The wood biomass was liquefied by the pressurized hydrothermal method. The wood biomass powder in the different particle size, which was pulverized by a vibration mill, cutter mill and grinder, was used for the liquefaction. The liquefaction material was biomass slurry, which was prepared by mixing the wood biomass powder and water together (1:9). After filling the biomass slurry in a pressure ...

on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...

Widespread adoption of hydrogen as a vehicular fuel depends critically upon the ability to store hydrogen on-board at high volumetric and gravimetric densities, as well as on the ability to extract/insert it at sufficiently rapid rates. As current storage methods based on physical means--high-pressure gas or (cryogenic) liquefaction--are unlikely to satisfy targets for performance and cost, a g...

Liquefying hydrogen is an efficient way to store and transport hydrogen. However, the liquefaction process energy intensive. Therefore, integrated of natural gas utilizing mixed refrigerant cycle Claude proposed. The not only couples a steam methane reforming produce carbon dioxide refrigeration assist in pre-cooling, but also employs solar absorption system enhance efficiency. proposed simulat...

Hydrogen used as an energy carrier can provide important route to the decarbonization of supplies, but realizing this opportunity will require both significantly increased production and transportation capacity. One capacity is shipping liquid hydrogen, requires energy-intensive liquefaction step. Recent study work has shown that required in process be reduced through implementation new improve...

Third Graders’ Misconceptions about Evaporation and Liquefaction Phenomena A. Badriyaan, Ph.D. Concepts of evaporation and liquefaction are of significance in both daily life and the school curriculum, yet misconceptions about these two phenomena are frequent. To assess the extent of such misconceptions among third graders, a cluster sample of 132 of them from four schools i...

Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...

This paper presents prediction of liquefaction potential of soils by neuro-fuzzy models evaluated using Idriss and Boulanger method. In order to address the collective knowledge built up in conventional liquefaction method, an alternative Takagi-Sugeno-Kang reliant neuro-fuzzy model has been developed. Neuro-fuzzy is one of the artificial intelligence approaches that can be classified by machin...

Liquefaction is one of the most intriguing aspects of human tuberculosis. It is a major cause of the transition from the infection to active disease (tuberculosis, TB) as well as the transmission of M. tuberculosis to other persons. This paper reviews the natural history of liquefaction in humans from a pathological and radiological point of view and discusses how the experimental models availa...

To further clarify reasons for formation of condensed residues during the last stage of wood liquefaction in the medium of polyhydric alcohols and sulfuric acid catalyst, the weight loss behaviors and thermal reaction kinetics of condensed residues were studied by thermogravimetric analysis (TGA). Simultaneously, chemical methods were used to analyze the contents of lignin, cellulose, and holoc...
