High energy requirement of vapour compression refrigeration systems necessitate the increasing need for more reliable, flexible and cost efficient cooling systems alternatives. Energy saving potential, Carbon emission reduction and waste heat utilization of adsorption refrigeration system could be exploited in this regard. Some of the setbacks that hinder adsorption refrigeration systems from real mass production and commercialization can be address by the development of relatively low cost, available and suitable adsorbent materials. This research work seeks to locally produce date-seed activated carbon and test its adsorptive properties for possible application in adsorption refrigeration system. Physico-chemical analysis was carried out using standard established procedures. The average pH-level, porosity, bulk density and iodine number were found to be 9.43, 62.25%, 0.41g/cm3 and 1075mg/g respectively. The Date-seed activated carbon was found to have relatively good adsorptive characteristic in addition to its availability and relative low cost and therefore could be used as adsorbent in refrigeration system
