potential of the chitin filler as shown in Table 3 . The weight loss on ignition is a measure of the carbon content lost during combustion and equally an indication of the effectiveness of the material. The higher the value, the greater the reinforcing

that of the specimens of NRS (Natural River Sand) at 28 days of curing [ 21, 22 ]. In another study [ 23 ], two types of FA (Fly ash) were developed with class F (High carbon content) geopolymer fine aggregate (F-GFA) and class C (Low carbon content

, were obtained by ex situ thermal decomposition of the precursor under N 2 atmosphere or in situ thermal decomposition to increase their surface area or adjust their carbon content. Their HDS activity and DDS selectivity were also investigated in the

NiO/γ-Al 2 O 3 The quantity of coke formed during reaction can be determined by the weight loss during 350–650 °C. The carbon content of fresh NiO/γ-Al 2 O 3 and NiO-C/γ-Al 2 O 3 catalyst is 0 and 2.7 wt
