Carbonate process

This reaction is an undesirable side reaction in the manufacture of hydrogen but utilised as a means of removing traces of carbon monoxide left at the end of the second stage reaction. The gases are passed over a nickel catalyst at 450 K when traces of carbon monoxide form methane. (Methane does not poison the catalyst in the Haber process -carbon monoxide Joes.)... [Pg.181]

Sodium bicarbonate may be prepared by the ammonia-salt (Solvay) process. Carbon dioxide is passed through a solution of sodium chloride in ammonia water. Sodium bicarbonate is precipitated and the ammonium chloride remains in solution. The ammonium chloride is heated with lime to regenerate ammonia (see Alkali AND CHLORINE PRODUCTS). [Pg.200]

A.lkanolamine Process. Carbon dioxide is an acidic gas that reacts reversibly with aqueous alkaline solution to form a carbonate adduct. This adduct decomposes upon the addition of low level heat faciUtating CO2 removal. An aqueous solution of 15—20 wt % monoethanolamine (MEA) was the standard method for removing CO2 in early ammonia plants. [Pg.349]

At room temperature, Htde reaction occurs between carbon dioxide and sodium, but burning sodium reacts vigorously. Under controUed conditions, sodium formate or oxalate may be obtained (8,16). On impact, sodium is reported to react explosively with soHd carbon dioxide. In addition to the carbide-forrning reaction, carbon monoxide reacts with sodium at 250—340°C to yield sodium carbonyl, (NaCO) (39,40). Above 1100°C, the temperature of the DeviHe process, carbon monoxide and sodium do not react. Sodium reacts with nitrous oxide to form sodium oxide and bums in nitric oxide to form a mixture of nitrite and hyponitrite. At low temperature, Hquid nitrogen pentoxide reacts with sodium to produce nitrogen dioxide and sodium nitrate. [Pg.163]

Recovery of hydrogen cyanide from coke-oven gases has been dormant in the early 1990s, but new methods involving environmental control of off-gas pollutants may be lea ding the way for a modest return to the recovery of cyanide from coke-oven gases (see Coal conversion process, carbonization). [Pg.379]

As in the fixed bed process, carbon is deposited on the surface of the catalyst and covers the active sites. This deposit lowers the activity very rapidly. [Pg.19]

Various design and operating problems have been experienced by most developers of methanation systems. Specifically, carbon formation and catalyst sintering are two of the more common problems in methanation processes. Carbon formation refers to the potential production of carbon from carbon oxides and methane by the following reactions. [Pg.150]

In the Fischer-Tropsch process, carbon monoxide reacts with hydrogen in the presence of a solid catalyst, with the formation of a mixture of hydrocarbons. The composition of the product varies considerably with the catalyst and the operating conditions. The mixture may include (in addition to hydrocarbons) alcohols, aldehydes, ketones, and acids. [Pg.76]

Direct conversion of methane to ethane and ethylene (C2 hydrocarbons) has a large implication towards the utilization of natural gas in the gas-based petrochemical and liquid fuels industries [ 1 ]. CO2 OCM process provides an alternative route to produce useful chemicals and materials where the process utilizes CO2 as the feedstock in an environmentally-benefiting chemical process. Carbon dioxide rather than oxygen seems to be an alternative oxidant as methyl radicals are induced in the presence of oxygen. Basicity, reducibility, and ability of catalyst to form oxygen vacancies are some of the physico-chemical criteria that are essential in designing a suitable catalyst for the CO2 OCM process [2]. The synergism between catalyst reducibility and basicity was reported to play an important role in the activation of the carbon dioxide and methane reaction [2]. [Pg.213]

SE-BR has several outstanding properties. Above all it has improved processability. Carbon black-filled compounds based on commercial BR show the well known bagging and sagging effects on the batch-off mill (13) unless the BR is blended with NR or SBR. Figure 5 shows a compound based entirely on Ti-BR and containing 50 parts of carbon black, at various times on the roll mill. [Pg.62]

There are three main species in the process carbon, hydrogen, and oxygen. We thus can write a balance for each species as follows ... [Pg.322]

For more recent dating processes carbon dating is used. With a half-life of 5717 years 14C dating relies on the replenishment of the 14C parent species, which occurs by neutron capture. The process occurs in the atmosphere as a result of bombardment of the Earth with neutrons ... [Pg.168]

Phthalic anhydride and urea, together with copper(I)chloride and ammonium molybdate, are heated to 200°C in trichlorobenzene. The ratios between the components are the same as in the baking process. Carbon dioxide and ammonia are released to yield Copper Phthalocyanine Blue. The reaction is complete after 2 to 3 hours, producing a yield between 85% and more than 95%. [Pg.430]

The quantatitive determination of the elements in an organic substance is known as elementary analysis. In this process carbon and hydrogen are determined simultaneously, whilst a separate analysis must be carried out for the determination of each of the other elements. [Pg.46]

The net effect of aU the chemistry is that light from the sun is used to drive life processes. Carbon dioxide taken up in photosynthesis is released in respiration. [Pg.20]
