摘要: The aim of the present work was to find an optimum kraft pulping process for olive tree pruning (OTP) in order produce a bleachable grade pulp Kappa number about 17. produced under optimized conditions showed viscosity 31.5 mPa.s and good physical, mechanical, optical properties, which are acceptable paper production. strength properties were measured on pulps unrefined refined PFI mill with up 2000 revolutions before after bleaching. OTP bleached 90% ISO brightness (kappa < 1); however demanded long sequence stages, OD(EP)D(EP)D, higher than usual total chemical dosage (24.78 kg/odt pulp). Overall, is suggested as interesting raw material cellulosic production because its comparable those other agricultural residues currently used industry.
