Influence of Binder

Coke-oven tar (or the solid pitch) has been, and continues to be, widely used as a binder in the production of bituminous coal briquettes. However, it is being replaced to an increasing extent by petroleum-derived products. 

The composition of bituminous coal-tar and tar pitches is very complex and consists of a wide variety of components (Lang, 1966). But the coke-forming components of the pitch are of great importance for briquetting the currently preferred low-volatile coals, and especially for briquetting anthracite coals. These coals do not cake or melt while burning in the furnace thus, the stability of the briquettes depends entirely on the skeleton of pitch coke formed in the briquette structure. Furthermore, the content of coke-forming components in the tar pitch increases as the rate of pitch distillation is decreased. 

Pitch viscosity also exerts a strong influence on the process as do the coal-binder interactions (Clarke and Marsh, 1989a). During the briquetting process, the properties of the binder pitch are changed by heat, duration of the process, air, and steam. These factors can change pitch composition in the thin layer present in the heated briquetting matrix.

A number of parameters change abruptly at the CPVC. Experimental data on the influence of binders, additives, and suitable pigment preparation are shown in Fig. 35, which is a plot of the viscosity versus PVC curves for three samples of one pigment, incorporated in three different offset varnishes [85],...

In order to study the influence of binder on the deactivation of the zeolite due to coking in the propane aromatization, the time-on-stream activity/selectivity of the zeolite catalyst with or without silica binder has been determined for a period of 6.7 + 0.2 h. The results are shown in Figs. 1 and 2. Data on the amoimt of coke formed on the catalysts during their time-onstream are included in Table 1. It was shown earlier that the deactivation of H-GaMFI zeolite in the propane aromatization is mainly due to coking [11]. 

The zeolite catalysts with and without binder are compared for the distribution of aromatics formed over them at the same propane-to-aromatics conversion (3 and 10%) in Table 5. The comparison indicates that the influence of binder on the aromatics distribution is small.

This chapter focuses on the apphcation of polymers in the formulation of binder blends for MIM. A brief summary of the different classifications of binder blends is presented. The rheological, thermal and mechanical properties of a feedstock with EVA/beeswax binder is discussed to highlight the influence of binder-powder interactions on these properties.
