Investigation of organic desulfurization additives affecting the calcium sulfate crystals formation [PDF]
In the study, the optimal experimental conditions for gypsum crystals formation were 323 K, 300 rpm stirring speed. The major impurities of Mg2+, Al3+ and Fe3+ were found to inhibit calcium sulfate crystals formation. Fe3+ caused the strongest inhibition,

The Non-Iterative Transformation Method [PDF]
The Blasius flow is the idealized flow of a viscous fluid past an infinitesimally thick, semi-infinite flat plate. The definition of a non-iterative transformation method for the celebrated Blasius problem is due to T{\"o}pfer and dates more than a century ago. Here we define a non-iterative transformation method for Blasius equation with a moving wall,

The Value Chain of Sustainable Dual Carbon Sodium Ion Capacitors
Sodium‐ion capacitors (SICs) bridge the energy‐power gap between batteries and supercapacitors, offering sustainable and scalable energy storage solutions. This review provides a 360‐degree perspective on SIC technology, covering material choices, presodiation strategies, manufacturing challenges, applications and life cycle assessment to ensure ...

Carbonisation and Gasification
製鉄,都市ガス, 合成ガスの製造をは我国では別々に扱われることが多かつたが, 最近は技術的, 経済的に互に著しく接近してきた。将来は一括して化学工業のうちの一つの部門と考える方が妥当になる時がくるであろう。それらに共通する問題は特に日本の石炭事情に基いて粘結炭の代りに非乾留炭を原料とすることであるが, その技術の各国における現況をブリケット乾留, 微粉炭乾留, ガス化の項目別に述べた。

Survey of Biomass Gasification, Volume II: Principles of Gasification [PDF]
Biomass can be converted by gasification into a clean-burning gaseous fuel that can be used to retrofit existing gas/oil boilers, to power engines, to generate electricity, and as a base for synthesis of methanol, gasoline, ammonia, or methane. This survey describes biomass gasification, associated technologies, and issues in three volumes.

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...

Carbon‐negative hydrogen from ethanol via catalytic oxidative reforming
Abstract This study evaluated a commercial technology for producing low‐ or negative‐carbon hydrogen through ethanol catalytic oxidative reforming, focusing on the life cycle greenhouse gas emissions, or carbon intensity (CI). Various scenarios were analyzed: (a) comparing corn ethanol (first‐generation or Gen1 ethanol) and cellulosic ethanol (second ...
