Abstract

The present invention relates to methods for providing pyrolysis oil from holocellulose and lignin comprising biomass. The present methods provide, amongst others, an improved pyrolysis oil/char ratio or higher yield. The present methods additionally provide, amongst others, pyrolysis oils with improved carbon (C)/ oxygen (O) ratios or energy content. Specifically, the present invention relates to methods comprising the steps of separately introducing the biomass and a solid heat carrier with a temperature of 400°C to 700°C into a first reactor or first reaction zone; b) continuous mixing, in the absence of oxygen, of the biomass and solid heat carrier in the first reactor or the first reaction zone for providing a first time period of 0.5 to 5 seconds of pyrolytic processing yielding a mixture comprising partially pyrolyzed biomass and solid heat carrier and primary pyrolysis gas; c) introducing the mixture from the first reactor, or first reaction zone, into a second reactor, or second reaction zone, the second reactor, or second reaction zone, is configured to provide sedimentation, or separation, of solids at the bottom of the second reactor, or second reaction zone, by gravity thereby forming a layer of solids at the bottom of the second reactor, or second reaction zone; d) maintaining the mixture in the second reactor, or reaction zone, in the absence of oxygen, for a second time period of 10 to 1200 seconds of pyrolytic processing additionally yielding secondary pyrolysis gas and solid char, while collecting pyrolysis gasses from the second reactor, or reaction zone; condensing, preferably by quenching to temperatures of 60°C or less, the collected primary and secondary pyrolysis gasses into pyrolysis oil.

Abstract

The present invention relates to a method for controlling the water content in a pyrolysis liquid comprising: a) producing a pyrolysis vapour comprising condensable compounds and non-condensable gases at a temperature equal to, or below 70° C and at a pressure equal to or below 1.5 bar; b) introducing the vapour phase in a condenser, condensing the condensable compounds of the pyrolysis vapour to obtain a condensate at a temperature equal to, or below, 70° C and at a pressure equal to or below 1.5 bar, and separating the non-condensable gases from the condensate; c) introducing at least part of the condensate into concentrator and concentrating said condensate by removing a certain amount of water at a temperature equal 1 to, or below 80° C thereby obtaining a concentrate; d)introducing the concentrate obtained after step c) into condenser and mixing it with the condensate present in condenser thereby obtaining a pyrolysis liquid with controlled water content.

Abstract

A device for pyrolysing biomass comprises: a reactor space; a first feed for biomass material connecting to the upper zone thereof; a second feed for heated heat carrier material connecting to the upper side of the reactor space; a first discharge for pyrolysis gas connecting to the upper zone of the reactor space at a distance from the first feed; and a second discharge for solid material, for instance carbon and heat carrier material, connecting to the underside of the reactor space. A substantial separation between the discharge flows of pyrolysis gas and solid material takes place predominantly under the influence of gravitational force, without interposing of a cyclone. The reactor space is modeled such that the direct flow from the first feed and the second feed to the first discharge is blocked. A mechanical mixer is present in the reactor space for the purpose of mixing the flow of biomass material with the flow of preheated heat carrier material.
