  • Patent number: 10087306
    Abstract: This invention is based upon the discovery that the silica compounding additives of this invention can be included in silica reinforced rubber formulations to increase the low strain dynamic stiffness exhibited by the rubber composition without a substantial increase in the cured compound hysteresis. This increase in stiffness allows for use of process aids that would otherwise result in an unacceptable further reduction in low strain dynamic stiffness. The present invention specifically discloses a rubber formulation which is comprised of (1) a rubbery polymer, (2) a reinforcing silica, and (3) a silica compounding additive of the structural formula: wherein M represents a divalent metal, and wherein R1 and R2 can be the same or different and are selected from the group consisting of hydrogen atoms, alkyl groups, alkylene groups, hydroxyl substituted alkyl or alkylene groups, amine substituted alkyl or alkylene groups and thiol substituted alkyl or alkylene groups.

  • Patent number: 8409303
    Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

  • Patent number: 7772447
    Abstract: In a process for converting methane to liquid hydrocarbons, a feed containing methane is contacted with 0 dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons, including benzene and/or naphthalene, and produce a first effluent stream comprising hydrogen and 0t least 5 wt % m>35 aromatic hydrocarbons than said feed. At least part the aromatic hydrocarbons from the first effluent stream is then reacted with hydrogen to produce a second effluent stream having a reduced benzene and/or naphthalene content compared with said first effluent stream.

  • Publication number: 20100137665
    Abstract: A process is presented for the production of high value chemicals from lignin. The process comprises combining several internal steps to use the hydrogen generated by the process, rather than adding an external source of hydrogen. The process can combine the decomposition of oxygenates formed during the deoxygenation process with hydrogenation of deoxygenated lignin compounds.
