  • Patent number: 6763309
    Abstract: A catalyst development engine (CDE) provides a rapid approach to the rational development of scalable heterogeneous catalysts and of high-performance solid materials. The CDE includes three main components: the testing cycle, the knowledge cycle, and the knowledge repository or database. The knowledge cycle generates working hypotheses relating performance to key catalyst properties via machine learning methods, computation chemistry and micro-kinetic modeling. Such an approach accelerates development and scale-up of new materials without the impediments introduced by conventional combinatorial approaches based on randomly selected materials.

  • Patent number: 6727096
    Abstract: Computer programs and computer-implemented methods for monitoring the progress and properties of parallel chemical reactions. The invention repeatedly receives a measured value or values associated with the contents of each of a plurality of reactor vessels and displays the measured over the course of a combinatorial chemical reaction. Reaction parameters associated with individual reactor vessels are changed in response to the value measured during the reaction. Reaction parameters include temperature, pressure, stirring speed. The reaction occurring in one or more reactor vessels is quenched in response to values measured during the reaction. The measured values are used to calculate experimental results including temperature change, pressure change, percent conversion of starting material, and viscosity. The measured values and experimental results are displayed. In another aspect, the invention features a method for controlling a combinatorial chemical reactor.

    Abstract: A process for simultaneously testing a plurality of catalysts using combinatorial chemistry has been developed. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. Each bed of catalyst is then simultaneously contacted, at reaction conditions, with a reactant to form an effluent of each reactor. The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds. Each of the effluents is analyzed.
