Abstract

a presente invenção se refere a um método para pré-tratamento de um material de partida de madeira macia que compreende as seguintes etapas: a) pré-tratamento do material de partida de madeira macia em um processo de pré-tratamento para formar uma pasta; b) medição da concentração de glicose e da concentração de manose na pasta formada na etapa a); c) cálculo de proporção de glicose: manose das concentrações medidas na etapa b) d) comparação da proporção calculada na etapa c) com um valor de referência e se a proporção calculada na etapa c) difere do valor de referência, controlando pelo menos um parâmetro de processo do método de pré-tratamento em resposta à diferença.
