However, they have limitations, notably the energy provided per unit volume of pellets, which, while greater than that of biomass in the form of sticks or white pellets, is still 30% to 40% less than that of carbon for the same volume or weight. %

Embodiment Construction

[0036] The invention will be better understood by reading the following detailed description of non-limiting embodiments of the invention with reference to the accompanying drawings in which:

[0037] - figure 1 is a schematic diagram of the present invention.

[0038] Rationale of the invention

[0039] figure 1 is a flow diagram of an apparatus for practicing the invention.

[0040] It implements a method for producing sheets or briquettes (also called "black pellets") from lignin-containing biomass comprising the following steps:

[0041] (a) Pretreatment of biomass (1) in a plant (10) for reduction of particles of a few cubic centimeters and optionally partial drying to achieve dust, sawdust, wood shavings , chips, cellulose shavings, flakes, trimmings or chips.

[0042] (b) The thus pretreated biomass is passed into the reactor (20) in order to heat the biomass particles to a temperature of 180 to 235°C by injecting steam (21) into the reactor (20). The first feed...

Abstract

The invention relates to a method for producing biomass, comprising a steam cracking step for producing granular combustible products, characterized in that said method comprises a step of mixing, prior to said granulation step, an intermediate powdered product resulting from the steam cracking of biomass with a powdered material having a high lignin content.

Description

[0001] The present invention relates to the field of development of lignocellulosic biomass, in particular for the production of fuels of the "black pellet" type with a high calorific value. technical field [0002] Conversion of lignocellulosic biomass (wood, agricultural waste, co-products of agriculture and agro-industry) into energy-dense, transportable and easily storable compounds will make it possible to develop and consolidate a stationary energy-industrial sector ( Biofuels used at fixed points in households) and with reduced environmental impact (CO 2 Fossil emissions, use of biomass without fertilizers or phytosanities). [0003] The black pellets are moisture-degradable cylinders, 1 to 3 cm long, and have good mechanical resistance, allowing storage and handling similar to carbon. It burns with little ash and has a low calorific value (LCV) of approximately 18 to 20 joules per gram of dry material. [0004] Black pellets are produced from lignocellulosic biomass ...
