发明名称 PROCESS OF INCREASING THE YIELD OF PULP BY OXYGEN PRETREATMENT 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.
