The separation of resin acids and bases has been described previously (II, 12), see also comments in (14). The percentage of resins, as determined for deasphaltened Athabasca bitumen by their separation on an Attapulgus clay column, was 34%, while combined acids, bases, and Lewis bases amounted to 25.9% of the whole bitumen. Thus, 8.1% of material retained as resins on Attapulgus clay did not interact with the ion exchangers or the complexation column and appeared in the polyaromatic fraction. The distribution of material within the resin fraction was 46.1% acids, 21.9% bases, and 32% neutral compounds. Thus, the pattern of acid and base distribution is similar for the resins and asphaltenes, except for a higher proportion of neutral material present in the resins. [Pg.96]

The daily allowance for basic protection is paid out as a base amount, irrespective of previous earnings. The amount is fixed by the government and is currently set at SEK 320 per day. [Pg.267]

For theE D and basic research credits, the amount of each Credit earned by a particular company is defined as 20 percent Of the difference between qualifying expenses in the current year and the base amount. The amount of credit actually claimed, however, adds in credits earned in earlier years that are carried forward to the current year or subtracts credits earned in the current year but unused due to insufficient tax liability. [Pg.195]

When it comes to natural gas and electricity purchasing, the plant could face contract management issues and better contract management could save millions of dollars per year. This is because the plant could set up a contract with a choice of a fixed amount with a flat cost or a tied structure with different prices. For a tied stmcture, the base amount is fixed with a flat price while additional amounts can be provided with price(s) higher than the base price. With better forecasting, the plant wdl predict the amount of deficit in fuel and electricity and make the purchase contract well in advance. This could dramatically reduce purchasing costs depending on the contract terms. [Pg.486]

The add or base/alkoxide ratio influences the rates of condensation and hydrolisis. The increasing of the acid amount favours the hydrolisis reactions and as a consequence the formation of weakly cross-linked polymeric chains. These phenomena can explain the increase of the surface area, doe to the microporosity. An opposite behaviour is shown by the base-catalyzed 8anq>les. Under basic conditions, condensation reactions are favoured and the resulting sol species are most clusterlike (5). The surface areas decrease with increasing the base amount and the area is due to the mesoporosity only. Using conditions near the neutrality, low amount of acid or base, intomediate structures are formed with surface area of about 400 m2/g. [Pg.407]

Molybdenum is, as mentioned, present as molybdenite MoSj as an associated sulfide in copper deposits and as the principal sulfide in large low-grade porphyry molybdenum deposits. The reserve base amounts to about 11 milHon tonnes (counted as molybdenum) in the whole world, half of which is in the USA. These resources are enough to supply world needs for the foreseeable future. [Pg.598]

By tuning reaction parameters such as temperature, pressure and substrate to catalyst ratio, 100% yield of DMF was obtained (Eq. 22.11). The gold-supported catalyst was reusable taking into account that a special regeneration procedure had to be followed. In the case of FDCA they used the same material and by tuning the reaction conditions, (base amount, temperature and pressure) a yield of 95% was achieved. ... [Pg.647]

Acid strength distribution has been measured by Tanabe and coworkers by means of titration with Hammett indicators as shown in Table 3.15. It can be seen that ZnO is very weak acid. As for the basicity, it was reported that the base amount was 0.05 mmole g for Ho 4.0 in the scale of the acid strength of conjugate acid (see Chapter 2). It was also reported that the acid-base properties are sensitive to pretreatment or environment. ... [Pg.76]

The acidity and basicity increase when ZnO is mixed with other oxides. ZnO —Ti02 becomes more acidic and reveals high activity for hydration of ethylene. Both acid and base amounts increase upon mixing with Si02 and isomerization of butene is catalyzed by the acid sites of ZnO — SiOz Addition of K to ZnO increased the base amount, and the catalytic activity for oxidation of formic acid sharply increased.A mixed oxide catalyst consisting of ZnO and FezOa is a good basic catalyst for the methylation by methanol of phenol to 2,6-xylenol. ... [Pg.77]

Si02 — ZnO. Incorporation of transition metal ions into MgO increases base sites. The relation between the amount of base sites on metal cation-added MgO and ionic radii of the metal cations is shown in Fig. 3.45. Increase in base amount is prominent as the ionic radii of the metal cations are close to that of Mg. Metal ions whose ionic radii are close to that of Mg easily replace Mg in the MgO lattice. The replacement results in a deformed lattice and unbalanced electron charge distribution, increasing the basicity. [Pg.114]

Double-bond isomerization of n-butene is described in more detaU in relation to the acid-base properties of catalysts. The rate usually increases either with increasing acid strength and acid amount or with increasing base strength and base amount. As for the selectivity there are apparent correlations with the acidity or basicity of catalysts as summarized in Table 4.1. However, since the correlation is not one-to-one cor-... [Pg.216]

Addition of Ce or Mo to Fe —Cr —K catalysts improves the selectivity. A relation has been reported between the activation energy for styrene formation and the electronegativity of the transition elements added, as shown in Fig. 4.31. The acid and base amounts measured correlated well with the electronegativity. According to this relation, Ce is the most effective for promoting dehydrogenation. It was suggested that Mo adjusts the activity at a moderate level to suppress the undesired formation of benzene and toluene. [Pg.316]
