发明名称 PROCESS OF INCREASING THE YIELD OF PULP BY OXYGEN PRETREAT- METN OF WOOD CHIPS PRIOR TO CHEMICAL PULPING
摘要 Process for breaking down wood chips, by chemical means, is claimed, where there is a water content in the wood material. Before the chemical decomposition process, the wood chips are placed in a pressure reactor to be treated by heat and oxygen so that the wood chips retain their water content. Pre-treatment phase ensures that the wood yielding process is accelerated to gain more slurry from the wood supply.
