The present invention relates to a reaction method and apparatus, suitable for producing fuel by reaction of bio-oil with oil and/or melt. The present inventors have found that where bio-oil vapour is flowed into a reaction chamber and heated together with oil/melt (e.g. hydrocarbon oil/melt), a product useful as a fuel (e.g. as a diesel fuel) can be produced. This provides a particularly convenient method for cracking oil/melt. Advantageously, by providing the bio-oil as a vapour, the formation and accumulation of char in the reaction chamber can be reduced or avoided. The bio-oil vapour and the oil and/or melt may be heated together without the addition of a catalyst.
