  • Publication number: 20070087933
    Abstract: A catalyst for the hydroprocessing of organic compounds, composed of an interstitial metal hydride having a reaction surface at which monatomic hydrogen is available. The activity of the catalyst is maximized by avoiding surface oxide formation. Transition metals and lanthanide metals compose the compound from which the interstitial metal hydride is formed. The catalyst's capabilities can be further enhanced using radio frequency (RF) or microwave energy.

  • Publication number: 20050274065
    Abstract: Transesterification, esterification, and esterification-transesterification (both one-step and two-step) for producing biofuels. The process may be enhanced by one or more of the following: 1) applying microwave or RF energy; 2) passing reactants over a heterogeneous catalyst at sufficiently high velocity to achieve high shear conditions; 3) emulsifying reactants with a homogeneous catalyst; or 4) maintaining the reaction at a pressure at or above autogeneous pressure. Enhanced processes using one or more of these steps can result in higher process rates, higher conversion levels, or both.
