Influence of Bio-Coal Properties on Carbonization and Bio-Coke Reactivity

چکیده
Coke corresponds to 2/3–3/4 of the reducing agents in BF, and by partial replacement coking coals with 5–10% bio-coal, fossil CO2 emissions from BF can be lowered ~4–8%. Coking coal blends 5% 10% additions bio-coals (pre-treated biomass) different origins pre-treatment degrees were carbonized at laboratory scale a bio-coal addition technical scale, aiming understand impact on properties (ash amount composition, volatile matter content) bio-coke reactivity. A thermogravimetric analyzer (TGA) connected quadrupole mass spectroscope monitored residual off-gases during carbonization. To explore effect plasticity, optical dilatometer tests conducted for addition. The plasticity was increasing addition, but pyrolyzed biomass had less negative compared torrefied biomasses high content oxygen. temperature starting gasification coke general greater extent bio-cokes produced containing higher contents catalyzing oxides. There no significant difference coke, terms reactivity as measured TGA. Bio-coke pelletized showed similar strength reference after reaction.

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Influence of geometry on mechanical properties of bio-inspired silica-based hierarchical materials.
Diatoms, bone, nacre and deep-sea sponges are mineralized natural structures found abundantly in nature. They exhibit mechanical properties on par with advanced engineering materials, yet their fundamental building blocks are brittle and weak. An intriguing characteristic of these structures is their heterogeneous distribution of mechanical properties. Specifically, diatoms exhibit nanoscale po...
متن کاملSome Properties of Ciliate Bio-operations
The process of gene unscrambling in ciliates (a type of unicellular protozoa), which accomplishes the difficult task of re-arranging gene segments in the correct order and deleting non-coding sequences from an “encrypted” version of a DNA strand, has been modeled and studied so far from the point of view of the computational power of the DNA bio-operations involved. Here we concentrate on a dif...
