This paper reports 13 C nuclear magnetic resonance (NMR) analysis of some crackates obtained from asphalt cracking in a micro autoclave under a pool of nitrogen. The cracking was carried out in the presence of Zeolite Socony Mobil #5 (HZSM-5) and locally cheap and readily available clay i.e. Utimanzai Clay (UTIMAC) as catalysts. The crackates obtained in case of each run was analyzed by ...
This paper reports the conversion of asphalt in a micro-autoclave under an inert atmosphere of nitrogen to lighter products. The influence of temperature, contact time and some catalysts, i.e. clay type; UTIMAC, HZSM-5 and sodium silicate, acidic type; phospho-tungstic acid, oxide type; ammonium hepta molybdate, silica gel, nickel oxide and alumina powder, chloride type; stannous chloride and aluminum...
