Why isn’t anyone answering? Please have someone from the technical team respond
Typically, producing one ton of methanol requires 2.5 tons of gasified coal + 0.5 tons of thermal coal. The ratio of methanol to propylene conversion in MTO is approximately 3:1 ； The specific consumption of ethylene and propylene to produce one ton of polypropylene raw material varies; depending on the process and product grade, the typical value ranges between 1005 and 1015 kilograms per ton of PP.
1. How many tons of raw coal are required to produce one ton of propylene (which can be calculated in terms of standard coal)? 2. How many tons of methanol are needed to produce one ton of propylene? 3. How many tons of propylene are needed to produce one ton of polypropylene? Answer: 1. To produce one ton of olefins, 10.5 tons of raw materials along with fuel coal are required (lignite; since I am unaware of the carbon content of standard coal, a conversion cannot be made). 2. Theoretically, 2.3 tons of methanol are needed to produce one ton of propylene ； 3. The amount of propylene required to produce one ton of polypropylene varies depending on the manufacturing process; the current standard for evaluation is 1.015.
