Continuous coal processing method [PDF]

open access: yes, 1980
A coal pump is provided in which solid coal is heated in the barrel of an extruder under pressure to a temperature at which the coal assumes plastic properties.

Root tip excision‐induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon

open access: yesNew Phytologist, EarlyView.
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

Plane flame furnace combustion tests on JPL desulfurized coal [PDF]

open access: yes
The combustion characteristics of three raw bituminous (PSOC-282 and 276) and subbituminous (PSOC-230) coals, the raw coals partially desulfurized (ca -60%) by JPL chlorinolysis, and the chlorinated coals more completely desulfurized (ca -75%) by JPL ...

UV-light-driven prebiotic synthesis of iron–sulfur clusters [PDF]

open access: yes, 2017
Iron–sulfur clusters are ancient cofactors that play a fundamental role in metabolism and may have impacted the prebiotic chemistry that led to life.

Molybdenum Dioxide in Carbon Nanoreactors as a Catalytic Nanosponge for the Efficient Desulfurization of Liquid Fuels

open access: yesAdvanced Functional Materials, 2019
The principle of a “catalytic nanosponge” that combines the catalysis of organosulfur oxidation and sequestration of the products from reaction mixtures is demonstrated.

Turning Microstructure in Block Copolymer Membranes: A Facile Strategy to Improve CO2 Separation Performance

open access: yesAdvanced Science
To mitigate global climate change, the development of membranes with high CO2 permeability and selectivity is urgently needed. Here, a simple and effective non‐solvent‐induced microstructure rearrangement (MSR) technique is proposed to enhance the gas ...

Exploring the Mechanism of Biocatalyst Inhibition in Microbial Desulfurization [PDF]

open access: yes, 2013
Microbial desulfurization, or biodesulfurization (BDS), of fuels is a promising technology because it can desulfurize compounds that are recalcitrant to the current standard technology in the oil industry. One of the obstacles to the commercialization of

Increasing the Selectivity for Sulfur Formation in Biological Gas Desulfurization

open access: yesEnvironmental Science and Technology, 2019
In the biotechnological desulfurization process under haloalkaline conditions, dihydrogen sulfide (H2S) is removed from sour gas and oxidized to elemental sulfur (S8) by sulfide-oxidizing bacteria.

Study of desulfurization with magnesite desulfurizer under hot metal pretreatment

open access: yesMetalurgija, 2018
In this paper, MgO 38 %, C 10 %, Al 12 %, Fe2O3 34 %, SiO2 + CaO 5,3 %, CaF2 0,7 % as the new desulfurizer ratio composition. Adding FeS, heating in a high temperature furnace, and then studying the reaction product composition by phase analysis.
