The Indonesian dolomite market skyrocketed to $460M in 2023 increasing by 199% against the previous year Over the period under review consumption saw a significant expansion Over the period under review the market attained the maximum level at $767M in 2021; however from 2022 to 2023 consumption failed to regain momentum
Catalytic pyrolysis of date palm seeds DPS has been carried out in a pyroprobe connected online with a GC/MS The effect of a HZSM 5 zeolite on the product distribution has been studied at 450 and 500 °C by using different catalyst/biomass mass ratios 1 2 5 and that of a dolomite catalyst at 450 °C using a catalyst/biomass mass ratio of one Product
Abstract For many years sedimentary dolomite rocks have been considered to be primarily a replacement product of the calcium carbonate components comprising the original limestone a process known as secondary replacement dolomitization Although numerous dolomite formations in the geological record are composed of fine grained crystals of micritic
