Continuous Homogeneously Catalyzed Hydrogenation of CO2 to Formic Acid in Miniplant Scale

Chemie Ingenieur Technik, EarlyView.
A homogeneously catalyzed multiphase reaction for CO2 hydrogenation to formic acid is demonstrated in a continuous miniplant. The study focuses on catalyst recycling, product stability, and the impact of gas composition on formic acid formation. ABSTRACT A homogeneously catalyzed, high‐pressure hydrogenation reaction to convert carbon dioxide to formic

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

Influence of Piston Elastic Deformation and Structure Design on the Lubrication Characteristics of Piston Pair: Simulation Analysis

Lubricants
Piston pair is a key friction pair of the axial piston pump, but the influence of elastic deformation and the structure design method is not clear. To reveal the real performance of piston pair, a new fluid–solid coupling calculation method is proposed ...
