COMPARATIVE ANALYSIS OF DIFFERENT ACIDS UTILIZATION FOR CELLULOSIC HYDROLYSIS BY USING BRAZILIAN WOOD WASTES FOR FIBERS AND BIOETHANOL PRODUCTION YIELDS
- 1. Universidade Tecnológica Federal do Paraná
Description
This paper main objective is to determinate the hydrolysis efficiency by using four different diluted acids treatment: (H 2 SO 4 ) sulfuric, (HNO 3 ) nitric, phosphoric (H 3 PO 4 ) and acetic (CH 3 COOH), in attempt to improve the fibers and bioethanol production levels. In this study twelve Brazilian woods were investigated, including native and exotic species, hardwoods and softwoods. Processes to use wood waste recovery established to produce ethanol and cellulosic fibers simultaneously were carried out. For fermentation essay, a wild line of Saccharomyces cerevisiae yeast was investigated. The incomes related to hydrolysis efficiency, ethanol yields, fibrous fractions efficiency, and plus glucose and delignification levels using acid and alkaline treatments were tested. From the results it is possible to join the production of ethanol and cellulosic fibers simultaneously using wood chips, and due to the complexity of the analyzed material it´s still possible to isolate byproducts. Also from results, the yeast demonstrated to be efficient with an estimate maximum production of 12,94 liters per 100 kg of biomass using Balfourodendron riedelianum specimen and sulfuric acid hydrolysis. All acids and samples demonstrated high and similar efficiency in hydrolysis, indicating that these are feasible for hydrolysis processes use.

الهدف الرئيسي من هذه الورقة هو تحديد كفاءة التحلل المائي باستخدام أربعة أنواع مختلفة من معالجة الأحماض المخففة: (H 2 SO 4 ) الكبريتيك، (HNO 3 ) النيتريك، الفوسفوريك (H 3 PO 4 ) والخليك (CH 3 COOH)، في محاولة لتحسين مستويات إنتاج الألياف والإيثانول الحيوي. في هذه الدراسة، تم التحقيق في اثني عشر غابة برازيلية، بما في ذلك الأنواع المحلية والغريبة والأخشاب الصلبة والأخشاب اللينة. تم تنفيذ عمليات استخدام استعادة نفايات الخشب لإنتاج الإيثانول والألياف السليلوزية في وقت واحد. بالنسبة لمقال التخمير، تم التحقيق في خط بري من خميرة الخميرة الخميرية. تم اختبار الدخول المتعلقة بكفاءة التحلل المائي، وإنتاج الإيثانول، وكفاءة الكسور الليفية، بالإضافة إلى مستويات الجلوكوز والتحلل باستخدام العلاجات الحمضية والقلوية. من النتائج، من الممكن الانضمام إلى إنتاج الإيثانول والألياف السليلوزية في وقت واحد باستخدام رقائق الخشب، وبسبب تعقيد المادة التي تم تحليلها، لا يزال من الممكن عزل المنتجات الثانوية. أيضًا من النتائج، أثبتت الخميرة كفاءتها مع تقدير الحد الأقصى للإنتاج بـ 12.94 لترًا لكل 100 كجم من الكتلة الحيوية باستخدام عينة Balfourodendron riedelianum والتحلل المائي لحمض الكبريتيك. أظهرت جميع الأحماض والعينات كفاءة عالية ومتشابهة في التحلل المائي، مما يشير إلى أنها مجدية لاستخدام عمليات التحلل المائي.Translated Description (English)
