Trans-β-farnesene is produced through fermentation of sugar feedstocks. The pathway offers an alternative to petroleum-based feedstocks derived as by-products of naphtha or ethane cracking.

Abstract:

Butadiene is the main monomer used in modern industrial production of general purpose synthetic rubber. Currently, up to 99 % of butadiene-1,3 is obtained during oil refining, however, due to hydrocarbon reserve depletion, the search for alternative methods for butadiene-1,3 obtaining from renewable resources is an urgent task. One of the most promising renewable sources of raw materials is ethanol. Currently, this process is unprofitable due to low selectivity for the target butadiene. Therefore, in this work, an attempt was made to create a new heterogeneous catalyst that allows increasing t

Abstract:

Propylene is one of the most important feedstocks in the chemical industry, as it is used in the production of widely diffused materials such as polypropylene. Conventionally, propylene is obtained by cracking petroleum-derived naphtha and is a by-product of ethylene production. To ensure adequate propylene production, an alternative is needed, and propane dehydrogenation is considered the most interesting process. In literature, the catalysts that have shown the best performance in the dehydrogenation reaction are Cr-based and Pt-based. Chromium has the non-negligible disadvantage of toxicity

Abstract:

This study examines the evolution and strategic significance of the Methanol-to-Olefins (MTO) process, an autonomous technological innovation that efficiently produces ethylene and propylene derivatives. The process, which emerged during the 1980s, stems from seminal research in methanol conversion methodologies, particularly building upon the 1977 Methanol-to-Gasoline (MTG) protocol. Serendipitous findings regarding hydrocarbon formations within the MTG gasoline fraction catalyzed substantial advancements in methanol conversion technologies. The analysis underscores the pivotal role of the UO

Abstract:

Power-to-Liquid (PtL) plants can viably implement carbon capture and utilization technologies in Europe. In addition, local CO2 sources can be valorized to substitute oil and gas imports. This work’s aim was to determine the PtL efficiency obtained by combining a solid oxide electrolyzer (SOEC) and Fischer–Tropsch synthesis. In addition, a recommended plant configuration to produce synthetic fuel and wax at pilot scale is established. The presented process configurations with and without a tail gas reformer were modeled and analyzed using IPSEpro as simulation software. A maximum mass flow rat
