Offered by us is Calcined Petroleum Coke that is a carbonaceous solid derived from oil refinery coker units or other cracking processes. Relatively pure in carbon content, this type of coke is often used in industries as fuel. It can also be used for manufacturing dry cells, electrodes and other such products. Composition: - F.C. > 98 % - Ash 0.5%
As can be observed, pure Fe–Mn alyst performed the lowest conversion with the ratio of chlorobenzene conversion at about 90% when temperature reached as high as 400 °C. Upon addition of Ce to the Fe–Mn alyst, the ratio of chlorobenzene conversion remarkably increased up to a Ce content of 5%, and Ce(5%)–Fe–Mn was the most active among all alysts achieving ∼99% chlorobenzene
In our group 16,17, we prepared high-quality mesoporous titania thin films with good thermal stability (up to 600 °C) by using triblock copolymer Pluronic ® F127 as the structure-directing agent and tetrabutyl titanate as the inorganic precursor. The excellent thermal stability is correlated to the thick wall of the mesostrcture. The use of F127 as the templating agent was the premise for
their non-cultivability and availability as a pure microbial inoculant, as easy to use and apply as chemical fertilizers. In fact, if a nuer of commercial inoculants can be found worldwide, they represent, at the best, a very low taxonomic diversity
The permeances of pure nonaqueous solvents and separation performance of alcohol and alkane solutes in ethanol were investigated. Their modified silica–zirconia merane with an average pore size of 1 nm showed a MWCO of approximately 200 g mol –1 and permeate …

adding sodium hypochlorite (Wako Pure Chemical Industries, Osaka, Japan) to reverse osmosis (RO) water. The concentration of available chlorine was determined by the iodine titration method. The pH was adjusted to 6.0 with 1M HCl. A suspension of 0.05–0.4% calcinated calcium (DP-SC1, Taisho Technos, Tokyo) was prepared by adding it to water.

Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base.It has many industrial and niche appliions, most of which exploit its caustic nature and its reactivity toward acids.An estimated 700,000 to 800,000 tonnes were produced in 2005. KOH is noteworthy as the precursor to most soft and liquid soaps, as well as numerous potassium-containing chemicals.

A system for removing high purity salt from a brine. One system includes a first evaporator configured to receive a brine stream, to produce a first output comprising a sodium chloride slurry, and to produce a first intermediate output. The system also includes a second evaporator fluidly coupled to the first evaporator and configured to receive the first intermediate output, to produce a
An active, selective, and stable alyst (Ni in zeolite HZSM‐5) was developed to convert a wide variety of C O and C O bonds in n‐hexane‐extracted pyrolysis oil into hydrocarbons through a cascade of hydrogenation, hydrolysis, dehydration, and dehydroaromatization reactions. In their Communiion on page 5935 ff., J. Lercher and C. Zhao show that C 5 –C 9 gasoline‐range
Alumina (aluminium oxide) is a versatile oxide ceramic material. This blog post will look at the different commercial grades available.
Homochiral crystallizations of two enantiomeric metal−organic frameworks (MOFs) Ce−MDIP1 and Ce−MDIP2 were achieved by using l- or d-BCIP as chiral inductions, respectively, where the chiralities were characterized by solid state CD spectra. Ce−MDIPs exhibit excellent alytic activity and high enantioselectivity for the asymmetric cyanosilylation of aromatic aldehydes; the homochiral
There are many high-quality and even pure hydrogen varieties of activated carbon to search through. When browsing the selection you will see specific types that are shell or wood-based while others are coal-based. Certain activated carbon is sold loosely while other styles come in contained packing bags for neater utilization.
The objective of this research was to understand the dehydration mechanism of technical dihydrate and the variation of the physical properties of β -hemihydrate after the first hydration-dehydration process. In this study, the recycling mechanism of different hemihydrate types as raw material was investigated. The influence of the first hydration-dehydration process on the hydration rate
We optimized the control variables for zeolite synthesis and showed that phase-pure zeolite Na-A can be synthesized with CTA at reactant molar ratio, hydrothermal reaction temperature and reaction time of 1.3Na 2 O: 0.6Al 2 O 3: 1SiO 2: 38H 2 O at 80°C for 6 h, respectively, while phase-pure zeolite Na-X can be synthesized at 2.2Na 2 O: 0.2Al 2 O 3: 1SiO 2: 88H 2 O at 100°C for 8 h
