Counter-current process for biomass conversion

TLDR
In this paper, a countercurrent process for converting solid biomass material is described, where the solid biomass is subjected to a first conversion at a first temperature T 1 and a second conversion at the second temperature T 2 such that T 2 > T 1.
Abstract
A countercurrent process is disclosed for converting solid biomass material. The solid biomass material travels through a reactor system in countercurrent with hot heat carrier materials, such as particulate heat earner material and hot gases. The solid biomass material is subjected to a first conversion at a first temperature T 1. and a second conversion at a second temperature, T 2, such that T 2 > T 1. Bio-oil produced to at T J is not exposed to the higher temperature T 2. As a result, secondary reactions of the bio-oii components are minimized.
