Abstract:
A method for purifying a combustible gas that is contaminated with contaminants, such as tar and/or dust particles, comprises feeding oil to the contaminated gas. The oil evaporates through contact with the contaminated gas. Said evaporated oil is condensed on a quantity of the contaminants in such a manner that said contaminants grow in size to form particles of increased size in the gas. An electric field between electrodes is applied, by means of which said particles of increased size are electrically charged and removed from the gas. The condensation of the oil takes place at a temperature above the water dew point of the contaminated gas. This water dew point is preferably between 50-100 °C, in particular between 50-80 °C.
Abstract:
The invention relates to a process for the production of synthesis gas comprising (a) providing a gaseous hydrocarbon stream (15) ; (b) subjecting a first part of the gaseous hydrocarbon stream to an endothermic reaction thereby producing a first gaseous reaction product containing hydrogen (17) ; (c) subjecting a second part of the gaseous hydrocarbon stream(25)to an exothermic reaction thereby producing a second gaseous reaction product containing hydrogen (27) ; (d) transferring thermal energy from said exothermic reaction to said endothermic reaction; and (e) combining the first gaseous reaction product and the second gaseous reaction product produced in steps (b) and (c) , thereby forming a gaseous reaction products mixture (37) and to a reactor (l)that can be used for such a process.
Abstract:
Method and system for the production of solids from raw materials. These materials are subjected to a continuous torrefaction treatment at a temperature of between 200 and 320°C. Heating takes place by means of circulating gases that entor into direct heat exchange with the raw materials fed to the torrefaction chamber. The ga.es liberated during torrefaction are combusted while feeding in oxygen and discharged after the beat has been extracted from the flue gas thus produced. The heat from the flue gas is used to heat the gaseous medium that is fed to the torrefaction chamber. The production of effluent is prevented in that the condensate formed in the process is combusteal, optionally after specific purification steps.

Abstract:
A blade of a wind turbine is presented. This blade is provided with a root section for connecting the blade to the shaft or hub of the turbine. The blade also contains a wind-energy-absorbing profile which is optimized for wind flow. The output of the wind turbine is increased by providing the root section with a member that is designed in such a way that the assembly consisting of said member and the root section can absorb wind energy and will increase the overall efficiency of the wind turbine.
Abstract:
A photo-voltaic cell has a first and second two-dimensional array of contact points on the first surface, each coupled to a respective one of base and emitter areas in or on the semi-conductor body. Electrically separate first and second conductor structures on the first surface emanate from each contact point, coupled to contact points of the first and second two-dimensional array respectively. The first conductor structure comprises sets of first conductor line branches, the first conductor line branches of each set branching out from a respective one of the contact points of the first two-dimensional array in at least three successive different directions at less than a hundred and eighty degrees to each other. The second conductor structure comprise second conductor line branches in at least three different directions in areas between respective pairs of adjacent non-parallel ones of the first conductor line branches, each second conductor line branch coupled at least to a respective one of the contact points of the second two-dimensional array.
Abstract:
A method for torrefaction of biomass using a torrefaction reactor vessel having stacked trays including: feeding the biomass to an upper inlet of the vessel such that the biomass material is deposited on an upper tray of a vertical stack of trays in the reactor; cascading the biomass down through the trays by passing the biomass through an opening in each of the trays to deposit the biomass on a lower tray; as the biomass moves around each of the stacked trays, heating the biomass material with an oxygen deprived gas; extracting moisture containing gas having passed through the biomass on the upper trays wherein the extraction is immediately below each of the upper trays; as the biomass undergoes torrefaction in the lower trays of the stacked trays, retaining the gas with the biomass until the biomass falls from the stacked trays to a pile of biomass in the reactor vessel; exhausting gases containing organic compounds volatized by the torrefaction of the biomass through a gas outlet on the vessel at an elevation between the stacked trays and the pile of biomass, and discharging torrefied biomass from a lower outlet of the torrefaction reactor vessel.
Abstract:
The invention relates to the addition of active charcoal and steel slag to contaminated materials such as, for example, industrial residues, dredged material, residues from the clean-up of soil and contaminated soil which in terms of leaching are critical for heavy metals and/or organic microcontaminants. Active charcoal and steel slag can be added to these materials as an additive (for example in situ) in order to reduce leaching and the risk of spreading of contaminants. Surprisingly it is found that as a result of the use of the invention the contaminants in, for example, contaminated soil or bottom ash, etc. are immobilised.
