These results suggested that the product particles with HCl gas removal ability at high temperature can be prepared from PS using calcination and alkali reaction.Takaaki WajimaDepartment of Urban Environment Systems自然资源(英文)T. Wajima, Preparation of HCl gas sorbent from paper sludge, Nat. Resour...
All of the representative metals react directly with elemental halogens or with solutions of the hydrohalic acids (HF, HCl, HBr, and HI) to produce representative metal halides. Other laboratory preparations involve the addition of aqueous hydrohalic acids to co...
This molecular bond length of HCl (1.27 Å). Figure 3a–f provides the DOS for each supercell. For our simulation, we use the DFT + U approximation, with the U parameter equal to 8.2 eV for the Ti-3d orbital. For the undoped case, we calculate a band gap equal to 3...
Preparation of activated carbon The peanut shell used in this study was cleaned with an ultrasonic washer, and then dried in an oven at 110 ℃ for 12 h. The dried peanut shell was ground into powder, then immersed in a HCl (2 mol/L) solution to remove impurities, and finally oven...
A very similar X-ray pattern was obtained by washing LiTi 0.1Zr 1.9(PO 4) 3 with 0.3N HCl. Heating this phase, or NH 4Zr 2(PO 4) 3, above 600degC resulted in the appearance of a rhombohedral phase of HZr 2(PO 4) 3 with cell dimensions a=8.803(5) and c=23.23(1)Aring. The...
As shown in Scheme 1, a series of bio-In2O3 was prepared using an acid-etched pollen template, then the supported bio-In2O3-x/Pd catalysts (x denoted as the amount of HCl, mL) were fabricated using the impregnation-reduction method. Interestingly, we found that the CO2 conversion was...
The present invention relates to a process for the preparation of chlorine by gas phase oxidation using a supported catalyst based on ruthenium, characterised in that the catalyst s
HCl, HF, and underfluorinated halogenated hydrocarbon intermediates. The process is characterized by said chlorofluorination catalyst comprising at least one chromium-containing component selected from (i) a crystalline alpha-chromium oxide where at least 0.05 atom % of the chromium atoms in the alpha...
The reaction of an alcohol with a chlorosilane to form an organooxysilane is an equilibrium reaction exemplified by the following equation: =Si-Cl+ROH<->=SiOR+HCl Therefore, to drive the reaction to favor high yields of the organooxysilane it is desirable to remove the hydrogen chloride as ...
HCl gas slowly evolves. The dark orange emulsion is stirred for c. 30 h at room temperature and then poured into water and extracted with toluene. The organic phase is isolated and concentrated on a rotary evaporator. The resultant oil is fractionated under vacuum to give, at 88°-92° C...
