Comminution and densification of biomass particles

Patent Number: 8465627
Publication Date: 2013-06-18
Inventors: ; ; ;

A method for reducing the mechanical strength of solid biomass material, in particular lignocellulosic biomass, comprises mixing the solid biomass material with an inorganic material and heating the solid biomass material mixture to a toasting temperature in the range of 105° C. to 140° C. during an exposure time of from 1 minute to 12 hours. Before or after the heat treatment, which is referred to as “toasting”, the biomass material mixture is subject to flash heating. The treatment ...

Publication Date: 2013-06-18
Inventors: ;

This invention relates to a coking oven in flat-type construction, a non-recovery or heat-recovery coking oven, which has at least one measuring apparatus for measuring the concentration of gaseous constituents of the coke oven retort, the coke oven hearth and/or the off gas duct, and in which, on the basis of these data, a process control computer determines and regulates the optimal supply of primary and/or secondary air. Also embraced by the invention is a coking method employing a ...

Biocoke producing apparatus and process therefor

Patent Number: 8460515
Publication Date: 2013-06-11
Inventors: ;

A biocoke producing apparatus has a reaction vessel that has a preset temperature range and pressure range for, without carbonizing of the pulverized biomass, inducing a pyrolytic or thermal curing reaction of lignin and hemicellulose thereof. The reaction vessel has a pressurization device for pressurizing to the pressure range, a heating device for heating to the temperature range in the state of the pressurization and a cooling device for cooling after maintaining of the above state. ...
