Jan 01, 2020· Development of renewable energy is essential to mitigating the fossil fuel shortage and climate change issues. Here, we propose to produce a new type of energy, bio-coal, via a fast pyrolysis coupled with atmospheric distillation process. The high heating values of the as-prepared bio-coals from the representative biomass are within 25.4 to 28.2 MJ kg−1, which are comparable to that of the ...

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Ammonia production has become one of the most important industries in the world. Without the crop yield made possible by ammonia-based fertilizers and chemicals, the global population would be at least two to three billion less than it is today (3).Ammonia production has increased steadily since 1946 (), and it is estimated that the annual production of ammonia is worth more than $100 billion ...
Synthetic methods should be designed to maximize incorporation of all materials used in the process into the final product.. Contributed by Michael Cann, Ph.D., Professor of Chemistry, University of Scranton. The second principle of green chemistry can be simply stated as the "atom economy" of a reaction.
A British physician, Gesner developed a process to extract the inflammable liquid from asphalt, a waxy petroleum mixture. The term kerosene is, in fact, derived from the Greek word for wax. Sometimes spelled kerosine or kerosiene, it is also called coal oil because of its asphalt origins.
By contrast, a drug manufacturer can change the manufacturing process extensively and analyze the finished product to establish that it is the same as before the manufacturing change. The living systems used to produce biologics can be sensitive to very minor changes in the manufacturing process.
A method for producing a bio-coal includes the following steps: (a) lowering the moisture content of a fiber residue obtained after oil extraction of oil palm fruit to less than 25%; (b) after step (a), cutting the fiber residue; (c) after step (b), pelletizing the fiber residue into short-fiber pellets; (d) drying the short-fiber pellets to reduce the moisture content of the short-fiber ...
The processes for production of specific chemicals from coal are typically proprietary systems using specialized process systems. In the following discussion, some of the processes for important chemicals such as formaldehyde, olefins, etc. are presented. Methanol (MeOH) is of course another important primary chemical made from coal syngas; however, it is also a liquid fuel in its own right ...
The boundaries of the chemical industry, then, are somewhat confused. Its main raw materials are the fossil fuels (coal, natural gas, and petroleum), air, water, salt, limestone, sulfur or an equivalent, and some specialized raw materials for special products, such as phosphates and the mineral fluorspar.The chemical industry converts these raw materials into primary, secondary, and tertiary ...
Chemistry. The Fischer-Tropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the ...
Process Manufacturing takes a formulation or recipe of ingredients and blends them together using a chemical reaction, heat, cold, fermentation, etc continuously or in a batch into a final product which is usually a liquid, powder, gas or solid. (Think turning milk into baby formula, oil refining, gasoline, general anesthetic, plastic, cheese, butter, paint or pharmaceutical manufacturing,)
Bio Coal Manufacturing Process. Bio coal manufacturing process biochar making machinetar and wood vinegar are chemical materials which can be sold to the chemical production industry directly during the biochar production process combustible gas will be used as fuel replacing coal wood and natural gas of traditional gas which has largely reduced the consumption of

Douglas C. Elliott, in Encyclopedia of Energy, 2004 3.4 Potential Gasification Products. Whereas the pyrolysis process results in a product that retains much of the chemical functional character of the biomass feedstock, gasification operates under more severe process conditions and results in products of a relatively simple chemical structure but with wide applications.
