“…Among these supports, silicaalumina is known to be very effective support for hydrocracking reaction due to its significant acidity. Although various preparation methods such as co-precipitation [33], CVD [34], and sol-gel method [35] can be used for the preparation of silica-alumina, it is reported that silica-alumina xerogel prepared by a sol-gel method has large acidity, high chemical homogeneity, and excellent textural property [36]. This implies that silica-alumina xerogel can serve an efficient acid support in the hydrocracking of paraffin wax.…”
