  • Patent number: 10734814
    Abstract: A maintenance optimization control system for load sharing between includes a first engine having an associated first criteria, a second engine having an associated second criteria, and a load having a steady component and a transient component. The control system includes a controller communicably coupled to the first engine, the second engine and the load. The controller selects an engine from the first engine and the second engine based at least on the first criteria and the second criteria. The controller distributes the load between the first engine and the second engine such that only the selected engine is operated under transient component of the load.

  • Publication number: 20160016806
    Abstract: The invention refers to a process for producing activated carbon having catalytic activity by carbonization and subsequent activation of carbonaceous organic polymers, wherein carbonaceous organic polymers into which, in the course of their formation, at least one metal atom and/or metal ion has been interpolymerized are subjected to a carbonization and subsequent activation, forming an activated carbon loaded with the metal atom and/or metal ion. This obviates subsequent loading with the metal by costly and inconvenient impregnation after the activated carbon has been produced. By endowing the starting materials with the metal, moreover, a more homogeneous loading is achieved, and that homogeneous throughout all kinds of pores (i.e. macropores, mesopores and micropores), so that catalytic activity is enhanced, and in addition, activation is accelerated.

  • Patent number: 8927457
    Abstract: Disclosure is made of a specific process for producing activated carbon in spherical form, starting with organic polymer spherules based on styrene and divinylbenzene, wherein said polymer spherules contain chemical groups leading to the formation of free radicals and thus to cross-linkages by their thermal decomposition, in particular sulfonic acid groups. Furthermore, various application purposes for the thus-produced activated carbon spherules are named.

  • Patent number: 7785702
    Abstract: The present invention relates to a storage unit for gases, in particular a sorptive storage, with the storage unit comprising a sorbent for the reversible uptake of the gases to be stored and the sorbent being based on discrete sorptive particles. The sorptive particles are embedded in a solid gas-permeable three-dimensional support having a foam structure and/or are fixed thereto. The storage unit is particularly suitable for the storage of combustible or fossil gases, e.g. hydrogen, natural gas and the like, and thus as gas storage unit in power stations and motor vehicles.

  • Patent number: 7662747
    Abstract: The invention relates to a process for producing granular, particularly spherical activated carbon by carbonization of suitable carbonaceous polymers in the form of polymer granules, in particular polymer spherules, as a starting material, which are convertible by carbonization into carbon at least essentially, wherein the polymer granules, in particular the polymer spherules, are continuously moved through a carbonization apparatus comprising a plurality of temperature zones and/or a temperature gradient so that an at least essentially complete conversion of the starting material to carbon is effected.

  • Patent number: 7410693
    Abstract: Disclosed is an adsorbing material (1), particularly for producing protective suits, comprising an especially planar supporting material (2), an at least substantially air-impermeable, steam-permeable barrier layer (3), and an adsorbing layer (4). The baffler layer (3) is applied to the supporting material (2) and is used as an adhesive layer for the adsorbing layer (4) that is disposed on the face of the barrier layer (3), which lies opposite the supporting material (2). The baffler layer (3) is provided with a steam permeability of at least 20 l/m2 per 24 h at 25° C. and at a thickness of 50 ?m.
