    Lignocellulosic material is an abundant renewable resource with the potential to replace petroleum as a feedstock for the production of fuels and chemicals. The large scale deployment of biomass saccharification is, however, hampered by the necessity to use .   Industrial production of a wide range of value‐added products heavily relies on fossil resources. Lignocellulosic biomass materials are receiving increased attention as a renewable, economical, and abundant alternative to fossil resources for the production of various value‐added products. Biomass feedstocks utilized for these productions include energy crops, agricultural biomass .

      The use of non‐food sources, such as corn stover, wheat straw, woody biomass or organic matter from municipal solid waste (MSW), for ethanol production is known as ‘Second‐generation’ (2G) bioethanol. 2G ethanol has been considered to be a promising alternative to 1G ethanol. Energy crops are low-cost and low-maintenance crops grown solely for energy production by combustion (not for food). The crops are processed into solid, liquid or gaseous fuels, such as pellets, bioethanol or fuels are burned to generate electrical power or heat. The plants are generally categorized as woody or plants include willow and poplar, herbaceous plants.

    In view of high-energy consumption, high baking cost, and serious pollution emission during the baking process of tobacco leaves, thermogravimetric analysis is employed to investi.

Corn straw and biomass blends by Zhengqi Li Download PDF EPUB FB2

Corn is one of China's three major crops and its straw is rich in resources. Understanding the mechanism of corn straw combustion in a fixed bed will help the clean and efficient use of corn straw as a source of energy. This book covers the issues of corn production and related discussion.

Cotton stalk and corn straw can be fully mixed. Dynamics calculation results show that: corn straw/cotton stalk blends pyrolysis behaviors can be well described by two-dimensional diffusion model.

And blend shows the lowest activation energy. The value of activation energy decrease with increasing corn straw content in the blend. by: 5. The sintering temperatures reduced with biomass addition ratio increasing. Fang and Jia studied the ash fusion temperatures of coal and straw blends, four typical temperatures of ash fusion were measured, the ash fusion temperature curves showed a trend of decreasing to increasing with ratio of corn straw addition increasing.

All the four Cited by: 8. Compared with SS, agricultural biomass such as corn straw (CS) can produce higher quality fuels through pyrolysis/gasification (Manara and Zabaniotou, ), but its production varies largely with the seasons and geographical location resulting in the instability of fuel supply.

Therefore, co-treatment of SS and CS seems a satisfactory solution. The chemical-looping gasification kinetics of corn straw with iron-based oxygen carrier to produce syngas were studied using thermogravimetric analysis.

The main reactions of corn straw based on iron-based composite oxygen carrier is divided into three stages: the pyrolysis stage (– °C), the gas-solid reaction stage (– °C.

The types of biofuel were selected via investigation of typical Chinese biofuel usage. Straw of rice, wheat, corn, beans, oil-bearing crops and cotton were the major contributors to the total crop residue production, accounting for %, %, %, %, % and %, respectively (Zeng et al., ).In some regions short of straw, wooden logs were combusted as supplementary fuels.

Feedstock blending strategy. A promising strategy to reduce supply risk is to blend different biomass feedstocks. Blending has been used by many industries (e.g., coal and animal feed) to affect the quality of the feedstock [].In the coal industry, different grades of coal are blended in order to meet emission targets and minimize ash production during power generation [25–27].

Lignocellulosic biomass is a vital resource for providing clean future energy with a sustainable environment. Besides lignocellulosic residues, nonlignocellulosic residues such as sewage sludge from industrial and municipal wastes are gained much attention due to its large quantities and ability to produce cheap and clean energy to potentially replace fossil fuels.

These cheap and abundantly. During the combustion of solid fuels, the undesired effects of ash transformation include bed agglomeration, slagging, and fouling processes. In particular, a problematic consequence of bed agglomeration is the defluidization process, resulting from the disappearance of gaseous bubbles that are created behind air distributors.

A parametric study of the gasification of four feedstocks (corn stover, switchgrass, wheat straw, and wood) has been performed on an experimental, pilot-scale ( ton/day) gasification facility. A comparison was made of the performance of the gasifier as a function of feedstock, in terms of the syngas production and composition.

In these experiments, pelletized feedstock was used, so that the. With the development of biomass power generation technology, the use of agricultural straw balers fits the needs of my country's economic development at that time.

As we know, our country is the most populous country in the world, but its primary power reserves are small, during which coal reserves are 1/10 of the world's, oil reserves are 1/ In the present study, the pyrolysis of corn (maize) straw pellets was performed under different temperatures (, and °C) at a 10°C min −1 heating rate and 30 min residence time, and the characteristics of biochar pellets were carefully investigated, particularly their elemental composition, hydrophobicity and mechanical.

Biomass-derived photothermal conversion materials are considered to be promising evaporator choices for cost-effective, sustainable, and environmentally friendly solar vapor generation. Herein we demonstrate a double-layer flamed straw, which is a typical solar-driven interfacial evaporator that can directly convert solar energy into heat and then localize heat at interface for vapor.

Biomass samples of ginkgo leaves (GK), pine needles (PN), corn straw (CS), aspen leaves (AS), and white poplar leaves (WP) were collected in autumn from urban areas of Anshan city, which is located in the northeastern part of China.

The original morphology of selected biomass samples are shown in Fig. The biomass energy source has been a promising renewable alternative for fossil fuels and their inevitable environmental impacts on Earth’s life, from which the greenhouse gas (GHG) emissions and the environment pollution followed by consequent ecosystem imbalance are major concerns.

Biofuels and bioplastics are well-known examples of renewable products obtained from biomass. This is because partial evolution of these gases takes place during the torrefaction process; hence, the resulting torrefied biomass has a lower chlorine mass fraction than its raw biomass precursor.

Research showed that, during torrefaction of corn straw, the predominant chlorinated species in the evolving gas (“torgas”) are CH3Cl and HCl.

biomass (LCB) as feedstock for ethanol production (O’Brien et al.). Corn is an annual crop. The production of corn grain is machinery intensive. Fossil fuels are used to fuel diesel powered tractors and to produce nitrogen fertilizers.

The production of ethanol from corn. The release of chlorine (Cl) and sulfur (S) during biomass torrefaction and pyrolysis has been investigated via experiments in two laboratory-scale reactors: a rotating reactor and a fixed bed reactor. Six biomasses with different chemical compositions covering a wide range of ash content and ash-forming elements were torrefied/pyrolyzed in the temperature range of – °C.

There are more factors that can affect the combustion of blended fuels than the single fuel. Among these factors the ration of the fuels component is the most important one. In this paper, Pyris 1TGA thermobalance analyzer was used to research the combustion characteristics of coal (Qitaihe-coal) and biomass (corn straw) and their blends.
