Abstract:
Cubic diamond was synthesized with two systems, (1) graphite with pure magnesium carbonate (magnesite) and (2) graphite with mixed potassium and magnesium carbonate at pressures and temperatures above 9.5 GPa, 1600 °C and 9 GPa, 1650 °C, respectively. At these conditions (1) the pure magnesite is solid, whereas (2) the mixed carbonate exists as a melt. In this pressure range, graphite seems to be partially transformed into hexagonal diamond. Measured carbon isotope δ13C values for all the materials suggest that the origin of the carbon source to form cubic diamond was the initial graphite powd

Калий является одним из наиболее важных элементов в организме. Он должен поступать в организм ежедневно с кормами, поскольку сохраняется в нём короткое время и является донором катионов. Избыток всосавшегося калия выводится, в основном, через мочу. Он входит в состав буферных систем, поддерживает нормальное осмотическое давление, способствует процессам пищеварения, участвует в процессах синтеза белков и гликогена, тормозит сердечные сокращения. Калий поддерживает солевой баланс организма, состояние которого влияет на синтез белка, рост мышц и укрепление нейронных связей, на энергетическую сист

In the extraction systems of hexane–aqueous solutions of potassium carbonate, ammonium sulfate and sodium chloride, the distribution of a number of organic compounds (benzyl alcohol, tetrahydrofuran, phenol, aniline, pyridine, pyridazine, pyrimidine, n-butylamine, diethylamine, triethylamine, benzylamine) was studied. It was shown that sodium chloride, the most frequently used as a salting out agent, is noticeably inferior in salting ability to potassium carbonate, dipotassium phosphate and ammonium sulfate, since it contains singly charged ions with a relatively low charge density.

The transesterification reaction of sucrose and fatty acid methyl esters to produce sucroesters was experimentally evaluated using commercial emulsifiers as compatibility agents. Reactions were carried out at temperatures between 100 and 140°C, using emulsifier concentrations in the range of 5 to 15 %wt, and potassium carbonate as catalyst. Fatty acid methyl esters consumption and sucroesters production was monitored by HPLC analysis of samples. Methyl esters conversions around 40 % were obtained with 68 %wt monoester content in sucroesters mixture. Despite the reaction times were reduced by o

Att begränsa globala uppvärmningen till 1,5°C kommer kräva negativa koldioxidutsläpp. En metod för att generera negativa koldioxidutsläpp är så kallad Bio-Energy Carbon Capture and Storage (BECCS). En direkt implementering av BECCS är att fånga in CO2 från rökgas som genereras vid förbränning av biomassa i en så kallad post-combustion capture-konfigurering. Post-combustion BECCS har skapat en stor resonans hos kraftverksoperatörer och pappersproducenter.

Abstract:
The goal of the present manuscript is the investigation of two novel systems for partial CO2 capture from the exhausts of fossil fuelled powerplants. These systems should be relatively cheap and easily applicable to existing powerplants with minor modification, in order to make them accessible by a large range of users and favour a significant diffusion of partial CO2 sequestration. Two basic processes were proposed: 1. Absorption with a liquid solution of water and NH3; 2. Absorber/desorber system with a liquid solution of water and phosphates.

Abstract Rock heterogeneities, such as variations in pore distribution, pore throat diameter, and initial permeability, significantly affect the outcome of carbonate matrix stimulation treatments. A better understanding of the influence of these parameters on stimulation and diversion, especially for the performance of self-diverting acids, is needed for efficient stimulation designs. Carbonate rock samples from six outcrop formations, with permeability ranging from 2 to 150 md, were used in the study.

The National Energy Technology Laboratory (NETL) as well as Li et al. [1] have shown that integrating a catalytic coal gasifier with a solid oxide fuel cell (SOFC) can achieve high system efficiencies (∼60%) while capturing and sequestering >90% of the carbon dioxide. Integration of a catalytic gasifier with a SOFC is aided by the minimal exergy destruction inside a catalytic, steam-coal gasifier producing a high-methane content syngas, and the decreased exergy destruction in the SOFC due to the ability to operate at lower air stoichiometric flow ratios compared with a SOFC operating only o
