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 carrier 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 1 is not exposed to the higher temperature T 2. As a result, secondary reactions of the bio-oil components are minimized.
