  • Patent number: 11859145
    Abstract: An improved alkaline pretreatment of biomass is provided that is a single-stage, two oxidant alkaline oxidative pretreatment process. The process uses a homogenous catalyst with at least two oxidants (Hydrogen peroxide and enhanced levels of oxygen) in an alkaline environment to catalytically pretreat lignocellulosic biomass in a single-stage oxidation reaction. The provided single-stage alkaline-oxidative pretreatment improves biomass pretreatment and increase enzymatic digestibility to improve the economic feasibility of production of lignocellulose derived sugars.

  • Publication number: 20200332376
    Abstract: An improved alkaline pretreatment of biomass is provided that uses a homogenous catalyst with one or more metals and metal coordinating ligands, wherein the homogeneous catalyst is used with at least two oxidants in an oxidation reaction to catalytically pretreat lignocellulosic biomass. In one embodiment, hydrogen peroxide and oxygen are utilized as co-oxidants during alkaline-oxidative pretreatment to improve biomass pretreatment and increase enzymatic digestibility. In one embodiment, the homogenous catalyst is copper (II) 2,2?-bipyridine (Cu(bpy)). Related methods are also disclosed to improve the economic feasibility of production of lignocellulose derived sugars.

  • Patent number: 8694356
    Abstract: Augmenting service oriented architecture (‘SOA’) governance maturity including receiving an evaluation of the maturity of the governance of the SOA; identifying, for each governance capability in dependence upon the evaluation of the maturity of the governance capability, one or more predefined risks to the SOA; establishing, for each governance capability in dependence upon the predefined risks to the SOA, a risk value representing the severity of the predefined risks; selecting, for each governance capability in dependence upon the evaluation of the maturity of the governance of the SOA and the predefined risk value, one or more governance work products; and communicating to predetermined stakeholders in the SOA the one or more predefined risks to the SOA identified for each governance capability, the risk value established for each governance capability, and the governance work products selected for each governance capability.
