Catalysis Research of Relevance to Carbon Management: Progress, Challenges, and Opportunities

TL;DR: The goal of the "Opportunities for Catalysis Research in Carbon Management" workshop was to review within the context of greenhouse gas/carbon issues the current state of knowledge, barriers to further scientific and technological progress, and basic scientific research needs in the areas of H2 generation and utilization.
Journal ArticleDOI

Catalytic synthesis of α-methylene-γ-valerolactone: a biomass-derived acrylic monomer

TL;DR: In this article, a two-step process for the synthesis of MeMBL from a biomass-derived starting material, levulinic acid, is described, where the first step is a high-yield hydrogenation of formaldehyde with GVL in nearly quantitative yield using a Ru/C catalyst.
Patent

Phosgene manufacturing process

TL;DR: In this article, a process for producing phosgene is disclosed which involves contacting a mixture comprising carbon monoxide and chlorine (e.g., at about 300 °C or less) with carbon which has a micropore to macropore ratio of 3.5 or less; has a high degree of oxidative stability (i.e., loses about 16 % of its weight, or less, in the WVC Temperature Test as defined herein); and has a minimum surface area of at least 10 m2/g.
Patent

Continuous process for the preparation of polytrimethylene ether glycol

TL;DR: In this paper, a continuous process for the preparation of polytrimethylene ether glycol from 1,3-propanediol reactant is presented. But this process is not suitable for polyethylene glycol.
Patent

Gas-phase fluorination process

TL;DR: An improved gas-phase process for the manufacture of 1,1,1-trifluorodichloroethane and/or 1, 1 1/2-tetrafluorochloroethylene by contacting a suitable tetrahaloethylene with hydrogen fluoride in the presence of a selected metal in combination with a high fluorine content aluminum-containing compound is presented in this article.
