This research aimed to observe the effects of the action of cellulase enzymes during cellulose refining for paper production in a context in which the cost of electricity has been a challenge for the industries. This paper deals with general concepts about paper production as well as the mechanism of functioning of the enzymes as well as the specific action of the cellulase enzyme on the cellulose substrate. The enzymatic compounds used were supplied by two different companies. The total of compounds tested was three, being applied in two different substrates. The tests were carried out in a triplicate laboratory refiner and the efficiency of the process was evaluated by the degree of refining of the mass up to 35 ºR in relation to the time. From this refined mass were formed sheets of paper weighing approximately 100 g / m2 and from these sheets tests were performed to verify the effects of the enzymatic refining on the physical-mechanical properties of the sheets of papers. As a result, the reduction of energy consumption by 57% was observed with the use of the enzymatic compound Y1, which made it possible to save R$34,55 per ton of pulp. When projecting this amount for a monthly expense of 1512 tons, estimated for an industrial refiner of capacity 50,4 tons / day, the economy is around R$37561,17. The results indicate the feasibility of the use of enzymatic compounds in the cellulose refining, so that the investment related to the use of enzymatic compounds can help solve the energy expenditure in the paper industry. |
