in implementing such initiatives is presented, as well as the main promising ways of carbon dioxide utilization and their key features are identified. The economic efficiency of the CO2-based methanol production project (by the example of a commercial project in Iceland) is substantiated. A general vision of the prerequisites and opportunities for the implementation of CC(U)S initiatives in the Arctic regions is presented.

REVIEW OF THE CURRENT INITIATIVES FOR CARBON DIOXIDE UTILIZATION TECHNOLOGIES IN EUROPE AND THE PROSPECTS FOR ROMANIA – PART I

Carbon Capture, Utilization, and Storage (CCUS) technologies comprise a set of proposed technological solutions (i.e. methods, measures, implementations, and policies) that seek to trap carbon dioxide – the main form of carbon carrier molecule responsible for the greenhouse effect, originating from human economic activities, and destabilizing the planetary climate – before its release into the atmosphere. The aim and function of CCUS manifest as either preventive measures that lock carbon dioxide permanently underground or in other suitable media (Carbon Capture and Storage, CCS), or as redirecting processes that feed it back to augmented industrial cycles for manufacturing products with positive financial impacts (Carbon Dioxide Utilization, CDU). Following recent initiatives at the European level and in view of the larger picture unfolding at the global theater, this digest review aims to deliver the main points, considerations, and dynamics that drive and formulate modern CCUS initiatives, focusing more on the recently surfaced CDU front. We will explore proposed pathways for materializing CDU by looking carefully on unfolding examples from such global and European arenas. We will then scrutinize plausible scenarios for transposing CDU to Romania to ask – and hopefully answer – the right questions as to how such scenarios can materialize.
